The Jacobean era was the period in English and Scottish history that coincides
with the reign of James VI of Scotland who also inherited the crown of England in 1603 as James I. The Jacobean era succeeds the Elizabethan era and precedes the Caroline era. The term "Jacobean" is often used for the distinctive styles of Jacobean architecture, visual arts, decorative arts, and literature which characterized that period.
King James I by Mijtens (1621)
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.
