Halifax was established in 1749, violating a treaty and tiggering Father Le Loutre's War. This conflict pitted the British and New England colonists against the French and the Mi'kmaq nation, and would lead to several devastating attacks, including the Dartmouth Massacre of 1751. Eventually, it led to British dominance in the region and the expulsion of the Acadians.
During the Seven Years War, Halifax became a naval base, which would prove crucial in the Siege of Louisburg. It became the headquarters for the Royal Navy in North America and would also play an important strategic role during the American Revolution.
The conflict with the Mi'kmaq finally ended in 1761, with a series of peace treaties that culminated in the "Burying of the Hatchet Ceremony".
