Sparta was ruled by two kings, who ruled until they died or were forced out of office. Athens was ruled by archons, who were elected annually.

The fall of Constantinople
Mussolini gradually dismantled the institutions of democratic government and in 1925 made himself dictator, taking the title 'Il Duce'. He set about attempting to re-establish Italy as a great European power. The regime was held together by strong state control and Mussolini's cult of personality. Mussolini tried to transform the country's economy along fascist ideology, at least on paper. Mussolini banned all political parties and curtailed personal liberties, thus forming a dictatorship. These actions attracted international attention and eventually inspired similar dictatorships such as Nazi Germany and Francoist Spain
