The Fourth Anglo-Dutch War was a conflict between the Kingdom of Great Britain and the Dutch Republic. The war, contemporary with the War of American Independence, broke out over British and Dutch disagreements on the legality and conduct of Dutch trade with Britain's enemies in that war.
Although the Dutch Republic did not enter into a formal alliance with the United States and their allies, U.S. ambassador John Adams managed to establish diplomatic relations with the Dutch Republic, making it the second European country to diplomatically recognise the Continental Congress in April 1782. In October 1782, a treaty of amity and commerce was concluded as well.
Most of the war consisted of a series of British operations against Dutch colonial economic interests, although British and Dutch naval forces also met once off the Dutch coast. The war ended disastrously for the Dutch and exposed the weakness of the political and economic foundations of the republic.
The war settled the decline of the Dutch Empire and further cemented Great Britain as the leading commercial power.
