Many prominent explorers have written accounts of their travels through Bakhtiari territory and their encounters with the Khans. Major Sir Henry Rawlinson published the account of his journey in 1839. Sir Henry Layard traveled to Bakhtiari on his way to Afghanistan in 1840 and befriended the great Khan of Char Lang, Mohammad Taghi khan. Layard remained in Bakhtiari for two years and wrote about it in his 2 volumes of "Early Adventures in Persia, Susiana & Babylonia".
