On this date in 1865 the Congress voted to end slavery. The vote was 119 "yea" and 56 "nay" with 8 Congressmen not voting. It should be noted that every Republican Congressman voted to end slavery (along with 14 Democrats). Of the 56 "nay" votes 50 and all of the not voting (the voting "present" of the day) came from the Democrats.
Just something to keep in mind when you hear the Republicans are the "racist" party.
