The document summarizes the conflict in Northern Ireland from 1916-1999. It began with English invasion of Ireland in the 1100s and imposition of penal laws against Irish Catholics by the 1600s. Oliver Cromwell's invasion in 1649 intensified oppression of Catholics. The Great Potato Famine of 1845 killed over 1 million Irish and Catholic uprisings continued. The Easter Rising of 1916 launched the Irish war for independence. The Anglo-Irish Treaty of 1921 partitioned Ireland, creating Northern Ireland. Conflict escalated in the late 1960s, culminating in Bloody Sunday in 1972. Peace talks in the 1990s led to the 1998 Good Friday Agreement, establishing power sharing between Catholics and Protestants.
