The last invasion of Britain occurred in 1780 during the American Revolutionary War. A group of loyalists, known as the British Army, attempted to capture the coastal town of Charleston, South Carolina. This invasion was part of a larger conflict between the American colonies and Great Britain, which sought to maintain control over its territories. The most notable invasion before this was the Norman Conquest in 1066, led by William the Conqueror. However, the 1780 attempt was significant as it marked the final military invasion of British soil, highlighting the shifting power dynamics of the time as the colonies sought independence.
