Simeon Saxe-Coburg-Gotha

Simeon Borisov Saxe-Coburg-Gotha (, ; born 16 June 1937) is a Bulgarian politician who reigned as the last tsar of the Kingdom of Bulgaria as Simeon II from 1943 until 1946. He was six years old when his father Boris III of Bulgaria died in 1943. Royal power was exercised on his behalf by a regency council led by Simeon's uncle Kiril, Prince of Preslav, General Nikola Mihov and prime minister, Bogdan Filov. In 1946 the monarchy was abolished by referendum, and Simeon was forced into exile.

Simeon returned to his home country in 1996, formed the political party National Movement for Stability and Progress (NMSP) and was elected Prime Minister of the Republic of Bulgaria from July 2001 until August 2005. In the next elections, as a leader of NMSP, he took part in a coalition government with the Bulgarian Socialist Party. In 2009, after NMSP failed to win any seats in Parliament, he left politics.

, Simeon is one of only two living people who were heads of state from the time of World War II, along with the 14th Dalai Lama, although both held mostly symbolic roles in their government's position. Provided by Wikipedia
