After the war began, the provincial congress established a number of committees to manage the rebel activity in the province, starting with the need to supply and arm the nascent Continental Army that besieged Boston after the April 1775 Battles of Lexington and Concord. Pursuant to recommendations of the Second Continental Congress, it in 1775 declared that a quorum of the council (which under the colonial charter acted as governor in the absence of both the governor and lieutenant governor) would be sufficient to make executive decisions. Although the assembly adjourned from time to time, the council remained in continuous session until the new state constitution was introduced in 1780.
