In this lecture Thomas Sinclair will look at the most prosperous period of east-west trade through Armenia—the period of the Il-Khans—in the second half of the Middle Ages (1100-1500), and within that period at the most important avenue of trade. It ran from Ayas in the Armenian kingdom of Cilicia to the city of Sivas/Sebasteia, then through Armenia to the Il-Khanid capital of Tabriz.
