2. 1007–1012Iraq · IraqBaha al-Dawla spent vast sums to quell rebellions and family disputes, emptying the treasury; the Ziyarids permanently broke away from Buyid control in Tabaristan, and the Kakuyids grew powerful in Isfahan; by his death, the only major Iraqi cities under direct Buyid rule were Baghdad and Wasit.
