Going into force in 1789, this constitution reorganized the government into a federation administered by three equal branches (executive, judicial and legislative), on the principle of creating salutary checks and balances. George Washington, who had led the Continental Army to victory and then willingly relinquished power, was the first president elected under the new constitution. The Bill of Rights, forbidding federal restriction of personal freedoms and guaranteeing a range of legal protections, was adopted in 1791.
