Queen Elizabeth I of England paid a subsidy to King James VI of Scotland from 1586 to 1602. This enabled her to influence James by delaying or deferring payments to his diplomats in London. Records survive of the yearly amounts, and details of the expenditure in some years. A large proportion of the money was spent on the royal wardrobe of James and Anne of Denmark. Some royal expenses were met by Anne of Denmark's dowry, which was known as the "tocher". The regular incomes of the Scottish crown were feudal rents, customs, and "compositions" charged on grants of land. Accounts for royal incomes and payments survive as the exchequer rolls and lord treasurer's accounts and have been published as historical sources.

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.
