Mahmud Gawan's execution by forged letter
Mahmud Gawan, a Persian merchant who became chief minister of the Bahmani kingdom, reformed its administration and extended its territory. In 1481 his Deccani rivals forged a letter that appeared to show him plotting treason, and a drunken Sultan Muhammad Shah III had him executed. Within a few decades the kingdom split into five successor sultanates, which makes the case a test of how quickly a state collapses once factions can remove its one integrating administrator.
