The three most influential figures before the Civil War were probably Henry Clay, John C Calhoon, Daniel Webster. Those people died nearly 10 years before the civil war began, but I do not know how much it will affect that. The rights of each country are very controversial issues, and the two sides have strong opposition and fundamental proposals. John C. Calhoun is in favor of giving the state authority to abolish the law deeming illegal and he advocates this theory as his "invalid theory."
Republican Republican Senator Henry Clay in Kentucky State is the first author of the compromise. He received strong support from Senator Daniel Webster of Massachusetts State and John C. Calhoun of South Carolina State. The Senate has established 13 Special Committees to prepare legislation proposals based on Clay's proposal. Committees include Senator John Bell of Tennessee, John M. Berrien of Georgia, Henry Clay of Kentucky, Solomon W. Downs of Louisiana, William R. King of Alabama. Williame P. Mangum in North Carolina, James M. Mason in Virginia, Jesse D. Bright in Indiana, Lewis Cass in Michigan, James Cooper in Pennsylvania, Daniel S. Dickinson in New York State Samuel in Vermont, Massachusetts S. Phelps and Daniel Webster
In a subsequent Senate debate on a compromise plan, the then three parliamentary giants - Henry Clay of Kentucky State, Daniel Webster of Massachusetts, and John Calhoun of South Carolina - announced the end of their lives. A wonderful speech (born 1782, died in 1850, Clay died in two years). Webster alleged compromise to save the alliance, and therefore alienated the Massachusetts abolitionists who formed the foundation of his support. Calhoun opposed compromise, arguing that the south enjoyed equal rights in the occupied territory. The North's opposition to compromise comes from young anti-slavery lawmakers like New York Senator William H. Seward who believes there is a higher law than the Constitution. The opponent succeeded in occupying until the sudden death of President Taylor in 1850, and he also opposed the plan of Clay. I successfully completed Vice President Millard Fillmore's compromise and achieved his success
