The Right to Keep and Bear Arms (Senate report):
...The right to keep and bear arms as a part of English and American law antedates not only the Constitution, but also the discovery of firearms. Under the laws of Alfred the Great, whose reign began in 872 A.D., all English citizens from the nobility to the peasants were obliged to privately purchase weapons and be available for military duty. This was in sharp contrast to the feudal system as it evolved in Europe, under which armament and military duties were concentrated in the nobility...
...In the colonies, availability of hunting and need for defense led to armament statutes comparable to those of the early Saxon times. In 1623, Virginia forbade its colonists to travel unless the were "well armed"; in 1631 it required colonists to engage in target practice on Sunday and "to bring their peeces to church." In 1658 it required every householder to have a functioning firearm within his house and in 1673 its laws provided that a citizen who claimed he was too poor to purchase a firearm would have one purchased for him by the government, which would then require him to pay a reasonable price when able to do so. In Massachusetts, the first session of the legislature ordered that not only freemen, but also indentured servants own firearms and in 1644 it imposed a stern 6 shilling fine upon any citizen who was not armed...
...In the Militia Act of 1792, the second Congress defined "militia of the United States" to include almost every free adult male in the United States. These persons were obligated by law to possess a firearm and a minimum supply of ammunition and military equipment. This statute, incidentally, remained in effect into the early years of the [20th] century as a legal requirement of gun ownership for most of the population of the United States...
