1989

1989 (MCMLXXXIX) was a common year starting on Sunday (dominical letter A) of the Gregorian calendar, the 1989th year of the Common Era (CE) and Anno Domini (AD) designations, the 989th year of the 2nd millennium, the 89th year of the 20th century, and the 10th and last year of the 1980s decade. It was a historical turning point for the wave of revolutions that swept the Eastern Bloc, starting in Poland that summer with the beginning of a move towards private enterprise, coming to a head with opening of the Berlin Wall in November, embracing the overthrow of the communist dictatorship in Romania in December and ending in December 1991 with the dissolution of the Soviet Union. Collectively known as the Revolutions of 1989, they heralded the beginning of the post–Cold War period.

It was the year of the first Brazilian presidential elections in 29 years, since the end of the military government in 1985 which commanded the country for more than twenty years, and marked the redemocratization process's final point. F. W. de Klerk was elected in South Africa, and his regime gradually dismantled the apartheid system over the next five years, culminating with the 1994 election that brought jailed ANC leader Nelson Mandela to power. The Echo Boom in the United States reached its peak in 1989–1990.
