Among the many Ottoman provinces (eyalets or vilayets) that were created during the centuries-long history of the Ottoman Empire, some existed for relatively short amounts of time, either because they were ceded to foreign powers, obtained independence, or were simply merged with other provinces.
The Eyalet of Tiflis was taken from Kartli in 1578/9, but the country proved difficult to subdue: Tiflis was lost in 1583, the Ottomans then lost the whole land except for Lori and Gori, and both were made eyalets in place of Tiflis, but were later lost in 1590 and 1599 respectively.

The Eyalet of Kurdistan (Ottoman language: ايالت كردستان, Eyâlet-i Kurdistân) existed from 1847 to 1867 (20 years). Confusingly, some neighbouring eyalets, such as Sharazor, were also sometimes referred to as "Kurdistan". It was established by the Ottoman Empire following the suppression of Bedirhan Bey's revolt in 1847. On December 14, 1847, the Ottoman State newspaper - Takvim-i Vekayi Gazetesi - carried an official notice announcing the establishment of 'the Province of Kurdistan'. The area of the eyalet was populated mainly by Kurdish speaking Muslims. As to its yearbook, it included Hakkâri, Dêrsîm, Diyâr-ı Bekr in 1849. The territorial setup was later altered and it was disbanded in 1867.
