During the 1760s and 1770s, relations between the Thirteen Colonies and Britain became increasingly strained, primarily because of resentment of the British Parliament's ability to tax American colonists without their consent. Disagreement turned to violence and in 1775 the American War of Independence began. The following year, the colonists declared the independence of the United States and with economic and naval assistance from France, would go on to win the war in 1783. The Treaties of Versailles were signed, also ending war with the French and Spanish. The Fourth Anglo-Dutch War ended the following year.
