MARRUCINI, a people of Central Italy, inhabited a narrow strip of land extending along the banks of the River Aternus (Pescara), from the Adriatic to the Apennines, and bounded on the S. by the territory of the Frentani. Their country, on account of its eastern exposure, was more fertile than the neighbouring districts. Teate (Chieti), situated on the Aternus, was their most important city. The Marrucini were of Sabine origin. They were an independent people, although they almost invariably appear in history as allies of the neighbouring tribes of the Marsi and Peligni. Along with these they became confederates of the Romans in 304 B.C., and revolted at the commencement of the Social War. Their district was included in the Fourth Region of Augustus.
