Who was the first president of the United States?

The first president of the United States was George Washington, who served from April 30, 1789, to March 4, 1797. He played a critical role in the founding of the nation, leading the Continental Army to victory during the American Revolutionary War and presiding over the Constitutional Convention in 1787. Washington was unanimously elected as president and set many precedents for the office, including the establishment of a cabinet and the tradition of serving only two terms, which influenced future presidents. His leadership and character earned him the title "Father of His Country," solidifying his legacy in American history.
