How was Lincoln changing his opinion of blacks shortly before he was assassinated?

Shortly before his assassination, Abraham Lincoln's views on African Americans evolved significantly. He began to advocate for greater rights for freed slaves, including the possibility of voting rights for some educated and serving Black men. Lincoln's support for the Thirteenth Amendment, which abolished slavery, along with his willingness to consider the integration of Black individuals into American society, reflected a more progressive stance than he held earlier in his presidency. This shift highlighted his belief in a more inclusive vision for the nation as the Civil War drew to a close.
