The Firman of 1830 refers to the Imperial Firman or Ferman (Decree) issued by Sultan Mahmud II in 1830. It declared the official liberation of Christian slaves of the Ottoman Empire. In practice it concerned the liberation of the Greek war captives who had been enslaved during the Greek War of Independence (1821–1829).

It was one of the reforms representing the process of official abolition of slavery in the Ottoman Empire, including the Firman of 1830, the Disestablishment of the Istanbul Slave Market (1847), the Suppression of the slave trade in the Persian Gulf (1847), the Prohbition of the Circassian and Georgian slave trade (1854–1855), the Prohibition of the Black Slave Trade (1857), and the Anglo-Ottoman Convention of 1880.^[1]
