Earl of Carrick or Mormaer of Carrick is the title applied to the ruler of Carrick (now southern Ayrshire), subsequently part of the Peerage of Scotland. The position came to be strongly associated with the Scottish crown when Robert the Bruce, who had inherited it from his maternal kin, became King of the Scots in the early 14th century. Since the 15th century the title of 'Earl of Carrick' has automatically been held by the heir to the throne, meaning Prince Charles is the current Earl.
The earldom emerged in 1186, out of the old Lordship of Galloway, which had previously encompassed all of what is now known as Galloway as well as the southern part of Ayrshire. Though the Lords of Galloway recognised the King of Scots as their overlord, their lordship was effectively a separate kingdom, and had its own laws. The first Lord recorded is Fergus, who died in 1161 leaving two sons: Uchtred and Gille Brigte (Gilbert). As was the custom then, the two brothers shared the lordship and the lands between them. In 1174, they joined with King William the Lion in his invasion of Northumberland. However, after King William was taken prisoner by the English, the Galwegians broke into rebellion. Uchtred, who remained loyal to the Scottish king, was savagely murdered by Gille Brigte's son Máel Coluim, and Gille Brigte took control of the entirety of Galloway. In 1175, King William was restored to liberty, and he marched an army into Galloway to bring justice upon Gille Brigte. However, he seems to have contented himself with exacting a fine, leaving Gille Brigte to go unharmed.
Earl of Carrick, in the barony of Iffa and Offa East, County Tipperary, is a title in the Peerage of Ireland.
The title was first created in 1315 for Sir Edmund Butler, Justiciar of Ireland, by King Edward II. The title is linked to the manor of Karryk Mac Gryffin (the modern town of Carrick-on-Suir) in the barony of Iffa and Offa East, County Tipperary. Edmund was the father of James Butler, 1st Earl of Ormond and John Butler of Clonamicklon. However, upon his death in 1321 the earldom was not inherited by his son and heir. Later, with the second creation of the title, it was bestowed on the descendants of his second son, John, who became Viscounts Ikerrin and Earls of Carrick. Sir Edmund Butler had distinguished himself in the fight against the Bruce invasion of Ireland.
In 1629 Lieutenant-General Sir Pierce Butler was raised to the Peerage of Ireland as Viscount Ikerrin. He was the descendant of John Butler of Clonamicklon, the second son of Edmund Butler, Earl of Carrick. The Viscount's great-great-grandson, the 4th Viscount, sat in the Irish Parliament of James II and was outlawed in 1689 after the accession of William III and Mary II. However, the outlawry was annulled in 1698 and he was able to take his seat in the Irish House of Lords. Lord Ikerrin later achieved the military rank of Brigadier-General.
