Why was benito mussolini able to seize control in italy?

Benito Mussolini was able to take over because of the problems that occurred in the parliament.In 1922, when communism was starting to invade Italy,Mussolini and his soldiers called the Black Shirts and the Fascist party had marched and overthrown the parliament and thus was asked by King Victor Emmanuel III   to create a party that opts to create a government that is centralized and state controlled.  Mussolini was able to take over Italy.

Ok what subject does the question need tone in? thanx
