In 1948, Mr. Apostol became a Politburo member of the Communist Party, and he served as the party's general secretary from 1954-55 and as Romania's agriculture minister from 1953-54.
After longtime Romanian leader Gheorghe Gheorghiu-Dej died in 1965, Mr. Apostol was defeated in a contest for Communist Party leader by Ceausescu, who ended up ruling Romania with an iron fist for almost 25 years.
Mr. Apostol was soon considered the dictator's rival and, acting on the advice of senior party members, he became a diplomat and served as Romania's ambassador to Argentina in the 1970s and later in Brazil before returning to Romania in 1988.
Mr. Apostol gained international attention by signing the "letter of the six," in March 1989 in which he and five other senior communists publicly criticized Ceausescu for the first time. In the letter, they opposed the ruler's plans to destroy thousands of villages and accused him of damaging the country's economy and reputation abroad.
The letter was broadcast on Radio Free Europe and Voice of America, and a short time later Mr. Apostol was accused of being a Soviet spy and placed under house arrest.
He was released during Romania's anticommunist revolt in December 1989, during which Ceausescu was executed in a bloody revolt that killed more than 1,000 people.
Soon afterward, Mr. Apostol retired from public life, and he rarely spoke in public.
