From 1803 to 1878, as a result of numerous Russian wars now against Ottoman Turkey, several of Georgia's previously lost territories – such as Adjara – were recovered, and also incorporated into the empire. The principality of Guria was abolished and incorporated into the Empire in 1829, while Svaneti was gradually annexed in 1858. Mingrelia, although a Russian protectorate since 1803, was not absorbed until 1867.
