The people of Virginia hailed the Restoration with unaffected joy. Not only did they anticipate that the termination of the long period of civil war and unrest in England would react favorably upon their own prosperity, but they felt that Sir William Berkeley's well known loyalty and his action in proclaiming Charles II immediately after the execution of his father, might assure them the King's especial favor now that he at last had come into undisputed possession of his throne. They were doomed to bitter disappointment, however, for the Restoration brought them only hardship and suffering, discontent and rebellion. No sooner had the royal Government been safely installed than it set to work to perfect and to enforce the colonial policy which in principle had been accepted from the first. The ties which united the colonies with the mother country were strengthened, those which gave them a common interest with foreign nations in so far as possible were snapped. The British empire was to become a unit, closely knit by economic bonds and presenting to all other nations a hostile front. With this in view Parliament passed a series of Navigation Acts, under which the trade of the colonies was regulated for many years to come. It is necessary for us to enquire, therefore, into the effects of these laws upon the tobacco trade, for tobacco, as we have seen, was the key to the prosperity of the colony, and favorable economic conditions alone could make it possible for the newcomer to establish himself as a member of the Virginia yeomanry. If the strict enforcement of the Navigation Acts should bring low prices for tobacco and wipe out the margin of profit for the man who tilled the soil with his own hands, not only would the small planter class not expand, but might actually decline in numbers. There were three main features of the colonial legislation of Parliament during this period, all of them interrelated and all tending toward the one great object of keeping the English plantations for the English. It was provided that the chief colonial products such as tobacco and sugar should be sent only to England or to English colonies, that the colonies should with few exceptions import goods only from British territory, that all products taken to or from any colony should be conveyed only in English vessels manned by crews composed mainly of Englishmen.
