What was the main focus of most of the articles of impeachment against Andrew Johnson?

the primary charge against Johnson was that he had violated the Tenure of Office Act, passed by Congress in March 1867, over his veto.

Explanation:

the key accusation was that by trying to remove War Secretary Edwin M. Stanton without Senatorial approval, President Johnson had violated the Term of Office Act of 1867. Johnson opposed the allegation on the basis that the act was illegal and that it did not refer in any event to Stanton, who was confirmed before Johnson became president.
