What two geographical regions were regained during Justinian?

During the reign of Emperor Justinian I, the Byzantine Empire successfully regained significant territories in two key geographical regions: North Africa and Italy. In North Africa, Justinian's general Belisarius reconquered the Vandal Kingdom, while in Italy, he fought against the Ostrogoths to reclaim much of the Italian peninsula. These military campaigns were part of Justinian's broader ambition to restore the Roman Empire's former glory.
