Before his untimely death, Collins took part in many major events in Irish history. He started out in the 1916 Easter Rising and was to later become one of the driving forces behind the War of Independence. He set up a spy network in Dublin, and "the Squad", a group which assassinated british spies. He was one of the revolutionary leaders who signed the Anglo-Irish treaty of 1921. After the Irish civil war ended, Collins was ambushed by a group of irregulars(anti-treaty ira) and shot dead. Today, he is still remembered as one of Irelands greatest leaders to date.
