Carola, wife of Obelerio degli Antenori
Carola (fl. 809), was the Dogaressa of Venice by marriage to the Doge Obelerio degli Antenori (r. 804-809). She was politically active and exerted influence over the affairs of state. She was the first consort of a Venetian doge with the title and position of dogaressa of Venice.
Carola was originally a Frankish countess and a lady-in-waiting to the empress of Charles the Great. She met Obelerio when he and his brother Beato visited the court of Charles in Aix-La-Chapelle. Charles gave his blessing to the union and declared it to be a political alliance and gave his protection to Venice. Carola was described as strong-willed, energetic and with an ability to create respect and obedience. She was somewhat disliked for the perceived Frankish influence she represented.
