Political boundaries kept moving in the later 5th and 6th centuries. Clovis I, king of the Franks (d. 511), conquered Alemannia, the Kingdom of Soissons and most of the Visigothic Kingdom north of the Pyrenees, and his sons conquered the Kingdom of the Burgundians in 534, thus creating a vast kingdom of Francia, which was however periodically divided between various members of the Merovingian dynasty. Meanwhile, Eastern Emperor Justinian I reestablished direct Imperial rule in Southern Spain, North Africa and especially Italy, reconquered during the hard-fought Gothic War (535–554). Later in the 6th century, Emperor Maurice sponsored Gundoald, a member of Clovis's Merovingian dynasty, in his claim to the Frankish kingdom, which however ended unsuccessfully in 585 at Saint-Bertrand-de-Comminges.
