History
People lived at Mount Sandel near Coleraine around 9,000 years ago, among the earliest known settlers in Ireland. Navan Fort near Armagh was the ancient royal site of Ulster, the setting of the Ulster Cycle of heroic tales, and in the 5th century St Patrick made Armagh the centre of Irish Christianity; he is traditionally said to be buried at Downpatrick. The Normans built Carrickfergus Castle in the late 12th century, but Gaelic lords such as the O'Neills held most of Ulster until the Nine Years' War and the Flight of the Earls in 1607.
The Plantation of Ulster from 1609 settled English and Scottish Protestants on confiscated land, and London's livery companies walled Derry, renaming it Londonderry. The Catholic rising of 1641 and the Siege of Derry of 1688–89, when apprentice boys shut the gates against James II's army, became lasting symbols on each side.
In the 19th century Belfast grew into an industrial city of linen mills, ropeworks and the Harland and Wolff shipyard, which built the Titanic. When Ireland was partitioned in 1921 the six counties stayed in the UK with their own parliament, later housed at Stormont. The civil rights movement of 1968, the Battle of the Bogside and Bloody Sunday in Derry in 1972 opened the Troubles, about three decades of conflict that killed around 3,500 people, ended by the 1998 Good Friday Agreement. Power-sharing has collapsed several times since, but was restored in 2024 with Michelle O'Neill as the first nationalist First Minister.
