Their name supposedly meant "kings of the world". Early in the 1st century BCE, they had been one of the main Gaul tribes, especially in terms of druids and their political influence. But they soon declined in power as the druids were an important target for Julius Caesar in his conquest of Gaul. What is more, the fact that Avaricum (Bourges) was the only Celtic city that Vercingetorix did not burn, contrary to his scorched earth strategy, upon the approach of Caesar's legions is another proof of the political importance of the Bituriges. Eventually, the town was to be buried by the Roman legions.
They joined Bellovesus'migrations towards Italy, together with the Aeduii, Ambarri, Arverni, Aulerci, Carnutes and Senones.
