Timurid relations with Europe
Timurid relations with Europe developed in the early 15th century, as the Persianate Turco-Mongol ruler Timur and European monarchs attempted to operate a rapprochement against the expansionist Ottoman Empire. A strong hostility remained between the Timurds and the Ottoman Turks as well as the Egyptian Mamluks.
