1. The Central Question
The historiography of the Cold War’s end asks: why did the Soviet Union collapse, and why did it collapse when it did? This breaks into several related questions. Was the Soviet collapse the result of internal structural weaknesses (economic failure, national minority nationalism, the unsustainability of the command economyCommand Economy Full Description:An economic system in which production, investment, prices, and incomes are determined centrally by the government rather than by market forces. It represents the antithesis of free-market capitalism. In a Command Economy, the “invisible hand” of the market is replaced by the “visible hand” of the state planning committee (Gosplan). The state dictates what is produced, how much is produced, and who receives it. There is no competition, and prices are set by decree to serve political goals rather than reflecting scarcity or demand.
Critical Perspective:While theoretically designed to ensure equality and prevent the boom-bust cycles of capitalism, in practice, it created a rigid, inefficient bureaucracy. Without price signals to indicate what people actually needed, the economy suffered from chronic shortages of essential goods and massive surpluses of unwanted items. It concentrated economic power in the hands of a small elite, who enjoyed special privileges while the masses endured stagnation and hardship.

The answers matter for how we understand the post-Cold War order that followed: whether it represented a vindication of liberal capitalism, a transitory unipolar moment, or something more fragile.
2. The Main Schools
Reagan Won the Cold War
Core argument: The most influential popular and political account holds that Ronald Reagan’s hard line — the arms build-up, the Strategic Defense Initiative (SDI), the Reagan Doctrine of supporting anti-communist insurgencies, the ideological confrontation — drove the Soviet Union to economic exhaustion and forced Gorbachev to seek accommodation. The Cold War ended because the West, under Reagan, chose to compete rather than to manage.
Key texts: Peter Schweizer, Victory (1994); Paul Kengor, The Crusader: Ronald Reagan and the Fall of Communism (2006).
Strengths: Accounts for the timing (Reagan’s pressure coincided with Gorbachev’s reforms); resonates with the ideological self-understanding of Western Cold War strategy.
Weaknesses: Overstates Reagan’s specific contribution; SDI was not technically viable and Soviet military planners knew it; the Soviet collapse was driven primarily by internal factors that pre-dated the Reagan build-up; professional historians have largely rejected the strong ‘Reagan won’ thesis.
Internal Structural Collapse (Gaddis, Zubok)
Core argument: John Lewis Gaddis’s The Cold War: A New History (2005) and Vladislav Zubok’s A Failed Empire (2007) argued that the Soviet collapse was primarily the product of internal structural failures: an economy that could not deliver material improvement to its population, a political system that could not reform without destabilising itself, national minority movements that the federal structure had suppressed but not resolved, and an ideological legitimacy that had eroded. Gorbachev’s reforms were necessary responses to these internal failures, not the product of Western pressure alone.
Key texts: John Lewis Gaddis, The Cold War: A New History (2005); Vladislav Zubok, A Failed Empire (2007).
Strengths: Based on Soviet archival evidence; explains the timing (structural failures accelerated under Gorbachev’s reforms); accounts for why the collapse came from within rather than through military defeat.
Weaknesses: Can underestimate the role of Gorbachev’s specific ideological commitments and personal decisions; structural explanations can make the collapse seem inevitable when it was not.
Gorbachev’s Agency (Brown)
Core argument: Archie Brown’s The Gorbachev Factor (1996) argued that the Cold War’s end was primarily the product of one man’s decisions: Gorbachev chose not to use force to preserve the Soviet empire in Eastern Europe (the ‘Sinatra Doctrine’ replacing the Brezhnev Doctrine), chose to withdraw from Afghanistan, chose to accept German reunification within NATO, and made these choices on the basis of genuine ideological conviction rather than simply responding to internal or external pressures. Without Gorbachev, the Cold War might have ended differently — or not at all.
Key text: Archie Brown, The Gorbachev Factor (1996).
Strengths: Takes political agency seriously; explains the specific form of the Cold War’s end (peaceful revolution rather than violent collapse); accounts for why the Soviet response to 1989 was restraint rather than another 1956 or 1968.
Weaknesses: Risk of ‘great man’ history that underweights structural factors; Gorbachev’s decisions were themselves shaped by the structural conditions he inherited.
Post-RevisionismRevisionism Full Description:Revisionism was framed as the greatest threat to the revolution—the idea that the Communist Party could rot from within and restore capitalism, similar to what the Chinese leadership believed had happened in the Soviet Union. Accusations of revisionism were often vague and applied to any policy that prioritized economic stability, material incentives, or expertise over ideological fervor. Critical Perspective:The concept served as a convenient tool for political purging. It allowed the leadership to frame a factional power struggle as an existential battle for the soul of socialism. By labeling pragmatic leaders as “capitalist roaders,” the state could legitimize the dismantling of the government apparatus and the persecution of veteran revolutionaries. : Multiple Causation
Core argument: The current professional consensus holds that the Cold War’s end resulted from the interaction of structural Soviet weaknesses, Western pressure (though not Reagan’s alone), Gorbachev’s specific decisions, and the popular pressure from below in Eastern Europe that the Soviet system could no longer contain. No single factor is sufficient; the question is the weight assigned to each.
3. How the Debate Has Developed
The end of the Cold War was initially interpreted in triumphalist terms in the West — liberal democracy and capitalism had prevailed, history had ended (Fukuyama). This interpretation was complicated by the 1990s: the Soviet successor states were not liberal democracies, the ‘peace dividend’ was illusory, and NATO expansion generated Russian resentment that contributed to subsequent crises. The opening of Soviet archives after 1991 provided the evidence base for more sophisticated accounts, while the political stakes of the ‘who won?’ question kept the debate alive.
4. Where the Debate Stands Now
Professional consensus supports a multi-causal account: Soviet internal failures were necessary conditions; Gorbachev’s specific decisions shaped the form the collapse took; Western pressure contributed but was neither necessary nor sufficient alone. The ‘Reagan won’ thesis is rejected by most professional historians as oversimplified. The debate has been given new urgency by the Russian invasion of Ukraine and renewed argument about whether the post-Cold War settlement was managed wisely.
5. For Teachers: Exam Relevance
AQA, Edexcel, OCR: The end of the Cold War is examined across major A-level boards. AO3 questions frequently ask students to evaluate the relative importance of Reagan, Gorbachev, and internal Soviet factors in ending the Cold War.

Archie Brown, The Gorbachev Factor (1996) — The most persuasive account of Gorbachev’s personal role. Essential for the agency argument.
John Lewis Gaddis, The Cold War: A New History (2005) — The most accessible recent synthesis. Essential for the structural account and the post-archive perspective.
Vladislav Zubok, A Failed Empire (2007) — The most important Soviet-side account. Essential for understanding internal Soviet dynamics.
Stephen Kotkin, Armageddon Averted (2001) — The most concise structural account of the Soviet collapse. Excellent on the internal factors.
