The Great Compromise <em>(Or the Connecticut Compromise of July 16, 1787) </em>was a compromise began by Roger Sherman and Oliver Ellsworth, in which <u>it was stablished a Congress representation bicameral system</u>, compound of the Senate and the House of Representatives, where in the Senate it'd be assigned an equal seats number by state, but in the House of Representatives, there would be assigned a seats number according to each state population proportion.
And the Great Compromise was compared to the Virginia and New Jersey Plans, <u>because that Compromise arised from a disccordance between the Virginia Plan</u> <em>(Or the James Maddison's plan) </em><u>and the New Jersey Plan </u><em>(Or the Paterson’s New Jersey Plan)</em> that were presented in the Convention of May 14 to September 17, 1787, in Philadelphia, Pennsylvania. Moreover, the Virginia Plan proposed important changes in the Congress structure, stablishing a Bicameral system, but by other side the New Jersey plan was based in the confederation articles, stablishing an Unicameral congress System, so to resolve those diferences, on June 11, 1787, Roger Sherman and Oliver Ellsworth <u>proposed the Connecticut Compromise, where were included proposals from both plans.</u>
