The KGB: Sword and Shield of the Communist Party

It was the sword and shield of the Communist Party, a shadowy, global organization that would strike fear into the West and the Soviet Union alike. The KGB, with a Russian-language name translating to the Committee for State Security, was one of the largest and most formidable intelligence organizations that the world has ever seen. Over nearly four decades of operation, the KGB would enter into direct competition with the American CIA and many parallel intelligence groups around the world, while harshly and often violently suppressing political and nationalist dissidence on Soviet soil. Even now, much of the KGB’s work remains shrouded in secrecy decades after the agency was dissolved, but what is known paints a clear picture of an elite intelligence organization that was willing to do anything to protect its mother country, all the way up until the bitter end.

From the Cheka to the KGB: A Brutal Lineage

The KGB’s origins trace back to the Cheka, the Soviet Union’s first secret-police organization. Overseen by Felix Dzerzhinsky, the Cheka was the organization responsible for setting up early labor camps, suppressing rebellions and mutinies after the rise of the Soviet Union, and otherwise constructing the architecture Vladimir Lenin believed was necessary to protect the interests of the Soviet revolution. The Cheka was an extremely nasty organization, known for its mass arrests, its liberal use of torture and summary execution, and its scorched-earth repression of discontented peasants, and it was from this legacy that the later guiding principles of the KGB would emerge.

Over the next several decades, the Soviet Union’s intelligence apparatus would proceed through a veritable alphabet soup of new and quickly discontinued secret-police forces. The Cheka would give way to the GPU, aided by the INO, then the GPU became the OGPU, which became the NKVD assisted by the GUGB, then the NKGB, then a different NKGB, then the MGB, then the MVD. Each iteration of the Soviet secret police would generally be defined by three major factors: an expansion or change in its mission, for example due to the Second World War or the new pressures that come from a more developed Party apparatus; a series of important lessons learned and new operational capabilities they developed; and an ignominious ending that was typically part of a larger Soviet shakeup that came around every couple of years.

Key Takeaways

  • The KGB was established in 1954 after Khrushchev overthrew Beria’s troika and purged the prior intelligence apparatus to create an agency directly subordinate to Party leadership.
  • In 1983, approximately one-third of Soviet diplomatic employees in embassies and consulates were believed to be undercover KGB operatives classified as Legals.
  • Robert Hanssen spied for the KGB within the FBI for over two decades, while Aldrich Ames compromised over a hundred CIA covert operations and caused the deaths of at least ten agents — together representing the most catastrophic Western intelligence failures of the Cold War.
  • Operation Cedar was a ten-year KGB plan to catastrophically disrupt US power infrastructure including hydroelectric dams, oil refineries, and the Port of New York, though the attacks were never carried out.
  • After the Soviet Union’s collapse, the KGB’s domestic functions were rolled into the FSB — whose director Vladimir Putin once was — and its foreign intelligence arm became the SVR, both of which continue to operate today.

After the death of Joseph Stalin in 1953, the leader of what was then known as the NKVD, Lavrentiy Beria, formed a three-way leadership agreement known as a troika, which would oversee the country in the wake of Stalin’s demise. Beria was a uniquely cruel character in his time, about what one would expect from the last and most successful of Stalin’s secret-police chiefs, and he had gained a reputation for large-scale massacres in Poland, forced relocation of many minority populations from the Caucasus mountains, and the expansion of Stalin’s Gulag program. He had also guided the integration of many Eastern European states into the Soviet Union, and overseen the Union’s efforts to successfully build an atomic bomb.

Not only had Beria long been a centerpiece of the Soviet Union’s greatest upheavals, but also one of its most deeply entrenched officials, and a pivot into Stalin’s role as dictator wouldn’t have been too much of a surprise. But that all changed in June 1953, just months after Stalin’s death, when Nikita Khrushchev overthrew the leading troika and saw to it that Beria was executed. With his death, so died the Soviet state police as Beria had constructed it.

Establishment and Structure of the KGB

Among Khrushchev’s many steps to consolidate his power was a purge of Beria’s high-level associates, including many within the state intelligence apparatus. Although this choice meant that Khrushchev’s new secret police might lose out on their experience and expertise, it also provided an essential form of ideological culling that would allow the next organization to start fresh. When the KGB was established in 1954, it would take a leading role in the purge of Lavrentiy Beria’s supporters, hunting down anybody who might pose a threat to Khrushchev’s rule while pulling any relevant players in the Soviet intelligence world into the new agency’s orbit.

From the start, the KGB was set up in a meaningfully different way than most of the Soviet Union’s prior secret-police organizations, as the Party had by now learned the hard way that the secret police had a tendency to spiral their operations out of the Party’s control. This time, the KGB would operate in a way directly subordinate to Party leaders, with a regimented military structure that positioned the Soviet state clearly at the top of the pyramid. At least from the outside, it would appear that this choice paid off—the KGB would persevere through the demise of the Soviet Union decades later, instead of simply being purged and restructured yet again when Khrushchev himself was deposed in 1964.

When the KGB took the reins from the NKVD, it was subdivided shortly after into some twenty-odd directorates, each responsible for various roles and responsibilities within the government. By the fall of the Soviet Union, the agency had grown into a highly robust, broad-scope organization, with carefully constructed redundancies to guard against its own demise. Some of the most important directorates included the KGB’s branches for external and international intelligence, counterintelligence within the Soviet Union, protection of high-level Party officials, and the political police, who worked to suppress anti-Soviet or opposition political movements within the Soviet states.

Other less impactful but unique directorates included large-scale units dedicated to cryptography, wire-tapping and surveillance of enclosed spaces, and units to combat organized crime. The KGB was also a cover-all organization; guards on the Soviet border were KGB agents, the institution had its own division of Spetsnaz special-forces troops, and it was responsible for field reconnaissance to support military operations. The KGB’s 15th Main Directorate was built to oversee command-and-control structures that the government would use in the event of a major war, while the Close Protection Service fulfilled a function similar to that of the American Secret Service.

The Directorate Z existed first to censor artistic and intellectual dissent, and then to protect the Soviet Union’s constitutional order, a mandate that superseded any one autocrat who might lead the Soviet state astray. The organization adopted a strict military hierarchy, with clear standards of internal discipline and a parallel rank structure to the Soviet armed forces. Since the Soviet Union was a federal state consisting of a large number of constituent Republics, each Republic had its own KGB, all subordinated to the Chairman of the KGB.

Legals, Illegals, and the Art of Espionage Abroad

A lot of the KGB’s real punching power came from its operatives abroad, which were subdivided into two basic categories: so-called “Legals” and “Illegals.” The Legals were personnel headquartered in Soviet embassies and consulates, where in 1983, about a third of diplomatic employees were believed to be KGB employees undercover. They were referred to as Legals due to their ability to operate within a host country under visas and diplomatic protections granted by those countries.

Other Legals would enter various countries as representatives of the Soviet press corps or international business interests, providing their support to the known operatives at work in Soviet diplomatic offices. The Illegals, however, were what most people would think about when imagining a Soviet spy operation: agents with a false identity, fluency in the language spoken in their target nation, and a deeply reinforced personal history and backstory that would allow them to infiltrate far into the nation where they were stationed. Often, these agents would go inactive for years before carrying out an intelligence operation, building lives overseas while awaiting orders.

For many of the Illegals, intelligence-gathering was as simple as getting information back to the Soviet Union if it was publicly available elsewhere, in order to help the Soviets see through the fog of war that came from a basic lack of cultural interactions with the West. In other scenarios, the Illegals would gather far more sensitive or well-guarded intelligence and spirit it away to their handlers. Their cover identities would either be tailored directly to the needs and strengths of the individual spy, or on occasion, they would essentially be a body-double for a real person who was in on the secret.

This human-intelligence operation was the KGB’s bread and butter overseas, where their agents learned to blend in better and better until they became almost seamless facades of an ordinary Western citizen. Just as important as sending personnel abroad was the ability of those personnel to recruit or compromise human assets—Westerners who either joined the KGB’s operations willfully or were coerced into doing so. One KGB defector estimated that in West Germany, some 1,500 citizens became Soviet spies in the early 1970s, and while actual numbers are unknown, it is abundantly clear that the KGB cultivated assets heavily from Western governments, businesses, and scientific institutions.

Many of these assets were recruited out of genuine support for the Soviet cause, although various international anti-communist efforts like the American Red Scare blunted some people’s willingness to join. Others would be coerced into cooperation with blackmail, or via so-called honeytrap operations in which KGB agents would seduce a potential asset before leveraging that personal relationship into an intelligence one. More often, though, they would simply pay off their assets—a technique that usually worked far better than Western organizations would have liked to believe.

Internal Repression, Propaganda, and Direct Action

Within the Soviet Union, the KGB engaged in brutal political repression and gained a knack for shutting down opposition parties without rocking the boat enough to cause a full-scale rebellion most of the time. The KGB’s internal doctrine was organized around identifying and punishing displays of so-called “nonconformity”—the thing that got the KGB looking sideways at somebody wasn’t so much their affinity for one particular ideology or alternative political party, but their broader resistance to a series of Soviet norms. The Soviet Union’s network of Gulag camps was leveraged, the KGB targeted religious minorities while keeping the Russian Orthodox Church firmly in its own pocket, and installed personnel in most major workplaces who would keep an eye out for anti-Communist sentiment.

Often, these operatives would work in staffing or security departments, but for many employees, they became the HR Manager from Hell, keeping close tabs on any potential whiff of subversive activity. In addition to domestic and international human-intelligence collection, the KGB was deeply involved in the creation and proliferation of propaganda both at home and abroad, while working to spread disinformation around the world. The KGB also included strong signals-intelligence and logistical support, and spent a great deal of resources cultivating and protecting the networks of informants and handlers they placed around the world.

Often, they would be involved in infiltrating subversive or potentially damaging organizations, sowing dissent or guiding policy within those groups in order to keep them from becoming a problem. The KGB’s direct-action capabilities worked around the world to assassinate and kidnap targets, foment insurgencies, and supply or train revolutionaries in many of the third countries that would host the Cold War’s endless proxy conflicts. Like the CIA’s Special Activities Division, the KGB’s direct-action elements were widespread around the world, training commandos and insurgents in Cuba, Palestine, and elsewhere, and assisted Western European terrorist groups like the Irish Republican Army, the Italian Red Brigades, and the West German Baader-Meinhof Gang while distributing weapons and crucial intelligence to Marxist and other leftist revolts across the third world.

The KGB also moved massive amounts of money to organizations it deemed favorable—not just revolutions, but anti-war or pro-Communist groups around the world, many of which didn’t even know the source of the funds they were receiving. They were instrumental in laying the groundwork for the Soviet military’s premeditated expeditions abroad from the 1950s through the 1980s, setting up intelligence and supply networks that would expedite military operations.

Recruitment, Training, and Chekist Values

The ranks of the KGB were filled in its early years by a network of state loyalists, the friends and relatives of powerful Party members, and some of the most effective, and often brutal, enforcers of the Party’s will from prior intelligence organizations and the military. But as the KGB began to develop its own unique flavor, it began to draw far heavier on the well-educated, free-thinking young intellectuals of Soviet universities, especially those with fluency in foreign languages. Enticed by higher pay and the prospect of getting out of the worse parts of the Soviet Union, many of these students were more than happy to join up.

The children of military, police, and border personnel were especially in demand, as were the graduates of Moscow’s Institute of International Relations—a veritable finishing school for future spies. Upon being selected for candidacy, young Soviet citizens would typically be invited for an interview in which KGB personnel could explain their role and mission, and candidates could be screened for basic suitability. From there, candidates who passed a battery of secondary and qualifying tests would move on to officer training.

Much of what is known about KGB training comes from a cache of training manuals translated by journalist Michael Weiss in the late 2010s. The manuals, technically classified in Russia even today, cover a wide range of subjects meant to train or coach potential Soviet intelligence officers, focusing on those working as handlers or spies abroad. Among the topics the manuals discuss are how to identify and psychologically manipulate Western sources and cultivate them into intelligence assets, how to identify and combat Western disinformation schemes working on Soviet soil, and how to engage in, and win, the precise chess matches played between Western intelligence agents with whom a KGB officer might cross paths.

The documents provide detailed information on the KGB’s understanding of how to gather human intelligence, including highly specific guides on how to exploit a target’s fears and vices and coerce them into becoming compliant to an intelligence-gathering operation. Formerly classified Soviet papers indicate that KGB recruits were educated in so-called Chekist values—devout loyalty to the Soviet system of government and the Communist Party, and dedication to its defense against enemies foreign and domestic. In addition to espousing these Chekist values and cultivating human assets, the KGB’s intelligence officers were expected to be competent in covert operations, secure communications, cryptographics, and cultural competency in whichever nation around the world where they would be stationed.

Spectacular Operations and Famous Agents

In their decades of operation, the KGB would distinguish themselves with the successful infiltration of every major Western intelligence agency in the world, as well as their ability to place assets at the highest levels of government, military, and business in just about every country they set their sights upon. The rewards for this success included the collection of massive amounts of technical and scientific data, which would guide the Soviet Union’s development of modern technologies, as well as the state secrets of both allies and enemies on the international stage. Internally, they engaged in especially brutal repression, with an overall human cost that might have been as high as the tens of millions in affairs like the Hungarian Revolution and the Prague Spring.

KGB operatives were able to cultivate an asset within the American FBI, an agent named Robert Hanssen, who spied for the Soviet Union and Russia for over two decades straight. Over that time, Hanssen earned well over a million dollars by selling the KGB thousands of classified documents, including American weapons and counterintelligence programs, while also identifying double-agents within the KGB that were actually working for the West. Although he was eventually caught and sentenced to 15 consecutive life sentences, Hanssen and his KGB handlers had already perpetrated a catastrophic infiltration of the US government, revealing state secrets on a level unheard-of in the intelligence world.

Perhaps even worse than Hanssen was Aldrich Ames, a CIA officer who was compromised by the KGB and spent about a decade funneling intelligence to the Soviet Union and Russia, beginning in the mid-1980s. Ames is believed to have compromised over a hundred covert operations during that time, and led to the deaths of at least ten CIA agents and sources. Perhaps the most famous spy of all was Rudolf Ivanovich Abel, who was sent to the USA in the late 1940s and set up a spy ring based in New York City.

Over the following years, he would be an architect in setting up networks to smuggle American secrets to Russia. An East German man named Albert Dittrich, known in the US as Jack Barsky, was sent to the United States and used as a courier while trying to work his way up in American society—an effort that was ultimately unsuccessful, but gave him valuable insight which he later shared with the American public, after a life spent in the United States and the birth of his child in America led him to become disillusioned with the KGB’s dedication to Communism. The work of the KGB went far beyond just information-gathering, and included large-scale plans to disrupt Western society.

Among their more major operations in the US was Operation Cedar, a ten-year operation to lay the groundwork for a severe, even catastrophic disruption of the United States’ power infrastructure. This included a specific focus on targeting massive hydroelectric dams, oil refineries, and pipelines running from Canada into the US, as well as the Port of New York, which would have been blown up. These attacks were never carried out, although why precisely the plan failed is still unclear.

A plan of a similar scale was known as Operation Pandora, which targeted racial divisions rather than power infrastructure within the United States. Operation Pandora’s objective was to exploit racial tensions between White-supremacist organizations and Black militant groups after the assassination of Martin Luther King Jr., in an operation that would have jointly spread disinformation inciting violence from each group, and bombed a historically Black university in New York to kick off a race war. This operation, too, was unsuccessful, but race relations in the United States remained a favorite pressure point of the KGB for several decades.

Globally, the KGB had an appetite for subversion that ran far beyond the United States. The KGB was integral in the Soviet Union’s advance into Afghanistan, fomenting years of political upheaval and directly carrying out a coup with its own operators. In Latin America, operatives propped up friendly regimes like Fidel Castro in Cuba while bringing down pro-American governments and propping up Marxist popular revolution.

Internally within the Soviet Union, the KGB was at the center of a long series of counter-revolutionary efforts in the various Soviet republics, while simultaneously monitoring dissidents, targeting intellectuals and writers, and putting together show trials to either discredit members of the opposition or terrify Soviet citizens into compliance.

Decline, Dissolution, and the FSB Successor

For an organization as powerful and expansive as the KGB, granted an almost sacred mission to guard the Soviet Union from its enemies, it is almost ironic that the forces that would ultimately destroy the KGB were the same ones it worked so hard to serve. In the Soviet Union, corruption and decay at high levels of government were unavoidable, in part because many of the same people perpetuating the corruption were the people tasked with investigating it. In this way, and perhaps only in this way, the Soviet Union might have been better served if the KGB had the authority that its prior intelligence services did, with the latitude to investigate and bring down even high-ranking Party officials in the name of the Union.

But with the KGB placed so intentionally subordinate to the Party, it was powerless to take on the major instigators of the Soviet Union’s eventual collapse. When Mikhail Gorbachev rose to the position of head-of-state in 1985, he came with a series of worldviews and priorities that often placed him at odds with even himself. Though Gorbachev was possessed of a deep understanding, and even a respect of the KGB’s work at home and abroad, he was ultimately more concerned overall with reforming the Soviet state and limiting the authority of many powerful groups, very much including the KGB.

It was no accident that Directorate Z changed its mission in 1989 to focus on preservation of the Soviet Union itself—indeed, that was at the height of Gorbachev’s reforms, when it became clear that Gorbachev’s path offered a choice between a fundamentally different Soviet Union, or a collapse of the state entirely. The KGB continued its work as best as it could, collecting and acting on intelligence wherever possible, but by 1991, the end was nigh. The chairman of the KGB at the time, Vladimir Kryuchkov, was at the center of the coup, and when it failed, much of the KGB’s authority went with it.

First, its military and paramilitary units were shut down; then, its role as a secret police force was sharply curtailed. When the Soviet Union fell, the KGB was a shadow of its former self, as utterly helpless in the face of change as any other piece of the former Party elite. What was left fell under the command of President Boris Yeltsin of Russia.

In the following years, Yeltsin would deconstruct the KGB that had once existed. Its domestic services would be rolled into a new organization that would eventually be referred to as the Federal Security Service, or FSB. Its international components would become the External Intelligence Service, known under its Russian-language acronym as the SVR.

It is the FSB that has become the KGB’s spiritual successor, and it is not lost on anybody in Russia or around the world that under Vladimir Putin, a former KGB operative and FSB head himself, the modern FSB has continued to thrive. Former leaders of the KGB now serve at high levels of the new organization, as well as in ministerial and other government posts across Russia. Unsurprisingly, none of the KGB’s former leaders have been held accountable for the crimes they perpetrated against the citizens of the Soviet Union, nor their brutal legacy of state-sponsored repression of Soviet society writ large.

Even as the official organization of the KGB has long since faded into history, it is the bones of the agency that still exist today: its former leaders, its intelligence network around the world, and its tools to repress political opposition in Russia.

Frequently Asked Questions

How did the KGB differ structurally from earlier Soviet secret-police organizations?

Unlike the NKVD and its predecessors, which periodically spiraled out of Party control, the KGB was deliberately set up to be directly subordinate to the Communist Party leadership. It was subdivided into roughly twenty directorates covering everything from foreign intelligence and counterintelligence to border guards, Spetsnaz forces, cryptography, and a Close Protection Service similar to the US Secret Service — a structure designed with redundancies to prevent any single figure from repeating what Beria had nearly done after Stalin’s death.

What was the difference between KGB Legals and Illegals?

Legals operated from Soviet embassies and consulates under diplomatic cover, accounting for roughly a third of Soviet diplomatic personnel in 1983. Illegals were agents living under deep cover with false identities, often going inactive for years while building ordinary lives before carrying out intelligence operations. While Legals could fall back on diplomatic protections if exposed, Illegals risked arrest with no institutional shield — their value lay in the ability to penetrate targets no official cover could reach.

How did the KGB recruit and compromise Western assets?

The KGB used several methods: genuine ideological sympathy, especially from left-leaning Westerners; cash payments, which KGB defectors acknowledged often worked far better than other methods; blackmail over personal secrets; and “honeytrap” operations in which agents seduced targets before leveraging the relationship. In West Germany alone, one defector estimated roughly 1,500 citizens became Soviet spies in the early 1970s. FBI agent Robert Hanssen and CIA officer Aldrich Ames are the most prominent examples of highly placed assets bought over extended periods.

What were Operation Cedar and Operation Pandora?

Operation Cedar was a decade-long plan to sabotage US power infrastructure at a moment of maximum strategic damage — targeting hydroelectric dams, oil refineries, Canadian pipelines, and the Port of New York. Operation Pandora aimed to exploit racial divisions after Martin Luther King Jr.’s assassination by spreading disinformation to incite violence between White-supremacist organizations and Black militant groups, and bombing a historically Black university in New York. Both operations were ultimately never carried out, though the reasons remain unclear.

What happened to the KGB after the Soviet Union collapsed?

The KGB began losing authority even before the collapse: Gorbachev’s reforms curtailed its power and its military units were shut down after the failed 1991 coup attempt. When the Soviet Union fell, the organization was dismantled by Boris Yeltsin. Its domestic security functions became the Federal Security Service (FSB), its foreign intelligence arm became the SVR, and many former senior KGB officers moved into high government posts in the new Russia — including Vladimir Putin, himself a former KGB operative who headed the FSB before becoming president.
