Churchill’s Iron Curtain speech at Fulton
At Fulton, Missouri, Churchill declares that “an iron curtain has descended across the continent.” The Cold War has a name.

US government historical publication This political-alignment geography uses national and administrative extents; it does not map every military front. Modern-reference perimeters are explicitly recorded where no more suitable reviewed historical geometry was adopted. All source parts and holes are retained.
The Soviet, Yugoslav, Czechoslovak, Sudanese and other historical unions remove later internal borders. Occupation and armistice lines retain their separate meanings.
German occupation zones use the 1949/1950 successor extents as a nearby-date reference. Austrian occupation uses the July 1945 agreement; the initial May deployment differed.
South Yemen uses the 1969 source as a geographic proxy for earlier Aden/protectorates. The boundaries and status of individual protectorates are not resolved at this scale.
Morocco uses the nearest independent 1956 outer perimeter. The separate French/Spanish protectorate boundary lies outside this political-alignment layer, and Cape Juby remains in the Spanish source footprint until 1958.
Dated assignments correct omissions across the legacy views: independent Algeria is non-aligned after July 1962; Greece and Turkey join NATO in 1952, and Spain in 1982. South Yemen is separate from North Yemen, with British administration before late 1967 and the Soviet-aligned Marxist government after 1969.
The narrative date for the chapter is 1946.2; the displayed source state is the named w45 timeline reference. Each layer records its date-specific source intervals and nearest-date choices.

Layer records and reconstruction methods
The moment in context The postwar map began with the places armies had reached. Soviet troops occupied territory in central Europe from the east, while Western forces held ground taken from the opposite direction. Britain, France and other European powers still ruled empires across much of Asia and Africa. In Germany the victors divided both the country and its capital. Berlin lay deep inside the Soviet zone, so the Western powers could supply their sectors only by crossing territory held by the Soviet Union. Access to the city gave Moscow a way to exert pressure without a battle.
From Origins of the Cold War , chapter 1 of The Cold War, 1945–1991 (MAR 1946).
Teach this in 5 minutes Why it happened — The security dilemma — two rational fears. Soviet leaders wanted distance between Moscow and a possible invader. Two invasions through Poland in thirty years, followed by a war that killed…The turn — Moscow, 22 February 1946. A routine question about Soviet opposition to the World Bank prompted George Kennan’s roughly 5,000-word cable of 22 February 1946. He argued that…What it changed — Containment becomes policy. Aid to Greece and Turkey and the Marshall Plan gave containment political and financial force within eighteen months; NATO followed later. Kennan…Then ask the room: Was the Cold War inevitable in 1945, or did avoidable choices make it? The argued answer is on the chapter page →
