The accidental discovery of her intact tomb during the Hungarian Revolution of 1848 has provided an opportunity for patriotic demonstrations. She was the only 12th-century Hungarian queen whose remains were studied by scientists, and her appearance was reconstructed.
The exact date of her birth is uncertain. It is assumed that she was born soon after the secret marriage of her parents, which took place before May 1153. The most common belief in historiography was that Agnes was born in 1154. At the baptism she probably received the name of Agnes.
In Constantinople. Marriage
Her father was captured by the Muslims in November 1160 and was confined in Aleppo for the next fifteen years. Princess Constance died ca. 1163/67, and around 1170 Agnes went to Constantinople, where her older half-sister Maria had been living as the wife of the Byzantine EmperorManuel I Comnenus. On the Emperor's request, Agnes was married to CaesarAlexios (born prince Béla of Hungary), who had been engaged to the Emperor's daughter, Maria Comnena until the birth of Manuel's son, Alexios in 1166. The wedding date of Agnes and Alexios is unknown; is believed that may have occurred about 1168 and no later than 1172. In historiography, there are two precises dated for the wedding: September 1169 and March 1171.
She received the name Anna in the imperial court. In the Hungarians documents she always appeared with her new name, probably because Agnes was rare at that time.
The spread of French cultural patterns in the Kingdom of Hungary is attributed to Anna/Agnes.
The Queen's activities were also connected with the presence in Hungary of the first Cistercian monks, who came from Burgundy. Anna could keep in touch with Burgundian Cistercians through ancestral linkages. The first Cistercian monastery in Hungary, founded in 1182, was in fact closely associated with three Cistercian abbeys located near Pontigny and the surrounding estates belonged to the Donzy family, from which Anna descended.
During her marriage, Anna gave birth to at least six children:

^Chronicler Alberic of Trois-Fontaines named Agnes one of the three daughters born from Constance and Raynald who was also the wife of the King of Hungary Béla (Chronica Albrici Monachi Trium Fontium [in:] Monumenta Germaniae Historica, XXIII, Hannover 1874, pp. 849–850). By contrast, in a fragmentary manuscript preserved from Lignages d'Outre-Mer and stored in the Vatican Library (Vaticanus Latinus 7806, Il parentado de Beimonte principe 9, fol. 172), are mentioned only two daughters from Constance and Raynald, who are named Joanna and Maria.
