In May 1787, men from all over the United States arrived in Philadelphia, Pennsylvania, on serious business. Just eleven years earlier, colonial leaders had met in Philadelphia to declare their independence from Great Britain. But now the young country was in trouble. The U.S. government was weak, and its guiding document―the Articles of Confederation―was failing. Throughout the summer of 1787, state representatives and leaders argued, shouted, and wrote and rewrote articles. By September, they had produced a new document, the U.S. Constitution. The Convention became a turning point in American history. But what were the new country’s problems? Who came up with the solutions? How did the states work out disagreements to create a new system of government? Discover the facts about the 1787 Convention and the writing of the Constitution.

In June 1776, colonial delegates to the Continental Congress began writing a document to set up a new country―with a government independent from Britain. The Articles of Confederation created a limited centralized government, with states keeping most of the power. After sixteen months of debate, delegates finally passed the Articles on November 15, 1777. But afterward, many conflicts arose. It became clear that the country needed―but also feared―a stronger central government. The states sent delegates to another meeting called the Constitutional Convention, out of which came the U.S. Constitution. So who attended the Continental Congress? How did the Articles of Confederation hold the country together during the Revolutionary War? What was Shay's Rebellion? Discover the facts about the Articles of Confederation and learn how this document influenced the formation of the U.S. government.
