It was well for the colonies that this underlying unity of aim existed, for aside from this they were strikingly distinct in character and aspirations. Sparsely settled, strung at intervals along the far-extended Atlantic coast, silhouetted against a stern background of wilderness and mountain range, their sole bond of brotherhood was their common aspiration for liberty, while in all other respects they were unlike in aims and purposes. The spirit of political liberty was strongest in the New England colonies, and these held their own against every effort to rob them of their rights with an unflinching boldness which is worthy of the highest praise, and which set a noble example for the remaining colonists. Next to them in bold opposition to tyranny were the people of the Carolinas, who sturdily resisted an effort to make them the enslaved subjects of a land-holding nobility. In Pennsylvania and Maryland political rights were granted by high-minded proprietors, and in these colonies no struggle for self-government was necessary. Only in Virginia and New York was autocratic rule established, and in both of these it gradually yielded to the steady demand for self-government.
On the other hand, New England, while politically the freest, was religiously the most autocratic. The Puritans, who had crossed the ocean in search of freedom of thought, refused to grant a similar freedom to those who came later, and sought to found a system as intolerant as that from which they had fled. A natural revulsion from their oppressive measures gave rise in Rhode Island to the first government on the face of the earth in which absolute religious liberty was established. Among the more southern colonies, a similar freedom, so far as liberty of Christian worship is concerned, was granted by William Penn and Lord Baltimore. But this freedom was maintained only in Rhode Island and Pennsylvania, religious intolerance being the rule, to a greater or less degree, in all the other colonies; the Puritanism of New England being replaced elsewhere by a Church of England autocracy.
The diversity in political condition, religion, and character of the settlers tended to keep the colonies separate, while a like diversity of commercial interests created jealousies which built up new barriers between them. The unity that might have been looked for between these feeble and remote communities, spread like links of a broken chain far along an ocean coast, had these and other diverse conditions to contend with, and they promised to develop into a series of weak and separate nations rather than into a strong and single commonwealth.
The influences that overcame this tendency to disunion were many and important. We can only glance at them here. They may be divided into two classes, warlike hostility and industrial oppression. The first step towards union was taken in 1643, when four of the New England colonies formed a confederation for defense against the Dutch and Indians. "The United Colonies of New England" constituted in its way a federal republic, the prototype of that of the United States. The second step of importance in this connection was taken in 1754, when a convention was held at Albany to devise measures of defense against the French. Benjamin Franklin proposed a plan of colonial union, which was accepted by the convention. But the jealousy of the colonies prevented its adoption. They had grown into communities of some strength and with a degree of pride in their separate freedom, and were not ready to yield to a central authority. The British Government also opposed it, not wishing to see the colonies gain the strength which would have come to them from political union. As a result, the plan fell to the ground.
The next important influence tending towards union was the oppressive policy of Great Britain. The industries and commerce of the colonies had long been seriously restricted by the measures of the mother-country, and after the war with France an attempt was made to tax the colonists, though they were sternly refused representation in Parliament, the tax-laying body. Community in oppression produced unity in feeling; the colonies joined hands, and in 1765 a congress of their representatives was held in New York, which appealed to the King for their just political rights. Nine years afterwards, in 1774, a second congress was held, brought together by much more imminent common dangers. In the following year a third congress was convened. This continued in session for years, its two most important acts being the Declaration of Independence from Great Britain and the Confederation of the States, the first form of union which the colonies adopted. This Confederation was in no true sense a Union. The jealousies and fears of the colonies made themselves apparent, and the central government was given so little power that it threatened to fall to pieces of its own weight. It could pass laws, but could not make the people obey them. It could incur debts, but could not raise money by taxation to pay them. The States kept nearly all the power to themselves, and each acted almost as if it were an independent nation, while the Congress of the Confederation was left without money and almost without authority.
This state of affairs soon grew intolerable. "We are," said Washington, "one nation to-day, and thirteen to-morrow." Such a union it was impossible to maintain. It was evident that the compact must give way; that there must be one strong government or thirteen weak ones. This last alternative frightened the States. None of them was strong enough to hold its own against foreign governments. They must form a strong union or leave themselves at the mercy of ambitious foes. It was this state of affairs that led to the Constitutional Convention of 1787, by whose wisdom the National Union which has proved so solid a bond was organized. The Constitution made by this body gave rise to the Republic of the United States. A subsequent act, which in 1898 added a number of distant island possessions to our Union, and vastly widened its interests and its importance in the world's councils, made of it a "Greater Republic," a mighty dominion whose possessions extended half round the globe.
While the changes here briefly outlined were taking place, the country was growing with phenomenal rapidity. From all parts of northern and western Europe, and above all from Great Britain, new settlers were crowding to our shores, while the descendants of the original settlers were increasing in numbers. How many people there were here is in doubt, but it is thought that in 1700 there were more than 200,000, in 1750 about 1,100,000, and in 1776 about 2,500,000. The first census, taken in 1790, just after the Federal Union was formed, gave a population of nearly 4,000,000.
A people growing at this rate could not be long confined to the narrow ocean border of the early settlements. A rich and fertile country lay back, extending how far no one knew, and soon there was a movement to the West, which carried the people over the mountains and into the broad plains beyond. A war was fought with France for the possession of the Ohio country. Boone and other bold pioneers led hardy settlers into Kentucky and Tennessee, and George Rogers Clark descended the Ohio and drove the British troops from the northwest territory, gaining that vast region for the new Union.
After the War for Independence the movement westward went on with rapidity. The first settlement in Ohio was made at Marietta in 1788; Cincinnati was founded in 1790; in 1803 St. Louis was a little village of log-cabins; and in 1831 the site of Chicago was occupied by a dozen settlers gathered round Fort Dearborn. But while the cities were thus slow in starting, the country between them was rapidly filling up, the Indians giving way step by step as the vanguard of the great march pressed upon them; here down the Ohio in bullet-proof boats, there across the mountains on foot or in wagons. A great national road stretched westward from Cumberland, Maryland, which in time reached the Mississippi, and over whose broad and solid surface a steady stream of emigrant wagons poured into the great West. At the same time steamboats were beginning to run on the Eastern waters, and soon these were carrying the increasing multitude down the Ohio and the Mississippi into the vast Western realm. Later came the railroad to complete this phase of our history, and provide a means of transportation by whose aid millions could travel with ease where a bare handful had made their way with peril and hardship of old.
Up to 1803 our national domain was bounded on the west by the Mississippi, but in that year the vast territory of Louisiana was purchased from France and the United States was extended to the summit of the Rocky Mountains, its territory being more than doubled in area. Here was a mighty domain for future settlement, across which two daring travelers, Lewis and Clark, journeyed through tribes of Indians never before heard of, not ending their long route until they had passed down the broad Columbia to the waters of the Pacific.
