As late as 1221, Debal appears to have remained an important port city; according to the Jahan-kusha describes that Jalal al-Din Mangburni approached the city that year, and its ruler Hasrar fled, allowing him to enter the city unopposed.
The passage describes Debal's importance as a port city in 1221, supported by the Jahan-kusha account of Jalal al-Din Mangburni's successful entry into the city after Hasrar fled.
