Another version is that "riau" is derived from the Malay word "riuh," which means crowded, frenzied working people"." This word is believed used to reflect the nature of the Malay people in present-day Bintan. The name is likely to have become famous since Raja Kecil moved the Malay kingdom center from Johor to Ulu Riau in 1719. This name was used as one of the four main sultanates that formed the kingdoms of Riau, Lingga, Johor and Pahang. However, as the consequences of the Anglo-Dutch Treaty of 1824 between the Netherlands and United Kingdom, the Johor-Pahang sultanates fell under British influence, while the Riau-Lingga sultanates fell under Dutch influence.
