Answer:
President Johnson's blunders and the actions of the white South contributed to the adoption of more radical Congressional Reconstruction policies.
Step-by-step explanation:
Johnson, who became President after Lincoln's assassination, was a conservative who opposed many of the Reconstruction plans that were being put forward. He vetoed a number of important Reconstruction bills, including the Civil Rights Act of 1866, which granted citizenship and equal protection under the law to African Americans.
At the same time, the white South was actively resisting Reconstruction and attempting to maintain its power and control over the former Confederate states. This resistance took many forms, including the formation of paramilitary groups, such as the Ku Klux Klan, which used violence and intimidation to suppress African American rights and prevent them from participating in the political process. The white South also implemented a number of discriminatory laws, known as Black Codes, which imposed strict controls on African Americans and limited their rights and freedoms.
These actions by Johnson and the white South created a sense of urgency and frustration among Congressional Republicans, who believed that more radical measures were necessary to protect the rights of African Americans and to ensure a fair and just Reconstruction. As a result, Congress passed a number of Reconstruction Acts, which imposed military rule on the South and provided for the creation of new state governments that were more inclusive and representative of the African American population. These measures were opposed by Johnson, but they were ultimately successful in establishing a more just and equitable society in the former Confederate states.
