Imre Nagy was Prime Minister of Hungary on two occasions. His second term was during the revolution in 1956, and it ended when his non-Soviet-backed government was brought down during the failed Hungarian Revolution. He was tried and executed in 1958, and buried in an unmarked grave. His name could not to be mentioned during Communism, but he became a symbol of freedom. In 1989, he was reburied. A crowd of 200,000 gathered at Heroes' Square for the funeral. His statue, facing the Parliament Building, is located on a tiny square next to Kossuth Square.
