What power did the governors have in the Roman provinces?

The vast Roman Empire was divided into provinces. The Romans paid great attention to roads that connected remote areas with the center. In each province, state power was exercised by governors. Which in fact were given great powers. The protégé of Rome was responsible for the domestic and foreign policy of the province entrusted to him. He was in charge of courts, civil and military affairs. The governor of the province was the second person, after the emperor, in the lands under his control.
