was abraham lincoln a democrat or a republican
He was a member of the Republican Party from 1854-1865. During most of his presidency until his assassination, he was a member of the National Union Party. Sorry, Abraham Lincoln was the first Republican President. The Republican party opposed Slavery, while the Democrat Party wanted to keep slavery. So war broke out between them, the Republicans vs the Democrats. This is why the Southern States were so solid Democrat for over 100 years after the Civil war.
