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.
Kansas–Nebraska Act The Kansasâ€“Nebraska Act divided the nation and pointed it toward civil war.[65] The Act itself virtually nullified the Missouri Compromise of 1820. The turmoil over the act split both the Democratic and Whig parties and gave rise to the Republican Party, which split the United States into two major political camps, the Republican North and the Democratic South.
