December 1250 CE
John III of Nicaea also promotes the isolation of Latin Constantinople by making pacts with Western leaders.
Since 1240, he has negotiated with German emperor Frederick II, and in about 1250 promises to become Frederick's vassal in return for aid in reconquering Constantinople.
Though the pact is sealed by John's marriage to the Emperor's daughter, Constance, little comes of their agreement: Frederick dies unexpectedly at fifty-six on December 13, 1250.
John has also negotiated, unsuccessfully, with the papacy, promising to end the schism between the Eastern and Western churches if the Latins return Constantinople.
