The historical reason Americans chose a bicameral system stems from the debate during the Constitutional Convention of 1787. The framers of the U.S. Constitution sought to balance the interests of states with large populations and those with smaller populations. This led to the Great Compromise, which created two legislative chambers: the House of Representatives (with representation based on population) and the Senate (with equal representation for each state). The bicameral structure was also influenced by the British Parliament's two houses and aimed to represent different stakeholders—common people in the House and states' interests in the Senate. Additionally, the Senate was designed to be more deliberative, with longer terms and initially appointed by state legislatures, ensuring stability and protection against rapid democratic changes. This system was intended to create a stable republic by balancing the power between different groups and preventing tyranny by any single one.
