Step-by-step explanation:
Roger Sherman, a representative from Connecticut and a significant Founding Father, played a crucial role in the drafting of the U.S. Constitution. One of his most notable contributions was the Great Compromise, also known as the Connecticut Compromise. This proposal, which he co-authored with Oliver Ellsworth, effectively resolved the deadlock between the larger states and the smaller states at the Constitutional Convention by establishing a bicameral legislature. The compromise led to the creation of two legislative bodies: the House of Representatives, with representation based on a state's population, and the Senate, with equal representation of two senators per state, regardless of size.
In addition to the Great Compromise, Roger Sherman also proposed the Three-Fifths Compromise alongside James Wilson, which played a pivotal role in the representation of enslaved individuals within the House of Representatives. Sherman, renowned for his political acumen, was one of the elite group of leaders who directly influenced the foundation of the American government by signing all four major state documents, including the Constitution. His work at the Constitutional Convention represents a foundational influence in the shaping of American legislation and federal structure that endures to this day.
