The Irish Question refers to the complex political and social conflict in Ireland that dates back to the 12th century when England imposed a feudal system, granting lands to English lords while Irish laborers lived in poverty. This led to rebellions by Irish Catholics against English and Protestant domination. The 1800 Act of Union merged Ireland and Britain but tensions remained between nationalists and unionists. Famines in the 1840s exacerbated issues, and rebellions continued through the early 20th century. The island was eventually partitioned into Northern Ireland and Southern Ireland, but conflict continued in Northern Ireland through the late 20th century before the Good Friday Agreement established power sharing in 1998.
