Anna Diogenissa

Anna of Byzantium (Serbian: Ана; ca. first half of the 12th century), also designated by some modern genealogists as Anna Diogenissa (Greek: Ἄννα Διογένισσα), was Grand Princess consort of Serbia, as wife of Uroš I, Grand Prince of Serbia (r. ca. 1112–1145). Her name is known only from late medieval Serbian genealogies, while her Byzantine origin was recorded by Italian chronicler Pietro Ranzano (d. 1492). Since Uroš I had several children, including sons Uroš II, Beloš and Desa, and also daughters Helena of Serbia, Queen of Hungary and Marija, Duchess of Znojmo, Anna is considered as their mother.
