That is a region situated in northeast Sumatra, now is the North Aceh district and the town of Lhokseumawe in Aceh, where was the royal capital of Sumatra in ancient times. The natives there, more often call it the kingdom of Samudra Pasai.
A reason which led to Sumatra later became the name of the island is due to the kingdom of Sumatra is a great maritime empire in the Strait of Malacca. As is known, that the Malacca Strait is the most important shipping lanes and trade in the world from ancient times until today. In the past, the path was called maritime Silk Road, which connects countries in the west and in the east of the world.
Sumatra (kingdom) is a largest trading town at this point where the traders from the east (China) and west (Arabic, Persian, Indian) come together and run their business. Therefore, the various commodities produced in the archipelago, will be brought to Sumatra, and marketed.
From here that Sumatra gained his popularity, and everyone from around the world who want to visit one of the places in this great island, they said, would go to Sumatra. Thus, in nautical terms in ancient times, a large island that situated in western part of Southeast Asia's most is identified with Sumatra (kingdom).
