Shams al-Mulk Nasr

He was the son of Böritigin, a Karakhanid ruler from the western branch of the family, known as the "Alids", which was named after their ancestor Ali ibn Musa Qara Khan.

Shams al-mulk built the palace and gardens of Shamsabad in Bukhara, where the Karakhanids later lived.

[2] One of the most important Karakhanid structures, most of which survived at the beginning of the 20th century, is Rabati Malik.

It is located in Navoi, 110 km northeast of Bukhara on the road to Samarkand.

[3] During the reign of Shams al- mulk, Omar Khayyam was invited to Samarkand.
