I half of XVI century One year before his father Suyienish-khodja khan’s death a year of 1534, defeating Janibek khan’s grandson-Tair khan, Keldi Mohamad sultan takes over Turkestan. Later, Keldi Mohamad sultan and his children were buried in Turkestan. This was written by historian Zayn ad-din Mahmud Wasifi (1485–1566.) in his commemorative book “Extraordinary events”. The book says that after Mohamed’s death his was buried nearby mausoleum of Khodja Ahmed Yasawi (in mausoleum of Rabiya Sultan Begim), and ordered Wasifi to compose poems “Marsiya”. A whole month did “stonecutter” (person making rock carvings) waited for those poems. Mausoleum of Rabiya Sultan Begim was built after death of Shaybani khan in 1510, after coming to power Koshkenshi khan before 1530s. Presumably, Keldi Mohamad died after the son of Mubarak shah sultan (died in 1519), son of Kul Mohamad sultan ( died in 1524), daughter of Mastura khanum (died in 1519), father of Suyinish-khodja khan (died in 1525), Koshkenshi khan’s great uncle (died in 1530).
