Why did president johnson lose control of reconstruction?

Radical Republicans expanded their Congressional majority in the elections of 1866.

Explanation:

President Johnson had a different view of the Reconstruction, he defended that the southern states did not give up their right to govern themselves and the federal government had no right to determine a series of questions that were state-level questions.

Because of that Johnson gave the southern states the free reign to rebuild themselves. This caused the creation of the black codes, that were a series of laws that removed the basic rights of African Americans.

This ideas of President Johnson caused him to lose northern votes in the congressional elections of 1866. Congress then passed the Reconstruction Act of 1867 that divided the South into 5 military districts and outlines how governments should be organized.

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
