After 1511, the Riau islands became the center of political power of the Sultanate of Johor based on Bintan island and were then considered the center of Malay culture.
When European nations began combing the seas for new opportunity, as they did elsewhere, they changed the fate of Riau as a political, cultural or economic center as they struggled to control the prime regional trade routes through the Malacca Straits. Singapore island, which had been part of the same greater Malay kingdoms and sultanates, and under direct control of the Sultan of Johor, came under control of the British.
The creation of a European-controlled territory broke the sultanate into two parts, destroying the cultural and political unity that had existed for centuries. The Anglo-Dutch Treaty of 1824 consolidated this separation, with the British controlling all territories north of the Singapore strait and the Dutch controlling territories from Riau to Java.
After the European powers withdrew from the region, new independent governments reorganized after inheriting 100 years of colonial boundaries. The territories of Indonesia, Malaysia, Singapore, Brunei and Borneo struggled and came into military conflict against each other, and the Riau islands once again found themselves in the middle of a regional struggle.
The strong cultural unity of the region with Riau in the heart of this region never returned, and the line drawn by the British in 1819 remained, dividing the area into three new countries in 1965: Singapore, the Malaysian federation in the north, and Indonesia in the south.
Riau Islands are located on the International Shipping lane of Malacca Strait on the borders of Singapore, Malaysia, Brunei, Vietnam, Cambodia and Thailand. The province covers 252,602 square kilometers now under six main districts: Tanjungpinang City, Batam City, Bintan Regency, Karimun Regency, Natuna Regency and Lingga Regency.
