The British Army historically included many units from what are now separate Commonwealth realm. When the English Empire was established in North America, Bermuda, and the West Indies in the early 17th century there was no standing English Army, only the Militia, Yeomanry, and Royal bodyguards, of which the Militia, as the primary home-defence force, was immediately extended to the colonies. Colonial militias defended colonies single-handedly at first against indigenous peoples and European competitors. Once the standing English Army, later the British Army, came into existence and began to garrison the colonies, the colonial militias fought side by side with it in a number of wars, including the Seven Years' War. Some of the colonial militias rebelled during the American War of Independence. The militia fought alongside the regular British Army (and native allies) in defending British North America from their former countrymen during the War of 1812.
