Upon his rise to power, he eased press censorship and openly condemned the Warsaw Pact invasion of Czechoslovakia in his speech on 21 August 1968, which resulted in a surge in popularity. However, the resulting period of stability was brief as his government soon became totalitarian and was considered the most repressive in the Eastern Bloc at the time. His secret police, the Securitate, was responsible for mass surveillance as well as severe repression and human rights abuses within the country, and controlled the media and press. Economic mismanagement due to failed oil ventures during the 1970s led to skyrocketing foreign debts for Romania. In 1982, Ceaușescu directed the government to export much of the country's agricultural and industrial production in an effort to repay these debts. The shortages that followed drastically lowered living standards, leading to heavy rationing of food, water, oil, heat, electricity, medicine and other necessities. His cult of personality experienced unprecedented elevation, followed by extensive nepotism and the intense deterioration of foreign relations, even with the Soviet Union.
