Reformed Presbyterian Church of Ireland
The denomination's roots date back to the 17th-century Plantation of Ulster by Scots Presbyterian settlers. When the Revolution Settlement was entered into in 1690 following the victory of William III in the Williamite War, a minority of Presbyterians refused to subscribe, claiming its failure to specifically recognise the kingship of Jesus Christ was a departure from the Solemn League and Covenant of 1643. These dissenters, or Covenanters, began to hold separate meetings from the mainstream Presbyterians. The Ulster branch of the denomination was dependent on visits from Scottish ministers until 1757.
The church currently has thirty-nine congregations, of which thirty-four are located in Northern Ireland; the remaining five are located in the Republic of Ireland. As of 2011, its total communicant membership is 1,952. The distribution of Reformed Presbyterians accords with the distribution of the Ulster Scots, with most congregations based in Counties Antrim, Londonderry and Down. Several new congregations have, however, been formed recently in the Belfast area.
