The French residents of Acadia are given one year to declare allegiance to Britain or leave Nova Scotia, Canada.
French settlers in Acadia are forced to choose between British allegiance or exile in Nova Scotia, marking a pivotal moment in North American colonial history.
In 1713, following Britain's victory in the War of the Spanish Succession, the Treaty of Utrecht transferred control of Acadia from France to Britain. The British authorities demanded that French-speaking residents swear an oath of allegiance to the Crown within one year. Those who refused faced exile from their homes. This edict set the stage for the Grand Dérangement, the mass deportation of Acadians. Many were forced to leave their farms and communities behind. The event reshaped the demographic and cultural landscape of Nova Scotia. It remains a defining episode in the history of Canadian colonial relations.
