What happened in history in 1643?

Answer 1

1603 traditionally marks the point at which 'English' and 'Scottish' history became 'British' history, with the coronation of James VI of Scotland as James I of England. The seventeenth and eighteenth centuries were a period during which the "Three Kingdoms" of Britain (England, Scotland and Wales) along with Ireland became more closely economically, socially, politically and culturally tied together, sometimes peaceably and sometimes through great spasms of violent conflict. Together their regionally oriented economies and societies became linked to the furthest parts of the globe in large part through the growth of London. By the nineteenth century, the sun famously never set on the British Empire and it would be at the center of two World Wars in the twentieth.
