Bursa is the center of the Turkish automobile industry, where FIAT and Renault have located their factories. The earliest known site at this location was Cius, which Philip V of Macedonia granted to the Bithynian king Prusias I in 202 BC, for his help against Pergamum and Heraclea Pontica (modern Karadeniz Eregli). Prusias renamed the city for himself, Prusa. It was later a major city, located on the westernmost end of the famous Silk Road, and was the capital of the Ottoman Empire following its capture from the Byzantines in 1326 until the capture of Edirne in 1365 and remained an important administrative and commercial center even after it lost its status as the capital. The Algerian resistance fighter Emir Abd el-Kader resided here for a while and Ismail Hakki Bursevi a famous Islamic scholar and Sufi is buried here.
