Spices have been traded for thousands of years along routes connecting South Asia, the Middle East, and East Asia. Arab and Indian merchants facilitated land routes through the Middle East and India, while Indonesian merchants traveled throughout Asia and East Africa. The Portuguese took control of sea routes in the 15th century, reducing Europe's reliance on Venetian merchants for spices. The discovery of the Americas in the late 15th century introduced new spices like vanilla, chili peppers, and chocolate to Europe. Today, India and Indonesia are the largest exporters of spices, with pepper being the most widely traded.
