May I suggest that you do further research on Abe.
“If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that.”…Abraham Lincoln.
During a speech to Charleston, Illinois in 1858, Lincoln said:
I am not now, nor ever have been in favor of bringing about in any way the social or political equality of the white and black races. I am not now nor ever have been in favor of making voters or jurors of Negroes, nor of qualifying them to hold office, nor of intermarriages with white people. There is a physical difference between the white and the black races which will forever forbid the two races living together on social or political equality. There must be a position of superior and inferior, and I am in favor of assigning the superior position to the white man.
The Republican Party was born in the early 1850's by anti-slavery activists and individuals who believed that government should grant western lands to settlers free of charge. The first informal meeting of the party took place in Ripon, Wisconsin, a small town northwest of Milwaukee. The first official Republican meeting took place on July 6th, 1854 in Jackson, Michigan. The name "Republican" was chosen because it alluded to equality and reminded individuals of Thomas Jefferson's Democratic-Republican Party. At the Jackson convention, the new party adopted a platform and nominated candidates for office in Michigan.In 1856, the Republicans became a national party when John C. Fremont was nominated for President under the slogan: "Free soil, free labor, free speech, free men, Fremont." Even though they were considered a "third party" because the Democrats and Whigs represented the two-party system at the time, Fremont received 33% of the vote. Four years later, Abraham Lincoln became the first Republican to win the White House.
The Civil War erupted in 1861 and lasted four grueling years. During the war, against the advice of his cabinet, Lincoln signed the Emancipation Proclamation that freed the slaves. The Republicans of their day worked to pass the Thirteenth Amendment, which outlawed slavery, the Fourteenth, which guaranteed equal protection under the laws, and the Fifteenth, which helped secure voting rights for African-Americans.
