American History: The tide of migration that set in toward the shores of North America during the early years of the seventeenth century was but one phase in the restless and eternal movement of mankind upon the surface of the earth. The ancient Greeks flung out their colonies in every direction, westward as far as Gaul, across the Mediterranean, and eastward into Asia Minor, perhaps to the very confines of India. Of this great sweep of races and empires the settlement of America was merely a part. And it was, moreover, only one aspect of the expansion which finally carried the peoples, the institutions, and the trade of Europe to the very ends of the earth.
In one vital point, it must be noted in American History, American colonization differed from that of the ancients. The Greeks usually carried with them affection for the government they left behind and sacred fire from the altar of the parent city; but thousands of the immigrants who came to America disliked the state and disowned the church of the mother country. They established compacts of government for themselves and set up altars of their own. They sought not only new soil to till but also political and religious liberty for themselves and their children.
