This is not surprising, because the governor himself remained in the annals as a great scientist, mathematician and astronomer. Science played a crucial role in his life and in the years of his reign in Mawarannahr he raised it to unbelievable heights.

Mirzo Ulugbek was born in Sultania on March 22, 1394. At age 15, in 1409, he was appointed as governor of Samarkand, and from 1447 headed the Timurid dynasty after the death of his father, Shahrukh, the eldest son of Amir Timur.

Due to its pedigree, Ulugbek had the opportunity to visit the best of the libraries, the observatory of the time since childhood. His love of the heavenly bodies has manifested in a rather early age.  In 1428 he completed the construction of the observatory, named in his honor. There was no analogue observatory in the world. The eminent astronomers could work here, who, like himself, Mirzo Ulugbek, made an enormous contribution to the development of this science.

The surviving underground part of Ulugbek’s observatory is one of the most popular tourist attractions among tourists. Everyone wants to see how people in those early years made discoveries which are valued until now. It is in this great observatory Ulugbek cataloged starry sky – Zij-i Sultani – which described 1018 stars. The length of the sidereal year was also determined here: 365 days, 6 hours, 10 minutes, 8 seconds (with an accuracy of +58 seconds).

All of his astronomical observations Ulugbek wrote in “Zij jadidi Guragani” (New Guragani astronomical tables), which are considered as his main scientific work. Until XVII century the accuracy of these tables exceeds all available data in this area.

Also in the years 1417-1420 by the order of Ulugbek madrassah was built in Samarkand, which was the first structure of the future architectural ensemble of Registan.

Ulugbek was killed in October 1449.
