Baysunghur

Ghiyath ud-din Baysunghur (persian: غیاث‌الدین بایسنقر) commonly known as Baysonqor or Baysongor, Baysonghor or (incorrectly[2]) as Baysunqar, also called Sultan Bāysonḡor Bahādor Khan (1397–1433) was a prince of the Timurid dynasty.

[2] In the view of modern historians, Baysunghur was actually a better statesman than his more famous elder brother, Ulugh Beg, who inherited Shah Rukh's throne,[2] but who "must have envied his younger brother, Baisunghur, whom his father never saddled with major responsibilities, which left him free to build his elegant madrasas in Herat, gather his ancient books, assemble his artists, and drink".

He was a patron of Persian historians, including Hafiz-i Abru (died 1430), who dedicated his book Zubdat al-tawārīkh-i bāysunghurī to him.

After taking Tabriz, in 1421 he brought back to Herat a group of Tabrizi artists and calligraphers, formerly working for Ahmad Jalayir, who he installed in Herat to add to his existing artists from Shiraz.

They became the most important school of artists in Iran, merging the two styles.
