IMBROS, an island in the Aegean belonging to Turkey, at the southern end of the Thracian Chersonese peninsula. Herodotus (v. 26) mentions it as an abode of the historic Pelasgians (q.v.). It was, like Samothrace, a seat of the worship of the Cabeiri (q.v.). There is much volcanic rock and parts of the island are very fertile. Wheat, oats, barley, olives and fruit are grown. The island was occupied by Greece during and after the World War. It was also an important base for the British and Allied operations in the Eastern Mediterranean at the same time. It was returned to Turkey by the Treaty of Lausanne (1923). Its population is about 9,000.
