People from Northern Ireland are those born in Northern Ireland who, at the time of their birth, have at least one parent who is a British citizen, an Irish citizen, or otherwise entitled to reside in Northern Ireland indefinitely under the Belfast Agreement.
Most Northern Irish people either identify as British, Northern Irish, Irish, or a combination thereof. The 20th century conflict known as The Troubles, which ended in effect in 1999, was primarily caused by tensions between people who had these different identites, and their connections to religion (Anglican protestants and Catholics).
