West Nusa Tenggara (Indonesian: Nusa Tenggara Barat – NTB) is a province of Indonesia. It comprises the western portion of the Lesser Sunda Islands, with the exception of Bali which is its own province. Mataram, on Lombok, is the capital and largest city of the province. It shares maritime borders with Bali to the west and East Nusa Tenggara to the east. The 2010 census recorded the population at 4,500,212; the total rose to 4,830,118 at the 2015 census and 5,320,092 at the 2020 census;[5] the official estimate as at mid 2022 was 5,473,671.[6] The province's area is 20,153.15 km2. The two largest islands by far in the province are Lombok in the west and the larger Sumbawa island in the east.


Pre-Islamic period

Based on analysis of prehistoric objects found such as complex sarcophagi, decorated stoneware, machetes, and axes, West Nusa Tenggara had been inhabited by people from Southeast Asia.

The natives in this region are called the Sasak people, most of whom live on the island of Lombok, on the island of Sumbawa the indigenous people are divided into two groups, ethnic Sumbawa (Samawa) and Bima. However, with the wave of migrants from Bali, Makassar, Java, Kalimantan, Nusa Tenggara, Maluku and East Nusa Tenggara, the indigenous people now remain in the interior.

The region can was part of the Majapahit Empire during its height in the 14th century conquering all the kingdoms located on the islands of both Lombok and Sumbawa. In the book Negarakertagama by Mpu Prapanca in 1365, it was written that West Lombok was named "Lombok Mirah" and East Lombok was named "Sasak Adi", Taliwang, Dompo (Dompu), Sape, Sanghyang Fire, Bhima (Bima), Seram (Seran) and Hutan Kedali (Utan).[7]

Islamic period

In the early reign of the kings in West Nusa Tenggara, the influence of Hinduism was very strong, but with the collapse of the Majapahit Empire, the influence of Hinduism began to decrease with the onset of the influence of Islam in the coastal communities.

The creation of the Demak Sultanate in Central Java had a huge impact on the spread of Islam in West Nusa Tenggara. The influence of Islam in West Nusa Tenggara was generally brought by the Malays. The influence of Islam in Bima was supported by King I Maliingkaang Daeng-Mannyonriq of Makassar, who was then known as Karaeng Matoaya who played an important role in the spread of Islam in the region.

The influence of Islam in the Bima Sultanate emerged during the reign of King Manuru Salehi around 1605 and began to grow rapidly during the reign of King Abdul Kahir. King Abdul Kahir is also known as the Sultan of Bima because he was the king who first embraced Islam in Bima, beginning a new era, separate from the previous Bima kings who embraced Hinduism. Islam became the official religion of the kings in West Nusa Tenggara.[8]

Colonial period

The Europeans who first came to Nusa Tenggara were the Portuguese who landed on the island of Solor and Timor in 1605. At the same time the Dutch also came to the island of Hitu and Ambon, in the Malukus. The first Dutch ship that entered the area was the Ter Ver which docked in Kupang in 1611. The arrival of the Dutch-led to a long dispute between the Portuguese and the Dutch in Nusa Tenggara. The Dutch provided assistance to the local kings who resisted the Portuguese. The Netherlands then expanded its influence in Nusa Tenggara, to make a variety of agreements with small kings around the island of Sumbawa.

The arrival of the Dutch colonial administration greatly impacted Indonesian society, with the decline of the Sultanate of Gowa in the 17th century. Gowa nobility who did not submit to the colonial government fled from Makassar and built pockets of resistance in West Nusa Tenggara. To combat the resistance, the colonial government began to concentrate power in West Nusa Tenggara. This was reinforced by the emergence of Lombok for international trade, so the desire of the Dutch to rule West Nusa Tenggara become stronger.

The Dutch colonial government sent Stephen van Hegen for a close look at the Bima Sultanate in 1660. The arrival of the Dutch, influenced the political and economic situation in the area. In 1669, the Government of the Bima Sultanate led by Sultan Ambela Abdul Khair Sirajuddin, made peace and friendship ties with the colonial government with the agreement that:

The agreement with the Sultan of Bima and Dompu recognized the existence of the Dutch colonial power. The Netherlands sought to consolidate its control by blocking the Bima port to prevent the arrival of aid from Makassar or other foreign countries. The effort was done so that the existing ports in Bima and Lombok would not fall into British hands.

Because of Dutch supremacy in the region the king and the people in the region could not move freely. This situation became worse with the eruption of Mount Tambora on April 5, 1815, which shook the entire region, and the consequences could be felt throughout the Moluccas, Java, Sulawesi, Sumatra, and Kalimantan. Mount Tambora's eruption resulted in the disappearance of the two kingdoms of Tambora and Papekat. More than 10,000 people were killed.


West Nusa Tenggara province previously had been part of the State of East Indonesia with the creation of the United States of Indonesia, and had been part of the province of the Lesser Sunda Islands (Nusa Tenggara) after the recognition of Indonesian sovereignty.

The province of West Nusa Tenggara was created with the enactment of Law No. 64 of 1958 Dated August 14, 1958, on the Establishment of the new provinces of Bali, West Nusa Tenggara and East Nusa Tenggara, with its first governor, AR. Moh. Ruslan Djakraningrat.

Two additional regencies were created - West Sumbawa from part of Sumbawa Regency on 18 December 2003, and North Lombok from part of West Lombok Regency on 24 June 2008.
