The Berlin Blockade (June 1948 to May 1949) and Airlift, the formation of NATO (April 1949), and the division of Germany into the Federal Republic (May 1949) and the German Democratic Republic (October 1949)

What this dot point is asking

NESA expects you to explain how the Berlin Blockade transformed the diplomatic Cold War into a militarised confrontation, how the Airlift's success made Western containment credible, and how the year 1949 produced two German states, NATO, and a Soviet atomic bomb.

The answer

Background, 1945 to 1948

The four-power occupation agreed at Yalta and Potsdam had left Berlin, 110 miles inside the Soviet zone, divided into four sectors. The Allied Control Council was supposed to govern Germany jointly; in practice the zones evolved separately. The American and British zones merged into Bizonia on 1 January 1947 to reduce occupation costs and rebuild West German industry. France joined on 8 April 1949, creating Trizonia.

The London Conference (February to June 1948) of the three Western powers and the Benelux agreed on a West German federal state. Soviet Marshal Sokolovsky walked out of the Allied Control Council on 20 March 1948, ending four-power government in practice.

The Western Allies announced currency reform on 18 June 1948, replacing the inflated Reichsmark with the Deutsche Mark at a 10 to 1 rate in the western zones. The new currency was extended to West Berlin on 23 June. The Soviets responded with the Ostmark in their zone and closed the rail, road, and canal links to West Berlin on 24 June 1948.

The Berlin Blockade, 24 June 1948 to 12 May 1949

Stalin's calculation: about 2.5 million West Berliners depended on outside supply; without surface access, the Western Allies would have to abandon Berlin or abandon the new currency and West German state.

The Western response: General Lucius Clay, American military governor, wanted to send an armed convoy down the autobahn. Truman vetoed escalation but authorised the Airlift on 26 June 1948. The first C-47 landed at Tempelhof on the same day; the first British York landed at Gatow on 28 June.

The Berlin Airlift

The three air corridors agreed in November 1945 (Hamburg, Hanover, and Frankfurt to Berlin) provided guaranteed access at 10,000 feet. Soviet interference with the corridors had not been agreed and was never attempted (although harassment and shadowing did occur).

Operation Vittles (American) and Operation Plainfare (British) flew C-47s, C-54 Skymasters, RAF Yorks, and Sunderlands (which landed on the Havel). General William Tunner, drawing on his China-Burma "Hump" experience, imposed strict timing: aircraft three minutes apart, one approach pattern only, no holding.

Statistics: 277,569 flights, 2.325 million tonnes delivered, of which 1.5 million tonnes was coal. Daily peak 12,941 tonnes on 16 April 1949 ("Easter Parade"). The minimum survival requirement was 4,500 tonnes per day. Costs: $224 million American, 39 British and 31 American dead in crashes.

Stalin lifted the blockade on 12 May 1949. The Airlift continued until 30 September 1949 to build up reserves.

NATO, 4 April 1949

The Brussels Pact (17 March 1948) between Britain, France, and the Benelux had created a defensive alliance after the Czech coup. The North Atlantic Treaty was signed in Washington on 4 April 1949 by 12 founders: the Brussels Pact five, plus the United States, Canada, Norway, Denmark, Iceland, Italy, and Portugal. Greece and Turkey joined in 1952; West Germany joined in 1955, prompting the Warsaw Pact (14 May 1955).

Article 5: "an armed attack against one or more of them in Europe or North America shall be considered an attack against them all." The phrase "shall be considered" preserved national discretion on the response.

The treaty institutionalised American military commitment to Europe and ended the historic American refusal to enter peacetime alliances.

Two German states

The Parliamentary Council under Konrad Adenauer drafted the Basic Law (Grundgesetz) at Bonn, adopted on 8 May 1949. The Federal Republic of Germany was proclaimed on 23 May 1949. Adenauer was elected first chancellor on 15 September. Federal elections (14 August 1949) gave the CDU and CSU 31 per cent.

The German People's Council in the Soviet zone proclaimed the German Democratic Republic on 7 October 1949 under Walter Ulbricht's Socialist Unity Party (SED). Wilhelm Pieck became president, Otto Grotewohl prime minister. The single-list elections were not competitive.

The Soviet bomb

The USSR tested its first atomic device ("First Lightning," at Semipalatinsk) on 29 August 1949. The American monopoly of four years had ended. Mao proclaimed the People's Republic of China on 1 October 1949. The geopolitical position at the start of 1950 was unrecognisable from 1945.

Timeline

Historiography

The orthodox view (Schlesinger, Feis) treats the blockade as Soviet aggression defeated by Western resolve. Revisionists (Kolko, Gaddis in his early work) argue Western currency reform forced Stalin's hand. Vladislav Zubok's A Failed Empire (2007), using Soviet archives, treats the blockade as a Stalin improvisation rather than a planned offensive, made in the belief the Western position in Berlin was untenable.

Common exam traps

Treating the Airlift as a tactical success only. It was a strategic and ideological victory that legitimised long-term American presence in Europe.

Forgetting currency reform was the trigger. Without the Deutsche Mark, no blockade.

Misdating NATO. 4 April 1949, signed during the blockade but before it was lifted on 12 May. NATO was decided before the outcome.

In one sentence

Between 24 June 1948 and 12 May 1949 the Berlin Blockade tested Western resolve, the Airlift's 277,000 flights and 2.3 million tonnes of supply defeated Stalin's hope of compelling abandonment, NATO (4 April 1949) institutionalised the American military commitment to Europe, and by October 1949 two German states, a Soviet atomic bomb (29 August), and a communist China (1 October) had transformed the Cold War into a global militarised confrontation.
