Who started the Indian war

The Newly acquired United States, battled the British over gaining control of land.

The French and Indian War was the North American conflict in a larger imperial war between Great Britain and France known as the Seven Years' War. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American Revolution.

Or if it's another one then the British took control.
