== History == The names Mościska and Mostyska'' share a common etymological Slavic root "most", which means "bridge", or the place associated with "river crossings". In 1340, Mostyska, together with the territory of Red Ruthenia, was annexed by Polish King Kazimierz Wielki, and the town remained in Poland for over 400 years, until 1772 (see Partitions of Poland). Mościska, as it was called, was in the Przemyśl region, and the Ruthenian Voivodeship. In 1404, King Wladyslaw Jagiello granted it a Magdeburg town charter. Mościska was the seat of a starosta, and the town was severely damaged several times destroyed during Tatar, Turkish and Wallachian raids.
