How did george washington play a role in forming the new federal government in 1787?

In 1787, George Washington presided over the Philadelphia Convention that outlined the Constitution of the United States of America and in 1789, he was unanimously elected as the first president of the United States. He tried to create a nation capable of sustaining peace with its neighboring countries. His Proclamation of Neutrality of 1793 served as the basis for avoiding any involvement in foreign conflicts. He supported plans to build a strong central government through the payment of national debt, the application of an effective tax system and the creation of a national bank. Washington avoided the war and maintained a decade of peace with Britain with the signing of the Jay Treaty in 1795, despite intense opposition from the Democratic-Republican Party. Although he never officially joined the Federalist Party, he supported his program. His two periods of government established many policies and traditions that exist to this day.
