To which ideology did Benito Mussolini belong?

Benito Amilcare Andrea Mussolini (29 July 1883 – 28 April 1945) was an Italian dictator and journalist who founded and led the National Fascist Party, which is a far-right, authoritarian, ultranationalist political ideology and movement, characterised by a dictatorial leader, centralised autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation or race, and strong regimentation of society and the economy. He was Prime Minister of Italy from the “March on Rome” in 1922 until his deposition in 1943, as well as "Duce" of Italian fascism from the establishment of the Italian Fasces of Combat in 1919 until his summary execution in 1945 by Italian partisans. As dictator of Italy and principal founder of fascism, Mussolini inspired and supported the international spread of fascist movements during the inter-war period. He was one of the main antagonists in WWII.

In late April 1945, with Allied victory imminent, Mussolini and his mistress Clara Petacci attempted to flee to Switzerland, but they were captured by Italian communist partisans and summarily executed on 28 April near Lake Como, and their bodies were strung up by the heels outside a service station in Milan.
