Muhakamat al-Lughatayn (Arabic: محاكمة اللغتين, literally Judgment between the Two Languages or The Comparison of the Two Languages), was one of Mir Ali-Shir Nava'i's masterpieces. Completed in December 1499, the Mukakamat defended Nava'i's view that the Chagatai Turkic language was superior to Persian for literary purposes. It was the writer's last definitive statement on the subject dearest to his heart, and the Muhakamat is a perfect example of an author's final work acting also as his last will and testament which was to emphasize the importance of his native language.
