Gyula (
Yula, Gula, Gila) was, according to
Muslim and
Byzantine sources, the
title of one of the leaders, the second in rank, of the
Hungarian tribal federation in the 9th–10th centuries. In the earliest Hungarian sources, the title name is only recorded as a
personal name (
Gyyla,
Geula,
Gyla,
Iula). The title name do not have convincing
etymologies, but it is probably of
Turkic origin.
