A rump state is the remnant of a once much larger state, left with a reduced territory in the wake of secession, annexation, occupation, decolonization, or a successful coup d'état or revolution on part of its former territory.[1] In the last case, a government stops short of going into exile because it controls part of its former territory.
Only after five more years did Esma'il and the Qezelbash finally defeat the rump Aq Qoyunlu regimes. In Diyarbakr, the Mowsillu overthrew Zeynal b. Ahmad and then later gave their allegiance to the Safavids when the Safavids invaded in 913/1507. The following year the Safavids conquered Iraq and drove out Soltan-Morad, who fled to Anatolia and was never again able to assert his claim to Aq Qoyunlu rule. It was therefore only in 1508 that the last regions of Aq Qoyunlu power finally fell to Esma'il.
