History: According to mythology, the city of Cius was
founded during the expedition of the Argonauts. It was
totally destroyed by Philippe V of Macedonia in 202 BC.
The land was then offered to Prusias I who gave the town
its name and added "ad Mare" to distinguish it from 
Prusias ad Hypium. Henceforth it belonged to the kingdom
of Bithynia. In 72 BC during the third war against 
Mithridate VI of Pontus, the city opened its gates to the
Roman generals and was declared a free town (civita libera). 
The city resumed its original name under Claudius.
