On July 19, 1608, preparations commence for the plantation of six Ulster counties of Armagh, Cavan, Coleraine, Donegal, Fermanagh, and Tyrone.

The Plantation of Ulster is the organised colonisation, or plantation, of the Irish province of Ulster by people from Great Britain during the reign of King James I. Most of the settlers, or planters, come from southern Scotland and northern England. Their culture differs from that of the native Irish. Small privately funded plantations by wealthy landowners begin in 1606, while the official plantation begins in 1609. Most of the colonised land had been confiscated from the native Gaelic chiefs, several of whom had fled Ireland for mainland Europe in 1607 following the Nine Years’ War against English rule. The official plantation comprises an estimated half a million acres of arable land in counties Armagh, Cavan, Fermanagh, Tyrone, Donegal, and Coleraine. Land in counties Antrim, Down, and Monaghan is privately colonised with the king’s support.

Among those involved in planning and overseeing the plantation are King James, the Lord Deputy of Ireland, Arthur Chichester, and the Attorney-General for Ireland, John Davies. They see the plantation as a means of controlling, anglicising, and “civilising” Ulster. The province is almost wholly Gaelic, Catholic, and rural and has been the region most resistant to English control. The plantation is also meant to sever Gaelic Ulster’s links with the Gaelic Highlands of Scotland. The colonists, or “British tenants,” are required to be English-speaking, Protestant and loyal to the king. Some of the undertakers and settlers, however, are Catholic. The Scottish settlers are mostly Presbyterian Lowlanders and the English mostly Anglican Northerners. Although some “loyal” natives are granted land, the native Irish reaction to the plantation is generally hostile, and native writers bewail what they see as the decline of Gaelic society and the influx of foreigners.

The Plantation of Ulster is the biggest of the Plantations of Ireland. It leads to the founding of many of Ulster’s towns and creates a lasting Ulster Protestant community in the province with ties to Britain. It also results in many of the native Irish nobility losing their land and leads to centuries of ethnic and sectarian animosity, which at times spills into conflict, notably in the Irish Rebellion of 1641 and, more recently, the Troubles.
