Explanation:
Abraham Lincoln was the US president between 1860 and 1865, being the 16th American resident. At that time slavery was legalized in the southern United States, and there were speeches of dissemination to other states. Lincoln opposed slavery because it violated the principle of equality between men and liberal ideas, namely that all people were equal. In his government in 1965, the 13th constitutional amendment that emancipated all slaves in the country was approved.
