"Abraham Lincoln" is responsible for ending slavery.
<u>Explanation:</u>
Lincoln started his political career by saying he was antislavery against the expansion of slavery but not advocating for immediate emancipation. Nevertheless, the man who started as antislavery finally released the Proclamation of Emancipation, which liberated all slaves in revolutionary nations.
Lincoln abolished slavery to destabilize the Southern resistance, reinforce the Federal government and promote free blacks to quarrel in the Union army, thereby maintaining the Union.
