Turmodigi

The Turmodigi were a pre-Roman ancient Celtic[1] people of northern Spain who occupied the area within the Arlanzón and Arlanza river valleys in the 2nd Iron Age.

The ancestors of the Turmodigi arrived at the Iberian Peninsula in the wake of the earlier Autrigones-Belgae migration at the 4th century BC, which settled in the area between the Arlanzón and Arlanza rivers.

However, the Turmodigi were not subdued until 56 BC, after a joint uprising with the Vaccei and other peoples was defeated by the Proconsul of Citerior Quintus Caecilius Metellus Nepos Iunior.

[10] Subjected to Cantabri and Astures raids, they allied themselves with Rome during the Astur-Cantabrian wars in the late 1st century BC, even allowing Emperor Augustus to establish its own[clarification needed] headquarters at their capital Segisama, thus turning Turmodigia into a rear base for the conquest of both Asturias and Cantabria.

In the midst of Augustus' administrative reform in 27 BC, the Turmodigi were incorporated into the Conventus Cluniensis, part of the new Hispania Tarraconensis province.
