Childebert III, Frankish king (born 670)

Year 711 (DCCXI) was a common year starting on Thursday of the Julian calendar. The denomination 711 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Childebert III, called the Just, was the son of Theuderic III and Chrothildis and sole king of the Franks (694–711). He was seemingly but a puppet of the mayor of the palace, Pepin of Heristal, though his placita show him making judicial decisions of his own will, even against the Arnulfing clan. His nickname has no comprehensible justification except possibly as a result of these judgements, but the Liber Historiae Francorum calls him a "famous man" and "the glorious lord of good memory, Childebert, the just king."
