The Great Compromise focused on how congress should be set up. James Madison came up with the Virginia plan. The Virginia plan was the idea that the number of people in congress per state should be according to the population of that state. William Patterson came up with the New Jersey plan. The New Jersey plan was the idea that the number of people in congress per state should be equal. Henry Clay compromised by suggesting a bicameral congress. The senate would be based off equality (New Jersey plan) and the House of Representatives would be based off of population (Virginia plan). The bicameral congress is still used to this day in the United States. I hope this helps. :)
