2 mar 1820 año - Missouri Compromise
Descripción:
Missouri, a slave state, was admitted into the union as long as Maine joined as a free state. This introduced the "above the line rule". Any state "above the line" would have to be a free state, while any state below the line could choose to be a slave state.
