Ali-Shir Nava'i in the context of "Bodleian Library"

Chagatai (چغتای, Čaġatāy), also known as Turki, Eastern Turkic, or Chagatai Turkic (Čaġatāy türkīsi), is a Turkic language that was once widely spoken across Central Asia. It remained the shared literary language in the region until the early 20th century. It was used across a wide geographic area including western or Russian Turkestan (i.e. parts of modern-day Uzbekistan, Turkmenistan, Kazakhstan, Kyrgyzstan), Eastern Turkestan (where a dialect, known as Kaşğar tılı, developed), Crimea, the Volga region (such as Tatarstan and Bashkortostan), etc. Chagatai is the direct ancestor of the Uzbek and Uyghur languages. Kazakh and Turkmen, which are not within the Karluk branch but are in the Kipchak and Oghuz branches of the Turkic languages respectively, were nonetheless heavily influenced by Chagatai for centuries.

Ali-Shir Nava'i was the greatest representative of Chagatai literature.

The Musalla complex (Pashto: د مصلی ترکيبي, Dari: مجتمع مصلی; lit. 'prayer complex'), also known as the Musallah complex or the Musalla of Gawhar Shah, is a former Islamic religious complex located in Herat, Afghanistan, containing examples of Timurid architecture. Much of the 15th-century complex is in ruins today, and the buildings that still stand are in need of restoration. The complex ruins consist of the five Musallah Minarets of Herat, the Mir Ali Sher Navai mausoleum, the Gawhar Shad Mausoleum, the ruins of the Gawhar Shad mosque, the Gawhar Shad madrasa complex, and the Sultan Husayn Bayqara madrasa and mausoleum complex.

Construction on the complex began in 1417 under Queen Gawharshad, the wife of Timurid ruler Shah Rukh, and ended in the late 1400s with the building of a madrassa by Sultan Husayn Bayqara. It was seriously damaged in 1885 during the Panjdeh incident, when the British and ruling Emir of Afghanistan demolished most of the complex buildings. Due to earthquakes and war, four additional minarets fell during the course of the 20th century.
