History
It was named after the Pechenegs, a Turkic semi-nomadic people which settled in this place in the 10th/11th century. When founded, the village bore the name Gerencik. It was colonized successively by Crimean Tatars (1857), Transylvanian shepherds (Mocani) (after 1878), ploughers from Brăila County (1885) and Râmnicu Sărat. From 1933 until 1940 the village was named Ion Gheorghe Duca, after the prime minister assassinated in 1933 by an Iron Guarddeath squad.
