Thomas Dudley, English-American soldier and politician, 3rd Governor of the Massachusetts Bay Colony (died 1653)

Thomas Dudley was a New England colonial magistrate who served several terms as governor of the Massachusetts Bay Colony. Dudley was the chief founder of Newtowne, later Cambridge, Massachusetts, and built the town's first home. He provided land and funds to establish the Roxbury Latin School and signed Harvard College's new charter during his 1650 term as governor. Dudley was a devout Puritan who opposed religious views not conforming with his. In this, he was more rigid than other early Massachusetts leaders like John Winthrop, but less confrontational than John Endecott.

The territory of the Commonwealth of Massachusetts, one of the fifty United States, was settled in the 17th century by several different English colonies. The territories claimed or administered by these colonies encompassed a much larger area than that of the modern state, and at times included areas that are now within the jurisdiction of other New England states or of the Canadian provinces of New Brunswick and Nova Scotia. Some colonial land claims extended all the way to the Pacific Ocean.
