Common law
The common lawso named because it was "common" to all the king's courts across Englandoriginated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066. The British Empire spread the English legal system to its historical colonies, many of which retain the common law system today. These "common law systems" are legal systems that give great precedential weight to common law, and to the style of reasoning inherited from the English legal system.
Plymouth General Court
The General Court of the Colony of New Plymouth was founded in 1620 when the Pilgrims came to New England, and the General Court served as the colony's legislature and judicial court. In 1636 the Court created North America's first written legal code with a set of statutes including a rudimentary bill of rights protecting traditional liberties such as the right to a jury trial. The early law of the colony was based roughly on English common law and Mosaic law, but the judicial structure resembled local manor and borough courts in England rather than the higher King's Court, which created the common law. The early Plymouth General Court met within the fort on Burial Hill near Cole's Hill in downtown Plymouth.
