At the Constitutional Convention, which convened in May 1787 to address the ineffective and weakening Articles of Confederation, Charles Pinckney, one of the youngest delegates, made major contributions to the content of the United States Constitution. He submitted the Pinckney Draught, one of two plans presented at the Convention, and his plan called for a strong central government with three separate and distinct branches. More than thirty of his provisions were included in the final document, including a legislature consisting of a House and a Senate, the House alone holding the power of impeachment, legislative power to establish post offices, call out the militia, and raise an army and a navy, a single chief executive called the President, the President's duty to inform the legislature of the condition of the nation, the President serving as commander-in-chief of the army and navy, the President's power to convene the legislature under extraordinary conditions, a judicial department to settle matters between states and the federal government, prohibitions on states keeping troops or warships in peacetime, coining money, entering treaties, and establishing tariffs, regulation of interstate and foreign commerce only by Congress, a Citizen Bill of Rights, and the principle that no religious test shall ever be required as a qualification to any office or public trust under the United States. On the Convention's opening day he was one of three delegates appointed to prepare standing rules and orders, he was an active participant in the proceedings, he spoke more than one hundred times during the debates in Philadelphia, and on June 25th he made a forcible case for the unique quality of America and the importance of seeking original solutions for the new United States government.
