It is composed of three villages: Diniaș, Peciu Nou and Sânmartinu Sârbesc. The territory of the commune has been inhabited since ancient times. During the Dacian statehood and the Roman rulership, a Roman colony was established here under the name Vibech. During the Migration Period, Peciu Nou fell under Hungarian rule; the first recorded mention of Peciu Nou also comes from this time. Between 1401–1406, the locality was a royal domain with urban status. In 1526 Hungary became a pashalik; after this period the sultan colonized many Serbs in Banat, and the name of the locality was changed from Vibech to Peciui.
