Diederik

Diederik is a Dutch form of the Germanic name Theodoric, composed of the elements theud, meaning people or nation, and ric, meaning power or ruler, giving the overall sense of ruler of the people. The name was widely borne by medieval Germanic kings and nobles, most famously Theodoric the Great, the Ostrogothic king who ruled Italy in the late fifth and early sixth centuries. Diederik remains the characteristic Dutch rendering of this ancient name, with related forms including Dirk, Thierry, Derek, and Dietrich across various European languages and traditions.
