North America 167 years ago today: Compromise of 1850 (09 Sep 1850).
With its population booming, California wanted to join the Union as a free state – naturally antagonizing the slave states. After lengthy debate, the Compromise of 1850 was agreed upon: California would be accepted as a free state and the newly created territories of Utah and New Mexico would be allowed to vote on the issue of slavery. Texas also agreed to abandon its substantial claims in the Mexican Cession in return for the payment of its debts.
