The Loyalists were American colonists who remained loyal to the British Crown during the American Revolutionary War. At the time they were often called Tories, Royalists, or King's Men; Patriots called them "persons inimical to the liberties of America". They were opposed by the Patriots, those who supported the revolution. Prominent Loyalists repeatedly assured the British government that many thousands of loyalists would spring to arms and fight for the crown. The British government acted in expectation of that, especially in the southern campaigns in 1780-81. In practice, the number of loyalists in military service was far lower than expected. Across the new United States, Patriots watched suspected Loyalists very closely, and would not tolerate any organized Loyalist opposition. Many outspoken or militarily active loyalists were forced to flee, especially to their stronghold of New York City.
When their cause was defeated, about 15% of the Loyalists (65,000–70,000 people) fled to other parts of the British Empire, to Britain itself, or to British North America (now Canada). The southern colonists moved mostly to Florida, which had remained loyal to the Crown, and to British Caribbean possessions, often bringing along their slaves. Northern Loyalists largely migrated to Ontario, Quebec, New Brunswick, and Nova Scotia. They called themselves United Empire Loyalists. Most were compensated with Canadian land or British cash distributed through formal claims procedures. Exiled Loyalists received £3 million or about 37% of their losses from the British government. Loyalists who stayed in the U.S. were generally able to retain their property and become American citizens.
Historians have estimated that between 15 and 20 percent of the 2.0 million whites in the colonies in 1775 were Loyalists, or about 300-400,000 men, women and children (however, this figure does not include Black colonists or Native Indians).
