Smyrna had been captured by
a crusade in 1344 and became a Papal city. The Turks continued to control the inland acropolis, however, but the sea-castle allowed the crusaders to control the harbour. From 1374, the Knights of Rhodes were in charge of its defences. In 1400, Timur launched a war against the Ottoman Empire that culminated in his victory at the
Battle of Ankara on 20 July 1402. In the aftermath of Ankara, the outpost of the
Genoese Maona at
New Phocaea sent a certain Galeazzo as an ambassador to Timur's camp to seek terms. He remained there three days, returning to New Phocaea with an agreement on 22 September. A knight, Brother Dominic de Alamania, was then sent to the island of
Chios, also belonging to the Genoese
Maona, in order to persuade the local leaders not to ally with Timur. While Timur's forces ravaged the Anatolian countryside, targeting Turkish settlements, the Knights of Rhodes prepared the defence of Smyrna. In 1398, under the direction of Brother Guillaume de Munte, a deep ditch had been dug across the promontory to separate the castle from the mainland. In 1402, the garrison of Smyrna numbered 200 knights under the command of the
Aragonese castellan
Íñigo de Alfaro. The garrison's pay was raised to 100
florins per knight per year. To cover the increased costs of defence of Smyrna, the central convent authorised an extraordinary subvention of 20,000 florins from the priories. Defensive preparations in the summer of 1402 were overseen by Admiral Buffilo Panizzatti, with a view to strengthening the system of defence before the expected Turco-Mongol assault. Munitions, supplies, money and reinforcements were continually arriving in the port. The attitude of the garrison was confident. According to Timurid historians, the fortress was thought to be impregnable. The
Greek Christian inhabitants of the countryside fled to the city for refuge. In order to avoid the costs of a siege, Timur sent two envoys, the
mirza Pir Muhammad and Sheikh Nur ed-Din, to the Knights commanding them to either convert to Islam or render him tribute (
jizya). The command was refused, although Buonaccurso Grimani, an ambassador from
Crete to Grand Master
Philibert de Naillac on Rhodes, records that the grand master sent an embassy to Timur. According to the contemporary papal notary
Dietrich of Nieheim, Smyrna would have been spared had Íñigo raised Timur's banner on the walls as he had been advised by a certain "Christian bishop", whom Dietrich does not name but who may have been
Francis,
bishop of Nakhchivan. ==Siege==
