Myles Standish was elected the first commander of the militia of Plymouth Colony.

Myles Standish was an English military officer and colonist. He was hired as military adviser for Plymouth Colony in present-day Massachusetts, United States by the Pilgrims. Standish accompanied the Pilgrims on the ship Mayflower and played a leading role in the administration and defense of Plymouth Colony from its foundation in 1620. On February 17, 1621, the Plymouth Colony militia elected him as its first commander and continued to re-elect him to that position for the remainder of his life. Standish served at various times as an agent of Plymouth Colony on a return trip to England, as assistant governor of the colony, and as its treasurer.

A militia is a military or paramilitary force that comprises civilian members, as opposed to a professional standing army of regular, full-time military personnel. Militias may be raised in times of need to support regular troops or serve as a pool of available manpower for regular forces to draw from.

Plymouth Colony was the first permanent English colony in New England from 1620 and the third permanent English colony in America, after Newfoundland and the Jamestown Colony. It was settled by the passengers on the Mayflower at a location that had previously been surveyed and named by Captain John Smith. The settlement served as the capital of the colony and developed as the town of Plymouth, Massachusetts. At its height, Plymouth Colony occupied most of what is now the southeastern portion of Massachusetts. Many of the people and events surrounding Plymouth Colony have become part of American folklore, including the American tradition of Thanksgiving and the monument of Plymouth Rock.
