Cowal (Scottish Gaelic: Comhghall) is a rugged peninsula in Argyll and Bute, on the west coast of Scotland. It is connected to the mainland to the north, and is bounded by Loch Fyne to the west, by Loch Long and the Firth of Clyde to the east, and by the Kyles of Bute to the south.
Argyll is the historic county that the Cowal peninsula was within. Inveraray was the county town.
Dál Riata or Dál Riada (also Dalriada) (/dælˈriːədə/) was a Gaelic kingdom that encompassed the western seaboard of Scotland and north-eastern Ireland, on each side of the North Channel. At its height in the 6th and 7th centuries, it covered what is now Argyll ("Coast of the Gaels") in Scotland and part of County Antrim in Northern Ireland. After a period of expansion, Dál Riata eventually became associated with the Gaelic Kingdom of Alba.
In Argyll, it consisted of four main kindreds or tribes, each with their own chief: the Cenél nGabráin (based in Kintyre), the Cenél nÓengusa (based on Islay), the Cenél Loairn (who gave their name to the district of Lorn) and the Cenél Comgaill (who gave their name to Cowal). The hillfort of Dunadd is believed to have been its capital. Other royal forts included Dunollie, Dunaverty and Dunseverick. Within Dál Riata was the important monastery of Iona, which played a key role in the spread of Celtic Christianity throughout northern Britain, and in the development of insular art. Iona was a centre of learning and produced many important manuscripts. Dál Riata had a strong seafaring culture and a large naval fleet.
The Firth of Clyde is the estuary of the River Clyde, on the west coast of Scotland. The Firth has some of the deepest coastal waters of the British Isles and is sheltered from the Atlantic Ocean by the Kintyre Peninsula. The Firth lies between West Dunbartonshire in the north, Argyll and Bute in the west, and Inverclyde, North Ayrshire and South Ayrshire in the east. Kilbrannan Sound is a large arm of the Firth, separating the Kintyre Peninsula from the Isle of Arran. The Kyles of Bute separates the Isle of Bute from the Cowal Peninsula. The Sound of Bute separates the islands of Bute and Arran.
The Highland Boundary Fault crosses the Firth. The Firth also played a vital military role during World War II.
Argyll (/ɑːrˈɡaɪl/; archaically Argyle; Scottish Gaelic: Earra-Ghàidheal, pronounced [ɛrˠə ˈɣɛː.əl̪ˠ]), sometimes called Argyllshire, is a historic county and registration county of western Scotland. The county ceased to be used for local government purposes in 1975 and most of the area now forms part of the Argyll and Bute council area.
Argyll is of ancient origin, and broadly corresponds to the ancient kingdom of Dál Riata less the parts which were in Ireland. Argyll was also a medieval bishopric with its cathedral at Lismore. In medieval times the area was divided into a number of provincial lordships. One of these, covering only the central part of the later county, was called Argyll. It was initially an earldom, elevated to become a dukedom in 1701 with the creation of the Duke of Argyll. Other lordships in the area included Cowal, Kintyre, Knapdale, and Lorn. From at least the 14th century there was a Sheriff of Argyll, whose jurisdiction was gradually extended; from 1633 the shire covered all these five provinces. Shires gradually eclipsed the old provinces in administrative importance, and also became known as counties. Between 1890 and 1975, Argyll had a county council. The county town was historically Inveraray, but from its creation in 1890 the county council was based at Lochgilphead.
The Cenél nÓengusa were a kin group who ruled the island of Islay, and perhaps nearby Colonsay, off the western coast of Scotland in the early Middle Ages.
The Senchus fer n-Alban, a census and genealogy of the kingdom of Dál Riata, lists the Cenél nÓengusa as one of the three kin groups making up the kingdom in Argyll. The others were the Cenél nGabráin of Kintyre and the Cenél Loairn of Lorn. A fourth group, the Cenél Comgaill, of Cowal and the Isle of Bute, later split from the Cenél nGabráin. The Senchus portrays Dál Riata as it existed in the mid-seventh century.
Comgall mac Domangairt was king of Dál Riata in the early 6th century. He was the son of Domangart Réti and grandson of Fergus Mór. The Annals of Ulster report his death in 538, 542 and 545, the Annals of Tigernach in 537.
The Kyles of Bute (Scottish Gaelic: Na Caoil Bhòdach) form a narrow sea channel that separates the northern end of the Isle of Bute from the Cowal Peninsula in Argyll and Bute, on the Scottish mainland. The surrounding hillsides are roughly wooded, and overlooked by rocky tops and areas of moorland.
The Kyles are split into the East and West Kyles. The East Kyle (Scottish Gaelic: An Caol an Ear) runs from Rothesay Bay north west up to the entrance to Loch Riddon. Here at the northern end of the East Kyle are the Burnt Islands and the island of Eilean Dubh. The West Kyle (Scottish Gaelic: An Caol an Iar/An Caol Ceathrach) runs from here southwest, past the village of Tighnabruaich out to the Sound of Bute. The area is a designated National Scenic Area.
