Sidicini

The Sidicini (Ancient Greek Σιδικῖνοι) were one of the Italic peoples of ancient Italy. Their territory extended northward from their capital, Teanum Sidicinum (modern day Teano), along the valley of the Liri river up to Fregellae, covering around 3,000 square kilometres (1,200 square miles) in total. They were neighbors of the Samnites and Campanians, and allies of the Ausones and Aurunci. Their language was Oscan.
