Qaisar-e Sathrati (also written as Qaisar Sathratiye or (when feminine) Qaisar Banooye Sathratiye) is a Babkhan royal title, from 1538 to 1598 subsidiary to the Babkhan shah's titles, and thereafter recognized to belong to the Kaiser of Shireroth.
The title literally means "Kaiser of Shireroth", so in the years 1538–1598 there were two claimants to the Mango Throne, the Babkhan shah and the Shirerithian native kaiser (who at times, too, was Babkhan). For the most part this was a mere cosmetic claim, while at other times the claim was pursued vigorously by certain shahs.
From the rule of Kaiseress Noor and on, the Babkhan title is used in the preambles to identify the Kaiser/ess in exclusion to the Shirerithian native title as a homage to her dynasty's Babkhan roots. Although since her reign, the title Emir of Sathrati has been held concurrently with Qaisar-e Sathrati, the two titles are distict and ought not to be mixed up.
