Constitutional Convention, 1787
The Constitutional Convention met in Philadelphia between May and September of 1787 to address the problems of the weak central government under the Articles of Confederation. The fifty-five delegates presented their ideas, argued, and compromised over slavery, representation, states’ rights, tariffs, and other divisive issues. They emerged with a new document, the US Constitution, that defined a strong national government with three branches to establish checks and balances. This new government also brought the individual states together as one nation. Finally, they ensured a flexible document that could be amended. The Constitution went into effect in 1789 and has served as the basis of the US government ever since.
