In June 1866, the Republicans proposed the 14th
amendment, which gave citizenship rights to all blacks in America.
Further, it banned the confederate leaders from holding any state
office until the Congress gave them permission to do so.
The southern state governments formed under the Johnson plan refused to ratify the 14th amendment. The Congress retaliated by passing a series of Reconstruction Acts (1867). These acts the temporarily placed the southern state governments under military occupation. The Congress also decided to enfranchise the blacks so that the southern white leaders would treat them fairly, if they wanted their votes. Besides, the Congress consented to the governments only if they accepted the 14th amendment.
