The Ulster Scots (Ulster-Scots: Ulstèr-Scotch; ) are an ethnic group in Ireland, found mostly in the Ulster region and to a lesser extent in the rest of Ireland. Their ancestors were mostly Protestant Lowland Scottish people, many being from the "Border Reivers" culture. These people migrated to Ireland in large numbers both as a result of the government-sanctioned Plantation of Ulster, a planned process of colonisation which took place under the auspices of James VI of Scotland and James I of England on land confiscated from members of the Gaelic nobility of Ireland who fled Ulster and as part of a larger migration or unofficial settlement.
