The form of Massachusetts government is provided by the Constitution of the Commonwealth. The legislative power is exercised by the bicameral General Court, composed of the Senate and House of Representatives. The executive power generally is exercised by the Governor, along with other independently elected officers, the Attorney General, Secretary of the Commonwealth, and Auditor. The judicial power is reposed in the Supreme Judicial Court, which superintends the entire system of courts. Cities and towns also act through local governmental bodies that possess only the authority granted to them by the Commonwealth over local issues, including limited home rule authority. Most county governments were abolished in the 1990s and 2000s, although a handful remain.
The capital of Massachusetts is Boston. The seat of power is Beacon Hill, which is home to the legislative and executive branches. The Supreme Judicial Court occupies nearby Pemberton Hill.
There are 151 departments or agencies in Massachusetts, and over 700 independent boards and commissions. The Governor exercises direct control over many of the largest agencies, but only indirect control over independent entities through appointments.
