The history of Banjarmasin is closely interwoven with its strategic location in the river delta and the rich natural resources that have made it a significant trading hub for many centuries. Often referred to as the "River Capital", the city was shaped by the influence of trade, politics, and a unique culture based on life by the water.
The foundation and establishment of the city began with a key event that took place on 24 September 1526. This date marks the victory of Prince Samudera, the heir to the Hindu kingdom of Negara Daha, in a struggle for power. Following his victory, achieved with the support of the neighbouring Sultanate of Demak, the prince embraced Islam, took the name Sultan Suriansyah, and founded the Sultanate of Banjar. The new city, which emerged at the confluence of the Kuin and Barito rivers, became its capital.
Key development factors defined the growth and prosperity of Banjarmasin. Firstly, its geographical position in the delta of the Barito and Martapura rivers made the city a natural port and a gateway for trade between the interior of Kalimantan and the rest of the world. Secondly, starting from the 17th century, the region became one of the largest suppliers of pepper in Southeast Asia, attracting merchants from China and European powers. Thirdly, its status as the capital of the powerful Sultanate of Banjar for centuries ensured the city's political influence and fostered economic growth.
The city's cultural and economic features are inextricably linked to its history. The early economy of Banjarmasin was entirely focused on river trade. In addition to pepper, gold, diamonds, rattan, and other jungle produce were exported from here. This characteristic shaped a unique "river" culture, a vibrant legacy of which are the famous floating markets (Pasar Terapung), which still exist today. The city became a melting pot where the traditions of the indigenous Dayak and Banjar peoples mixed with Javanese, Malay, Chinese, and European cultural influences.
