The treaty (or another treaty with similar provisions) was ratified anew once Emperor Manuel II returned from the West later in the year.[24] The treaty was very unpopular with the Ottomans due to its concessions, but the need to keep his rear secure while engaged in the civil war of the Ottoman Interregnum with his brothers forced Süleyman to adhere to it until his own overthrow in 1411.[25] Nevertheless, the opposition of the powerful Ottoman frontier warlords (uch bey), such as Evrenos Beg, may have resulted in at least one major omission from the treaty: Gallipoli itself remained in Ottoman hands, thereby averting the extremely disadvantageous position that had resulted from its temporary loss to the Savoyard crusade in 1366, when the Ottoman domains in Anatolia and Europe had been effectively sundered apart.[26]
