Some studies indicate that the Black Death, which devastated Europe starting in the late 1340s, may have reached Europe from Central Asia (or China) along the trade routes of the Mongol Empire. One theory holds that Genoese traders coming from the entrepot of Trebizond in northern Turkey carried the disease to Western Europe; like many other outbreaks of plague, there is strong evidence that it originated in marmots in Central Asia and was carried westwards to the Black Sea by Silk Road traders.
