Konstantinos Vagianis
Konstantinos Vagianis (18461919) was a Prince of Samos between March 7 1899 and 1900. He succeeded Stephanos Mousouros and was in turn succeeded by Michail Grigoriadis on August 16, 1900. He came from Neapolis in Cappadocia. He studied law in Constantinople and Athens. He became a professor of merchant law in Constantinople and appointed counselor to the Ecumenical Patriarchate of Constantinople. His reign as Prince of Samos was largely a failure because he adhered to only one political party. While at first he was beloved the Greek population of the island and loved them in turn, but he  later on forbade the Samian National Anthem and the Samian National Flag. He even dismissed a mayor because he protested strongly about that. Despite the privileges and rights of the people of the Principality of Samos, he tried to persuade the Ottoman Sultan to abolish the decisions of the former Parliament. For this reason, the Parliament asked for his replacement, to which the Sultan consented.
