Conflict between Britain and France.

The Northwest Indian War, also known by other names, was an armed conflict for control of the Northwest Territory fought between the United States and a united group of Native American nations known today as the Northwestern Confederacy.

The Indian Army, also called the British Indian Army, was involved in World War I as part of the British Empire.

The Indian Army during World War II, a British force also referred to as the British Indian Army, began the war, in 1939, numbering just under 200,000 men.

Prior to World War II, the Indian Ocean was an important maritime trade route between European nations and their colonial territories in East Africa, the Arabian Peninsula, British India, Indochina, the East Indies (Indonesia), and Australia for a long time.
