To answer your questions, the French and Indian war started in the year 1754 and it started because of an already existing imperial war between France and the Great Britain (This is called the Seven Years War). This war, however, ended in 1763 through the Treaty of Paris. 

Take note that the reason why the French and Indian War started was because of the struggle for power and control in North America.
