Khorasan Wars were a series of battles that took place in the early 1580s in the cities of Mashhad, Nishapur, Torbat Heydarieh and other regions of Khorasan. These wars broke out due to the challenges between the "Shamlu" and "Stajalu" clans (supporting Abbas the Great) and the "Teklo" and "Turkmen" (supporting king Mohammad Khodabandeh) clans. Khorasan conflicts were a beginning to the coming to power of Abbas the Great and his kingdom.
