June 5, 1947 — The Marshall Plan is announced

Named for then US Secretary of State George Marshall, the Marshall Plan is one of the largest foreign aid schemes ever put in place by any nation. Beginning in 1948 and ending in 1951, the Marshall Plan gave over 12 billion dollars worth of aid to various Western European nations, intending to help them rebuild after World War Two.

In all, 16 nations – Portugal, Iceland, Ireland, the United Kingdom, France, Italy, West Germany, Belgium, Luxembourg, Holland, Switzerland, Austria, Norway, Sweden, Greece and Turkey – received differing amounts to assist in reconstruction, particularly of their industrial capacity and general infrastructure. The plan was originally supposed to last until 1953, but America was unable to afford this largess and the war in Korea at the same time.

July 1964 — Manufacture of the Neutron Bomb begins

When it was first created, the Neutron Bomb was hailed as a triumph of efficiency and progress. In theory, it would kill the population of its affected area, while leaving the buildings standing. The bomb would have a lesser degree of heat and concussive force than an ordinary nuclear bomb, but a greatly increased amount of radiation.

The bomb was never used in a combat situation, and its production has been largely discontinued. The United States, the Soviet Union, China and France all had developed neutron bombs, but no country is currently known to deploy them.

December 11, 1989 — The Communist Party of Bulgaria relinquishes power

Like the Communist Parties of all the Eastern European states, the Bulgarian Communist Party found its power and authority undermined by the reforms made by Mikhail Gorbachev in the Perestroika era. The immediate cause of the fall of the Communists was the break up of a demonstration in Sofia in October 1989. Public outcry led to the replacement of Todor Zhivkov, the ruling autocrat, with Petar Mladenov, but this was too little too late.

As the people of Bulgaria remained restive, and as other Communist states in Eastern Europe fell (notably the fall of the Berlin Wall in East Germany and the Velvet Revolution in Czechoslovakia that November), demands for similar reforms mounted. Finally, Mladenov complied. On December 11, he announced on national television that Communist Party would relinquish power, and in June of the following year, the first free elections since 1939 were in held.
