They came, most of them, from the ignorant laboring class of England, and were incapable, even after the expiration of their term of indenture, of taking an intelligent part in governmental affairs. It is true that many free families of humble means came to the colony in this period, but their numbers were not great enough to counterbalance the power of the leading planters. These families formed the nucleus of what later became an energetic middle class, but not until their ranks were recruited by thousands of servants, did they develop into a really formidable body. It was the Commonwealth Period that gave to the middle class its first taste of power. After the surrender of the colony to Parliament, the House of Burgesses was made the ruling body in Virginia, in imitation of conditions in England. Since the Burgesses were the representatives of the common people, it might naturally be inferred that the rich planters would be excluded from any share in the government. Such, however, was not the case. By a conveniently rapid change of front the most prominent men of the colony retained much of their old influence, and the rabble, lacking leaders of ability, were forced to elect them to places of trust and responsibility. But the Commonwealth Period helped to organize the middle class, to give it a sense of unity and a desire for a share in the government. At the time of Bacon's Rebellion it had grown in numbers and strength, despite the oppression of the Restoration Period, and showed, in a way never to be forgotten, that it would no longer submit passively to tyranny or injustice.
