The story starts with the older doctrine Keynes had to break: markets were assumed to clear through production, saving and flexible prices.
Jean-Baptiste Say's early nineteenth-century market theory was later summarized as the claim that supply creates its own demand. Keynes made that classical confidence in self-correction his explicit target: if aggregate demand can fall short, unemployment can persist without an automatic market cure.
Keynes first became a public force as a critic of deflationary punishment after World War I, not as a textbook macroeconomist.
In November 1919 John Maynard Keynes published his attack on reparations, arguing that a ruined Germany could never pay. The book sold over 100,000 copies in six months and made him world-famous.
In November 1919, John Maynard Keynes, the young Cambridge don, published The Economic Consequences of the Peace.Lords of Finance
The gold-standard problem pushed Keynes toward managed money and domestic stability before the Depression made unemployment the central question.
In December 1923, Keynes published A Tract on Monetary Reform, his first systematic attempt to explain the postwar monetary instability. Much of it had already appeared in the Manchester Guardian during 1922 and early 1923.
In December 1923, Keynes published a short monograph, A Tract on Monetary Reform, much of which had already appeared as a series of articles in the Manchester Guardian during 1922 and early 1923Lords of Finance
His Churchill pamphlet is the practical bridge: defend gold and wages must fall; manage money and unemployment becomes a political choice.
also in The central bankers and the road to war
John Maynard Keynes published The Economic Consequences of Mr. Churchill, arguing the overvalued pound would force wage cuts and unemployment. His warning proved accurate as British industry struggled through the late 1920s.
By 1930 Keynes was describing the Depression as a breakdown of the economic machine, not a deserved purge.
In December 1930 Keynes published “The Great Slump of 1930,” calling it one of the greatest economic catastrophes in modern history. He still hoped resolute central-bank action could restart the stalled economy.
IN December 1930, Maynard Keynes published an article titled “The Great Slump of 1930,” in which he described the world as living in “the shadow of one of the greatest economic catastrophes of modern history.”Lords of Finance
Kahn supplied a mechanism: one round of public investment can create further rounds of income and employment.
In June 1931 Richard F. Kahn published "The Relation of Home Investment to Unemployment" in The Economic Journal. The article gave the employment-multiplier logic that Keynes and his Cambridge circle would fold into the case for public works and demand management.
The rival diagnosis was already clear at the LSE: for Hayek, intervention risked distorting capital; for Keynes, inaction let unemployment harden.
also in The Chicago School and the rise of neoliberalism
Hayek publishes a critical review of Keynes's Treatise on Money, opening a running exchange between the two economists over the causes of business cycles and the proper role of government spending. Keynes argued that active fiscal policy could smooth recessions, while Hayek held that credit expansion caused the malinvestment that produced them. The dispute became the defining rivalry of twentieth-century macroeconomics and shaped the LSE-Cambridge divide.
The New Deal made state action visible before Keynesian economics became the official language for explaining it.
also in Capitalism, liberalism, and the isms, The welfare state
Franklin Roosevelt takes office amid the Depression and drives through a wave of relief, recovery, and regulatory legislation in his first hundred days. The New Deal redefines the state's role in a capitalist economy.
Roosevelt did not wait for The General Theory, but his gold move showed the same policy direction: escape deflationary discipline.
also in The central bankers and the road to war
President Franklin Roosevelt suspended gold convertibility and later devalued the dollar to fight deflation. Freeing monetary policy from gold helped the American economy begin to recover.
Kalecki keeps the frame honest: Keynesian economics was also a wider demand-led turn produced by the crisis of capitalism.
Michal Kalecki developed an independent demand-led macroeconomics in the early 1930s, before The General Theory appeared in English. His work is a useful warning against treating Keynesian economics as one man inventing the whole field from nothing; similar problems were pushing several economists toward aggregate-demand explanations.
This is the hinge: persistent unemployment becomes theoretically possible, and aggregate demand becomes a policy target.
also in Capitalism, liberalism, and the isms
John Maynard Keynes publishes The General Theory of Employment, Interest and Money, arguing that governments must manage demand to prevent mass unemployment. Keynesian economics dominates Western policy for the next four decades.
Hicks turned the book into a teaching model, which helped Keynesianism spread but also narrowed what later readers meant by Keynes.
John Hicks published "Mr. Keynes and the Classics: A Suggested Interpretation" in Econometrica in 1937. The IS-LM model made Keynesian economics teachable as a two-market diagram linking income, saving, investment, money demand and interest rates, even as later Keynesians argued that the simplification muted Keynes on uncertainty.
The domestic argument over demand management became a global monetary argument over liquidity, adjustment and creditor power.
In April 1943, the American and British Treasuries published the White and Keynes plans for creating multinational finance entities. These competing visions would shape postwar monetary institutions and global financial power.

This card matters because Keynesian demand management met geopolitics: the creditor country wrote the stronger rules.
also in The passing of the torch: how the American century replaced the British one
John Maynard Keynes, leading the British delegation, proposed an International Clearing Union and a neutral reserve unit he called bancor to spread the burden of adjustment between creditors and debtors. The American negotiator Harry Dexter White rejected the plan in favor of a dollar-centered system, and the United States, holding most of the world's gold and capital, got the design it wanted.
Bretton Woods built a managed world economy, but not the symmetrical clearing union Keynes wanted.

Delegates from forty-four nations agreed to fix exchange rates to the US dollar, which was convertible to gold. The conference also created the International Monetary Fund and the World Bank.
Keynes died just as the postwar order was being institutionalized; Keynesianism then became the work of successors.
Two years after Bretton Woods, Keynes's heart gave out and he died at the age of sixty-one. His wartime efforts had severely damaged his health.
Two years later, Keynes’s heart finally gave out and he died at the age of sixty-one.Lords of Finance
After the war, macroeconomic stabilization became an explicit responsibility of the state.
President Harry Truman signed the Employment Act on 20 February 1946, making maximum employment, production and purchasing power a formal federal policy responsibility. The final act was less sweeping than the original full-employment bill, but it created the Council of Economic Advisers and locked macroeconomic management into the machinery of the US state.
The continuance of a vast national mass market was further assured when, early in 1946, Congress passed the Employment Act, which committed the federal governmentThe Visible Hand
Textbooks translated Keynes into the postwar common sense of mixed economies and managed business cycles.
also in Curriculum, programming, and propaganda
Paul Samuelson's Economics: An Introductory Analysis first appeared in 1948 and became the defining economics textbook for generations of students. Its later editions popularized the neoclassical synthesis: Keynesian demand management for macroeconomic slumps, combined with neoclassical tools for ordinary market analysis.
The monetarist counterattack reframed the Depression as a monetary failure, not primarily a fiscal-demand failure.
also in The Chicago School and the rise of neoliberalism
Milton Friedman and Anna Schwartz publish A Monetary History of the United States, 1867-1960, arguing that the Federal Reserve's contraction of the money supply turned a recession into the Great Depression. The book laid the empirical foundation for monetarism, the theory that stable control of the money supply, not fiscal spending, was the key to economic stability.
The managed postwar monetary order broke under dollar pressure, inflation and reserve strain.
also in Money and finance, The IMF, the World Bank, and the developing world
When the United States ended the dollar's convertibility to gold in 1971, the system of fixed exchange rates the IMF was built to police broke down. The Fund reinvented itself around crisis lending and policy advice.
Stagflation was the great legitimacy crisis: high unemployment and high inflation arrived together.
The 1970s brought high inflation together with weak growth and unemployment, a combination that old Keynesian fine-tuning handled poorly. The Great Inflation, oil shocks and collapsing confidence gave monetarists and new classical economists their opening against the postwar Keynesian consensus.
Hayek's prize marked the intellectual recovery of anti-Keynesian and market-liberal economics.
also in The Chicago School and the rise of neoliberalism
Friedrich Hayek shares the Nobel Memorial Prize in Economic Sciences with Gunnar Myrdal for their work on money, economic fluctuations, and the interdependence of economic, social, and institutional phenomena. The award gave fresh international visibility to Austrian School and free-market economics after decades in which Keynesian economics had dominated the mainstream.
Friedman then became the strongest mainstream rival: money, expectations and policy lags against fiscal fine-tuning.
also in The Chicago School and the rise of neoliberalism
Milton Friedman receives the Nobel Memorial Prize in Economic Sciences for his work on consumption analysis, monetary history and theory, and the complexity of stabilization policy. The award cemented monetarism and Chicago School economics as a mainstream rival to Keynesianism at the highest level of the profession.
Volcker made the anti-inflation turn real policy, with recession as the price of restoring monetary credibility.
also in The Chicago School and the rise of neoliberalism
The Federal Reserve under Paul Volcker sharply raises interest rates, pushing the federal funds rate above 19 percent to break the inflation of the 1970s. The policy triggered a severe recession and high unemployment in the early 1980s but succeeded in bringing inflation down, and it is widely seen as the practical vindication of monetarist thinking in U.S. policy.
Keynesianism survived by changing form: sticky prices and frictions replaced older hydraulic fine-tuning.
By the 1980s and early 1990s, New Keynesian economists rebuilt parts of Keynesian macroeconomics with microfoundations: sticky prices, imperfect competition, credit frictions, coordination failures and other reasons markets may not clear quickly. The result was not old Keynesianism restored unchanged, but a new mainstream synthesis.
The financial crisis brought back the central Keynesian question: what happens when private demand collapses?
The 2007-09 financial crisis drove output and employment down sharply, pushed interest rates to the lower bound and revived the case for fiscal stimulus alongside unconventional monetary policy. Keynesian economics returned as practical crisis language: demand collapse, liquidity support, multipliers and stimulus.
ARRA is the policy card for the revival: fiscal stimulus as a live tool, not just a history-book doctrine.
On 17 February 2009, President Barack Obama signed the American Recovery and Reinvestment Act, a fiscal stimulus package of spending, transfers, state aid and tax relief designed to support demand during the Great Recession. It also included education programs such as Race to the Top, but the macroeconomic point was demand rescue.
On February 17, 2009, President Obama signed into law the American Recovery and Reinvestment Act of 2009 (ARRA), which was the major economic stimulus bill designed to pull the economy out of a near-collapsed condition.Technocracy Rising
the centrepiece of fiscal policy – and certainly the most Keynesian measure – was the 2009 American Recovery and Reinvestment Act (ARRA), a combination of tax cuts and spending projects that was expected to cost $825 billion over two years, or around 5.8 per cent of projected GDP.The Ascent of Money
Greece turned the post-2008 debate into a hard case: consolidate fast, or let demand recover first?
also in The IMF, the World Bank, and the developing world
The IMF, European Commission, and European Central Bank imposed successive austerity programs as Greece's economy shrank by roughly a quarter and unemployment soared. The scale of the downturn reignited the debate over whether harsh conditions help or harm.
The multiplier returned as evidence, not slogan, when forecasts missed how much austerity would hurt output.
In January 2013 Olivier Blanchard and Daniel Leigh published an IMF working paper showing that, early in the post-2008 crisis, stronger planned fiscal consolidation was associated with worse growth forecast errors. The natural interpretation was Keynesian: fiscal multipliers had been larger than many official models assumed.
The IMF evaluation turned that debate back onto the institution itself.
also in The IMF, the World Bank, and the developing world
An internal IMF evaluation admitted it had underestimated the damage austerity would do to Greece's economy. The rare public self-criticism strengthened arguments that the Fund's fiscal multipliers had been wrong.
COVID completed the arc: in crisis, even governments skeptical of ordinary Keynesianism used massive demand support.
The CARES Act, enacted on 27 March 2020, authorized emergency fiscal support on a scale far beyond ordinary recession policy. CBO estimated roughly 1.7 trillion dollars in added deficits over 2020-2030, reflecting direct payments, unemployment support, business rescue, health spending and Fed-backed credit facilities.
