trade, as merchants brought the disease to the Mediterranean Sea

Explanation:

The black death is the name for the pandemic of the bubonic plague that started in 1346. and resulted in the death of a third of Europe’s population. The disease reportedly began in the plains of Central Asia.

The trade of Asia and Europe was well established at the time, mostly via the Silk Road. Sadly, with the goods from the trade, came the infectious diseases – plague among them. Studies show that the original wave started from Crimea and the port on the Black Sea. Italian merchants went from the port back to their homes, and the disease spread fast all over Europe soon. Some also say another wave started from Constantinople around the same time, as it was one of the trade centers as well. The disease was spreading firstly over the Mediterranean and later went into the whole of continental Europe.
