The Anglo–Spanish War was a military conflict fought between Britain and Spain as part of the Seven Years' War. It lasted from January 1762 until February 1763 when the Treaty of Paris brought it to an end.
For most of the Seven Years' War, Spain remained neutral, turning down offers from the Kingdom of France to join the war on their side, but during the war's latter stages, the newly crowned King of Spain, Charles III, had signalled his intention to enter the war on the side of the French. After Charles had signed the family compact with France and seized British shipping alongside expelling British merchants, the British declared war on Spain. In August 1762, a British expedition captured Havana, then a month later the British took Manila. The loss of both the capitals of the Spanish West Indies and the Spanish East Indies represented a blow to Spanish prestige. Between May and November, three major Franco-Spanish invasions of Portugal were defeated and they were forced to withdraw with heavy losses inflicted by the Portuguese.
