The United States Congress, a testament to the enduring principles of representative democracy, is a historic institution. Comprising of two chambers—the U.S. Senate and the U.S. House of Representatives, it was established by Article I of the U.S. Constitution. . This bicameral legislature, designed during the Constitutional Convention of 1787, was a masterstroke in balancing the interests of both large and small states, forming a two-chamber system that has stood the test of time.
