The defeat of New France disturbed the alliances between First Nations groups and the French that had lasted for over two hundred years. With the British now occupying French forts across the territory, new settlers were arriving in greater numbers and encroaching on First Nations lands used for hunting. Some First Nations groups continued fighting the British and American settlers to keep them out of their traditional territories. Pontiac, an Ottawa leader, organized an indigenous coalition to resist the British occupation in the 1760s after the fall of New France.
