Answer:

reconquering lost lands

Brief Explanations:

Justinian I aimed to restore the Roman Empire's former glory by reconquering lands that were once part of it. He launched military campaigns to reclaim territories in the Western Mediterranean that had been lost after the fall of the Western Roman Empire. Conquering new - lands was not his main priority compared to this restoration goal. Demanding tax payments was a means to an end for funding his ambitions, not a primary goal. He was a Christian and did not oppose Christianity.
