The Siege of Nicaea of 727 was an unsuccessful attempt by the Umayyads, the Byzantine city of Nicaea, the capital of the topic of Opsikion to conquer. After forty days of siege, the Arabs broke off the attempt and returned to the caliphate. The successful defense helped the Emperor Leo III. in enforcing its iconoclastic policy.
