One of the first written historical record for Massachusetts is the "Charter of the Governor and Company of the Massachusetts Bay in New England," written in 1629 by King Charles I of England to establish Massachusetts. This charter established the boundaries of the colony and the general structure of the government overseeing it.
The "Charter of the Governor and Company of the Massachusetts Bay in New England" set the boundaries as 3 miles north of the Merrimack River and 3 miles south of the Charles River. It extended the colony from the Atlantic Ocean to the south sea on the west. The charter states that four courts were to be held each year. General Court orders from this period can be found at the Massachusetts Archives, as of 2015.
