Input: British Empire
In 1603, James VI, King of Scots, ascended (as James I) to the English throne and in 1604 negotiated the Treaty of London, ending hostilities with Spain. Now at peace with its main rival, English attention shifted from preying on other nations' colonial infrastructures to the business of establishing its own overseas colonies. The British Empire began to take shape during the early 17th century, with the English settlement of North America and the smaller islands of the Caribbean, and the establishment of private companies, most notably the English East India Company, to administer colonies and overseas trade. This period, until the loss of the Thirteen Colonies after the American War of Independence towards the end of the 18th century, has subsequently been referred to by some historians as the "First British Empire".
