Protosebastos

The title of protosebastos (, prōtosébastos, "first sebastos") was a high Byzantine court title created by Emperor Alexios I Komnenos.

==History== Although the title first appears in a document of 1049, where Domenico I Contarini, the Doge of Venice, uses it alongside the title of patrikios to refer to himself, it is commonly accepted that it was created by Emperor Alexios I Komnenos (). It was first conferred to his brother Adrianos, while another early holder, his brother-in-law Michael Taronites, was soon after raised to the even higher title of panhypersebastos. It was also conferred on Sergius VI of Naples and his son, John VI, at about the same time.
