(1600), including eastern regions, known today as the
Old Herzegovina The region known today as the
Old Herzegovina was part of
historical Herzegovina from the middle of 15th century up to the 1878. Initially it was part of the medieval
Duchy of St. Sava (), established by
duke (, )
Stefan Vukčić Kosača within the
Kingdom of Bosnia. After the Ottoman conquest, it was part of the
Sanjak of Herzegovina. Between 1580 and 1833, Sanjak of Herzegovina was part of the
Bosnia Eyalet, and then became a separate
Herzegovina Eyalet (1833–1851), of the
Ottoman Empire. The major (western and central) part of historical Herzegovina was occupied by
Austria-Hungary in 1878, after the
Congress of Berlin, and that region became part of the
Condominium of Bosnia and Herzegovina. Since then, the name of
Herzegovina was reduced to that region. In the same time, eastern portion of historical Herzegovina was annexed to the
Principality of Montenegro (1878), while some sections remained under Ottoman rule (
Sanjak of Pljevlja) until 1912, when they were divided between Montenegro and Serbia. All of those regions of historical Herzegovina, detached from it since 1878, became known as the
Old Herzegovina. ==See also==
