The internal administration of Grand Duke Gediminas of Lithuania bears all the marks of a wise ruler.

He protects the Catholic as well as the Orthodox clergy; he rhas aised the Lithuanian army to the highest state of efficiency at this time attainable; defended his borders with a chain of strong fortresses and built numerous castles in towns including Vilnius.

At first he had moved the capital to the newly built town of Trakai, but in about 1320 reestablished a permanent capital in Vilnius.

He dies in 1341 and is succeeded by one of his sons, Jaunutis, who will prove unable to control the unrest in the country.
