Anna Diogenissa

Anna Diogenissa (ca. 1074–1145) was a Byzantine noblewoman of the Diogenes house who became the Grand Princess consort of Serbia as wife of Uroš I, Grand Prince of Serbia (r. 1112–1145). She had five children with Uroš I, including the successor, Uroš II (r. 1145–1162).

Life
Anna Diogenissa was born in the Byzantine capital Constantinople the year after the death of her father Constantine Diogenes at Antioch in 1074. Her mother was Theodora Komnene, a daughter of the powerful noblewoman Anna Dalassena and John Komnenos, and hence sister to the future emperor Alexios I Komnenos (r. 1081–1118). Her paternal grandparents were Romanos IV Diogenes (r. 1068–1071) and Anna of Bulgaria.

It is not recorded when Anna married Uroš I, the Serbian Grand Prince, who reigned from ca. 1112 to 1145. It most likely took place during Urošʻs captivity in Byzantium, where he had been sent as a hostage by his uncle Vukan following the capture of Lipljan in 1094 by the troops of Alexios I Komnenos. Uroš is credited with having unified most of the Serbian territories after retaking them from Byzantine occupation. Rascia was the first independent state of the Serbs which had been formed in the 8th century.

Together they had at least five children: Possible child of Anna and Uroš:
 * Uroš II, Grand Prince of Serbia
 * Desa
 * Beloš
 * Helena, Queen of Hungary and Croatia (d. after 1146), married King Béla II of Hungary
 * Marija, married Conrad II of Znojmo, mother of Helen of Znojmo
 * Zavida, Lord of Ribnica
