Pulling some examples from an arbitrary list:

Johnson vetoes a bill calling for the extension of the Freedmen's Bureau. The bill, a response to the repressive Black Codes of the South, would expand the power of the Bureau, the organization formed for the freedmen's protection.

Johnson vetoes the Civil Rights Act, a second attempt by Congress to provide freedmen with federal citizenship after the failed Freedmen's Bureau bill. The act sanctions the employment of federal troops for enforcement. The Senate overrides Johnson's veto on April 6. Three days later, the House of Representatives also overrides the veto.

With the mandate of the 1866 election, Congress (despite Johnson's veto) passes the First Reconstruction Act, setting up five military districts in the South, each under the direction of a presidentially-appointed military commander. The legislative body also passed the Army Appropriations Act, which lessens Johnson's control of the Army. Finally, Congress passes -- again over Johnson's veto -- the Tenure of Office Act, prohibiting Johnson from removing cabinet officers without the Senate's consent. In this final piece of legislation, Congress hopes to protect Secretary of War Edwin Stanton, the sole Radical Republican in Johnson's cabinet.

Johnson vetoes the Second Reconstruction Act, which orders military commanders to call elections in the South. Congress overrides Johnson's veto that very day.

Johnson vetoes the Third Reconstruction Act, which spells out election procedures in the South and reasserts congressional control over Reconstruction. Congress again overrides Johnson's veto on the same day the President delivers it.

A couple years later:

President Johnson delivers his final annual message to Congress, again requesting the repeal of the Reconstruction Acts.

He also campaigned against the "Radical Republicans" who wanted to, you know, oppose the reinstitution of slavery in the South and the reinstating of Confederates in seats of power, and fought with the more progressive cabinet members he inherited from Lincoln.
