Step-by-step explanation:
As support began to weaken for reconstruction in the south, the Republican Party split and formed the new liberal republican party. The liberal republicans believed in letting the southern states decide their own future and granting full amnesty to former Confederates. They hoped that ending violence and strengthening the Republican Party would be achieved through their policy. This split caused a division within the party and weakened their overall support.
