This film is the most expensive film in Turkish history, with a production cost of 17 million US dollars. The film is adapted from the historical battle of Mehmed II to capture the Byzantine capital Constantinople in 1453. The production began in 2009 and lasted for 3 years. In 1453, the Byzantine capital Constantinople was surrounded by Turkish invaders. As the empire's treasury gradually became empty, Constantinople was only a shadow of its former glory, while the Turkish Empire gradually became stronger. After enduring the Byzantine Empire for so many years, the ambitious Sultan Mehmed II (played by Devrim Evin) launched a campaign to end the Byzantine Empire. He led cavalry and warships to capture the Byzantine capital Constantinople, thus ending the Eastern Roman Empire's rule for more than a thousand years, conquered Constantinople in the name of the Turks, and established the Ottoman Empire as a country spanning Europe and Asia, where Eastern and Western civilizations met.
