Communist coup in Czechoslovakia
25 Feb 1948 — A communist coup takes Czechoslovakia, the last democracy east of the curtain, without a shot. Western resistance to Stalin hardens overnight.

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.
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 1949.4; the displayed source state is the named e49 timeline reference. Each layer records its date-specific source intervals and nearest-date choices.

Layer records and reconstruction methods
The moment in context Europe’s recovery was far from assured in the winter of 1946–47. Canals froze, fuel ran short and German rations were halved. The hardship also troubled American policymakers for a political reason. Communist parties in France and Italy had already won around a quarter of the vote; if living conditions remained desperate, they might gain power through elections without a Soviet invasion. The Marshall Plan sought to restore production and give people reason to expect a better future. Recovery was to serve containment.
