Of the other colonies in 1750, the two Carolinas and New Jersey were rather more than eighty years old, while Pennsylvania had been settled scarcely seventy years. But the growth of these younger colonies had been rapid, especially in the case of Pennsylvania and North Carolina, which in populousness ranked third and fourth among the thirteen. This rapid increase was mainly due to a large immigration from Europe kept up during the first half of the eighteenth century, so that a large proportion of the people had either been born in Europe, or were the children of people born in Europe. In 1750 these colonies had not had time enough to become so intensely American as Virginia and the New England colonies. In Georgia, which had been settled only seventeen years, people had had barely time to get used to this new home on the wild frontier. The population of these younger colonies was very much mixed. In South Carolina, as in New York, probably less than half were English. In both Carolinas there were a great many Huguenots from France, and immigrants from Germany and Scotland and the north of Ireland were still pouring in. Pennsylvania had many Germans and Irish, and settlers from other parts of Europe, besides its English Quakers. With all this diversity of race there was a great diversity of opinions about political questions, as about other matters. [Sidenote: Why Massachusetts and Virginia took the lead.] We are now beginning to see why it was that Massachusetts and Virginia took the lead in bringing on the revolutionary war. Not only were these two the largest colonies, but their people had become much more thoroughly welded together in their thoughts and habits and associations than was as yet possible with the people of the younger colonies. When the revolutionary war came, there were very few Tories in the New England colonies and very few in Virginia; but there were a great many in New York and Pennsylvania and the two Carolinas, so that the action of these commonwealths was often slow and undecided, and sometimes there was bitter and bloody fighting between men of opposite opinions, especially in New York and South Carolina.
