In 1617 or 1618, however, when the liberals were in full control of the Company, it was decided to grant the colonists the privilege of a parliament.[137] In April, 1618, Lord De la Warr sailed for Virginia to reassume active control of affairs there, bringing with him instructions to establish a new form of government. What this government was to have been is not known, but it was designed by Sir Edwin Sandys, and beyond doubt, was liberal in form.[138] Possibly it was a duplicate of that established the next year by Governor Yeardley. Most unfortunately, Lord De la Warr, whose health had been shattered by his first visit to Virginia, died during the voyage across the Atlantic, and it became necessary to continue the old constitution until the Company could appoint a successor.[139] In November, 1618, George Yeardley was chosen Governor-General of Virginia, and was intrusted with several documents by whose authority he was to establish representative government in the colony.[140] These papers, which became known as the Virginia Magna Charta, were the very corner-stone of liberty in the colony and in all America. Their importance can hardly be exaggerated, for they instituted the first representative assembly of the New World, and established a government which proved a bulwark against royal prerogative for a century and a half. Governor Yeardley sailed from England January, 1619, and reached Virginia on the 29th of April. After some weeks of preparation, he issued a general proclamation setting in operation the Company's orders. It was decreed, "that all those who were resident here before the departure of Sir Thomas Dale should be freed and acquitted from such publique services and labors which formerly they suffered, and that those cruel laws by which we had so long been governed were now abrogated, and that now we were to be governed by those free laws which his Majesty's subjects live under in Englande.... And that they might have a hand in the governing of themselves, it was granted that a General Assembly should be held yearly once, whereat were to be present the Governor and Counsell, with two Burgesses from each plantation freely to be elected by the inhabitants thereof; this Assembly to have power to make and ordaine whatsoever lawes and orders should by them be thought good and proffittable for our subsistence."[141]
