The Emancipation Proclamation took effect on January 1, 1863. This landmark executive order was issued by President Abraham Lincoln during the Civil War and was intended to free slaves in the Confederate states. The proclamation had a significant impact on the war and the future of slavery in the United States, as it reframed the conflict as a fight not just for the Union but also for freedom. It also allowed for the enlistment of Black soldiers in the Union Army, further solidifying the fight against slavery as a central objective of the war.

The other years mentioned do not align with the historical timeline of the proclamation's issuance and effect, making them incorrect choices. For instance, 1850 was a year notable for the Compromise of 1850, which dealt with the territorial expansion of slavery, while 1861 was the year the Civil War began, and 1870 occurred after the ratification of the 15th Amendment, which addressed voting rights, rather than issues of emancipation. Thus, 1863 is the only correct answer involving the implementation of the Emancipation Proclamation.
