What action did president Andrew Johnson tale during the reconstruction?

During Reconstruction, President Andrew Johnson implemented a lenient approach towards the Southern states, allowing them to rejoin the Union with relatively minimal requirements. He issued a series of pardons to former Confederate leaders and allowed Southern governments to establish themselves without significant federal intervention. Johnson's policies, which aimed to quickly restore the Union, faced criticism for failing to protect the rights of newly freed African Americans and for enabling the rise of discriminatory laws in the South. His approach ultimately led to a conflict with Congress and contributed to his impeachment in 1868.
