People's Republic of Bulgaria
The Chairman (President) of the Republic of the People's Republic of Bulgaria (Bulgarian: "Председателят (Президентът) на Републиката") was the head of state of Bulgaria from 3 April 1990 to 22 January 1992. The office was known as the "Chairman (President) of the People's Republic of Bulgaria" until the word "People's" was dropped from the country's name on 15 November 1990. From that point on, the office was simply the "Chairman (President) of the Republic of Bulgaria".
