The Second Anglo-Dutch War (1665-1667) was a conflict between the Kingdom of England and the Dutch Republic. It arose from competition over trade and colonial dominance, particularly in the lucrative spice and sugar markets. The war featured significant naval battles, including the famous Battle of Lowestoft, where the English fleet, led by Admiral Robert Blake, achieved a decisive victory. The war ended with the Treaty of Breda in 1667, which restored peace and allowed both nations to retain some of their territories. The conflict highlighted the growing rivalry between the two maritime powers and set the stage for future confrontations, including the Third Anglo-Dutch War.
