This study provides a critical edition of chapters nine and ten of Muhit al-tavarikh (The Sea of Chronicles) by Muhammad Amin b. Mirza Muhammad Zaman Bukhari (Sufiyani). Muhit al-tavarikh is a valuable source for the study of late seventeenth-century Central Asian history, historiography, and language. The present work represents the first critical edition of a primary source of Subhan Quli Khan's reign. The ninth chapter (bab) offers accounts of the Timurid kings, Abulkhayrid/Shaybanid and the first four Ashtarkhanid/Janid khans. The tenth chapter presents a detailed account of the life and times of "the last great" Ashtarkhanid/Janid khan, Subhan Quli Bahadur (1682-1702), revealing historical information essential for scholars of the period and region.
