モレアス専制公領
On 4 June 1395, together with Saint Superan, he was defeated and captured by the Byzantine Greeks of the Despotate of the Morea, but was released in December, after the Venetians paid a ransom of 50,000 "hyperpyra" for him and Saint Superan. In 1396, he received a letter from Pope Boniface IX, which extended papal protection over him and urged him to fight against the growing menace of the Ottoman Turks.
