Cultivated watermelon as we know it today appeared in the Ancient Egypt in the second millennium BC. Even the Bible mentioned watermelons as a food of Israelites while they were in Egypt. From there, watermelon started spreading. In 7th century AD it reached India and from there it reached China in the 10th century (today, China is the largest producer of watermelons).
