Why did britain invade america 1762- 1781?

The British occupation of Manila was an episode in Philippine colonial history when the British Empire occupied the Spanish colonial capital of Manila and the nearby principal port of Cavite for twenty months between 1762 and 1764.

The British wanted to use Manila as an entrepôt for trade in the region, particularly with China.[1] In addition, a ransom for the city was delivered to the Spanish on the basis that the city would not be sacked or burnt.[2] The resistance from the provisional Spanish colonial government established by members of the Royal Audience of Manila led by Lieutenant Governor Simón de Anda y Salazar and their Filipino allies prevented British forces from taking control of territory beyond the neighbouring towns of Manila and Cavite. The British occupation ended as part of the peace settlement of the Seven Years' War.[3]:57
