Some of the Acadians deported from Canada's Maritimes in 1755 settled in Louisiana where they formed the Cajun culture. Why were they deported?

The Acadians had lived on Nova Scotia’s territory since the founding of Port-Royal in 1604. With their friends and allies the Mi' kmaq, they felt secure, even when sovereignty over their land passed to Britain after 1713. In 1730 the British authorities persuaded the Acadians to swear that they will be neutral in case a conflict between Britain and France occurs. But over the years the position of the Acadians in Nova Scotia became more and more uncertain. While previous British governors had been conciliative towards the Acadians, Governor Charles Lawrence was prepared to take drastic action. He considered the Acadian question to be a military matter. In 1755, After Fort Beauséjour fell to the English forces, Lawrence noted that there were enough people in Acadian militia to profess their neutrality.

In meetings with Acadians in July 1755 in Halifax, Lawrence pressed the delegates to take an unqualified oath of allegiance to Britain. When they refused, he imprisoned them and gave the fateful order for deportation. Soldiers rounding up terrified civilians, expelling them from their land, burning their homes and crops. That was Deportation of the Acadians.
