I want to know the answer to the following question:
Whose death in 1779 led to a civil war in Iran?
All the background I'm provided with is that "In 1795, following the disobedience of the Georgian subjects and their alliance with the Russians, the Qajars captured Tblisi by the Battle of Krtsanisi, and drove the Russians out of the entire Caucasus, reestablishing a short-lived Iranian suzerainty over the region.". Is that enough to answer the question?
