James Stewart, 1st Earl of Moray was a member of the House of Stewart as the illegitimate son of King James V of Scotland. At times a supporter of his half-sister Mary, Queen of Scots, he was the regent of Scotland for his half-nephew, the infant King James VI, from 1567 until his assassination in 1570. He was the first head of government to be assassinated with a firearm.

James VI and I was King of Scotland as James VI from 24 July 1567 and King of England and Ireland as James I from the union of the Scottish and English crowns on 24 March 1603 until his death in 1625. Although he long tried to get both countries to adopt a closer political union, the kingdoms of Scotland and England remained sovereign states, with their own parliaments, judiciaries, and laws, ruled by James in personal union. He was the longest-reigning monarch of the Kingdom of Scotland.
