The Fourth Anglo-Dutch War (1780-1784) was a conflict between the Kingdom of Great Britain and the United Provinces of the Netherlands. It arose from tensions over trade and maritime rights, particularly as the Dutch supported the American colonies during the American Revolutionary War. The war saw naval battles and blockades, impacting both nations' economies. The conflict ended with the signing of the Treaty of Paris in 1784, which restored peace but did not resolve underlying trade disputes. The war marked a decline in Dutch naval power and solidified Britain's dominance at sea, influencing future international relations in Europe.
