THE CONSTITUTIONAL CONVENTION.--Congress issued the call early in 1787, and delegates from twelve states [19] met at Philadelphia and framed the Constitution of the United States. Washington was made president of the convention, and among the members were many of the ablest men of the time. [20] [Illustration: INVITATION SENT BY WASHINGTON, AS PRESIDENT OF THE CONVENTION.

The small states wanted a Congress of one house, and equality of state representation. The great states wanted Historical a Congress of two houses, with representation in proportion to population. This difference of opinion was so serious that a compromise was necessary, and it was agreed that in one branch (House of Representatives) the people should be represented, and in the other (Senate) the states. The question then arose whether slaves should be counted as population. The Southern delegates said yes; the Northern, no. It was finally agreed that direct taxes and representatives should be apportioned according to population, and that three fifths of the slaves should be counted as population. This was the second compromise. The convention agreed that Congress should regulate foreign commerce. But the Southern members objected that by means of this power Congress might pass navigation acts limiting trade to American ships, which might raise freights on exports from the South. Many Northern members, on the other hand, wanted the slave trade stopped. These two matters were therefore made the basis of another compromise, by which Congress could pass navigation acts, but could not prohibit the slave trade before 1808. THE CONSTITUTION RATIFIED.--When the convention had finished its work (September 17, 1787), the Constitution [21] was sent to the old (Continental) Congress, which referred it to the states, and the states, one by one, called on the people to elect; delegates to conventions to ratify or reject the new plan of government. In a few states it was accepted without any demand for changes. In others it was vigorously opposed as likely to set up too strong a government. In Massachusetts, New York, and Virginia adoption was long in doubt. [22] By July, 1788, eleven states had ratified, and the Constitution was in force as to these States. [23] ESTABLISHMENT OF THE NEW GOVERNMENT.--The Continental Congress then appointed the first Wednesday in January, 1789, as the day on which electors of President should be chosen in the eleven states; the first Wednesday in February as the day on which the electors should meet and vote for President; and the first Wednesday in March (which happened to be the 4th of March) as the day when the new Congress should assemble at New York and canvass the vote for President.
