Thus, in a period of a little less than half a century, the whole of the American coast had been acquired by, and was to a large degree under the dominion of, five European nations. In 1655 the Spaniards held the peninsula of Florida; the French were in possession of, or at least claimed the right to, what are now the two Carolinas; the Dutch held Manhattan Island, New Jersey, a narrow strip running along the west bank of the Hudson, and a portion of Long Island; the Swedes were established (soon to be deprived of it) in what is now Delaware, and a part of what is now Pennsylvania, along the Delaware River; while the English possessions far exceeded those of all the others put together, including as they did nearly the whole of Virginia, a large share of Maryland, all of New England, and the greater part of Long Island. [Sidenote: William Penn.] In the year 1681 all the Dutch possessions had been added to the dominion of the English in America; and it was in this year that William Penn, having received a grant of a large tract of land in what is now Pennsylvania, sent out a colony, which settled on his grant. The next year he came in person, assumed the governorship of the colony, founded Philadelphia, and made his famous treaties with the Indians. At the close of the seventeenth century the English dominion comprised the whole coast, from Canada to the Carolinas; and it may be fairly said that when the eighteenth century opened, the era of colonization had reached its culmination, English civilization was indelibly stamped on, and firmly planted in, the new continent. The crystallizing process of a new and mighty nation had begun and was in rapid progress. IV. THE COLONIAL ERA. [Sidenote: England's Acquirements.] The Colonial Era, intervening between the permanent colonization of the Atlantic coast and the momentous time when the colonies united to assert their independence, may be said to have been comprised within a period of a little more than a century. In 1664 England had acquired possession of the whole colonized territory from the Kennebec to the southern boundary of South Carolina. Georgia was still unsettled, and remained to be colonized some sixty years after by that good and gallant General Oglethorpe, who forbade slavery to be introduced into the province, and prohibited the sale of rum within its limits. Florida was still held by the Spanish, the only continental power which then had a foothold on the Atlantic border of what is now the United States. [Sidenote: Colonial Progress.]
