Early accounts tell us that Singapore may have been founded by Sang Utama and grew into a thriving trading center under his descendants, according to the Malay Annals. Wang Dayuan's account from 1330-1340 also describes Singapore as a bustling port. Archaeological evidence, including Chinese porcelain and coins dating back to the 14th-15th centuries, supports that Singapore was an important trading hub, though some dispute remains about how much is legend. After the 15th century, Singapore lost importance as a trading port after its ruler was driven out by the king of Siam.
