In November 1938, Bozhilov became Minister of Finance in the government of Prime Minister Georgi Kyoseivanov,[2] a position which Bozhilov kept when Bogdan Filov became prime minister in 1940. In 1943, after Tsar Boris III died, Filov became one of Bulgaria’s three regents. Filov, a fervent ally of Nazi Germany and the most powerful of the regents, used his power to appoint Bozhilov (another pro-German) prime minister.
