who had the largest role in writing the missouri compromise
Missouri Compromise When free-soil Maine offered its petition for statehood, the Senate quickly linked the Maine and Missouri bills, making Maine admission a condition for Missouri entering the Union with slavery unrestricted. Senator Jesse B. Thomas of Illinois added a compromise proviso, excluding slavery from all remaining lands of the Louisiana Purchase north of the 36Â° 30' parallel. The combined measures passed the Senate, only to be voted down in the House by those Northern representatives who held out for a free Missouri. Speaker of the House Henry Clay of Kentucky, in a desperate bid to break the deadlock, divided the Senate bills. Clay and his pro-compromise allies succeeded in pressuring half the anti-restrictionist House Southerners to submit to the passage of the Thomas proviso, while maneuvering a number of restrictionist House northerners to acquiesce in supporting Missouri as a slave state.[4][5] The Missouri question in the 15th Congress ended in stalemate on March 4, 1819, the House sustaining its northern antislavery position, and the Senate blocking a slavery restricted statehood.
Connecticut Compromise Roger Sherman and Oliver Ellsworth, both of the Connecticut delegation, created a compromise that, in a sense, blended the Virginia (large-state) and New Jersey (small-state) proposals regarding congressional apportionment. Ultimately, however, its main contribution was in determining the apportionment of the Senate. Sherman sided with the two-house national legislature of the Virginia Plan but proposed "That the proportion of suffrage in the 1st. Branch [house] should be according to the respective numbers of free inhabitants; and that in the second branch or Senate, each State should have one vote and no more."[6] Although Sherman was well liked and respected among the delegates, his plan failed at first. It was not until July 23 that representation was finally settled.[6]
