Political violence among rival partisans has been a deadly and destabilizing force throughout history and across the globe. It has claimed countless lives, deepened social divisions and even led to the collapse of democratic systems.
In recent history, political violence and its deadly consequences were seen in Italy after World War I when thousands of fascist supporters marched on Rome, the capital, threatening to overthrow the government unless Benito Mussolini was appointed prime minister. That kind of violence and its effects were also seen in 1930s Germany, where Adolf Hitler suppressed opposition and suspended civil liberties amid widespread unrest and factional violence.
