context_page_description: The recorded history of Scotland begins with the arrival of the Roman Empire in the 1st century, when the province of Britannia reached as far north as the Antonine Wall. North of this was Caledonia, inhabited by the Picti, whose uprisings forced Rome's legions back to Hadrian's Wall. As Rome finally withdrew from Britain, Gaelic raiders called the Scoti began colonising Western Scotland and Wales. Prior to Roman times, prehistoric Scotland entered the Neolithic Era about 4000 BC, the Bronze Age about 2000 BC, and the Iron Age around 700 BC.
  The Gaelic kingdom of Dál Riata was founded on the west coast of Scotland in the 6th century. In the following century, Irish missionaries introduced the previously pagan Picts to Celtic Christianity. Following England's Gregorian mission, the Pictish king Nechtan chose to abolish most Celtic practices in favour of the Roman rite, restricting Gaelic influence on his kingdom and avoiding war with Anglian Northumbria. Towards the end of the 8th century, the Viking invasions began, forcing the Picts and Gaels to cease their historic hostility to each other and to unite in the 9th century, forming the Kingdom of Scotland.
context_section_description: Scotland's Scapa Flow was the main base for the Royal Navy in the 20th century. As the Cold War intensified in 1961, the United States deployed Polaris ballistic missiles, and submarines, in the Firth of Clyde's Holy Loch. Public protests from CND campaigners proved futile. The Royal Navy successfully convinced the government to allow the base because it wanted its own Polaris submarines, and it obtained them in 1963. The RN's nuclear submarine base opened with four Resolution-class Polaris submarines at the expanded Faslane Naval Base on the Gare Loch. The first patrol of a Trident-armed submarine occurred in 1994, although the US base was closed at the end of the Cold War.
