Solor is a volcanic island located off the eastern tip ofFlores island in theLesser Sunda Islands ofIndonesia, in theSolor Archipelago. The island supports a small population that has beenwhaling for hundreds of years. They speak the languages ofAdonara andLamaholot. There are at least fivevolcanoes on this island which measures only 40 kilometres (25 miles) by 6 kilometres (3.7 miles). The island's area is 226.34 square kilometres (87 square miles),^[1] and it had a population of 34,029 at the 2020 Census.^[2] The official estimate as at mid 2024 was 36,739.^[3]

The island is divided into threedistricts (kecamatan), tabulated below with their areas (in km²) and their populations at the 2010 Census^[4] and 2020 Census,^[5] together with the official estimates as at mid 2023.^[6][7][8] The entire island is administered by theEast Flores Regency.

West Solor District (kecamatan Solor Barat) is sub-divided into the town (kelurahan) of Ritaebang and fourteen rural villages (desa), as listed below with their areas and populations as at mid 2023.^[6]
South Solor District (kecamatan Solor Selatan) is sub-divided into seven rural villages (desa), as listed below with their areas and populations as at mid 2023.^[7]

In the 14th century, Solor was said to have been conquered by theMajapahit empire, and the island is mentioned in theNegarakertagama as a possession of Majapahit.^[12] In the 16th century, parts of the island were under the influence of theSultanate of Ternate. Since at least the 16th century, Solor played an important role in the trade ofsandalwood by acting as a popular safe harbor for ships engaged in the trade. This made Solor a relevant part of the mercantile networks of the wider region, a situation that would be reversed with the arrival of the Portuguese.^[12]

In 1520, the Portuguese established atrading post in the village ofLamakera on the eastern side of the island as a transit harbor betweenMaluku andPortuguese Malacca. In 1562,Dominican priests built a palm-trunk fortress whichJavanese Muslims burned down the following year. The fort was rebuilt from more durable materials and the Dominicans commenced theChristianisation of the local population.^[13] By 1590 the Portuguese and Christian population numbered about 25,000. There were, however, repeated displays of resistance against both the Portuguese and their religion; in 1598–1599, for example, the Portuguese required an armada of 90 ships to put down a Solorese uprising.^[14]

At this time, there was a conflict between the traders and the priests, so the traders left Solor and settled inLarantuka atFlores island. When the Dutch came in 1613, the priests surrendered at the first attack and were brought to Larantuka, too.

The Dutch kept the fort, but did not make a profit close to the Portuguese port. After two commanders defected to the Portuguese, they gave up Solor. In 1636 the Portuguese were attacked by the Dutch and had to abandon the fort. In 1646 the Dutch occupied the fort again. The first of the new commanders was suspended, because he married an indigenous woman. The second commander challenged the Portuguese commander to a duel and was slain. In 1648 the Dutch left and the Dominican priests returned.^[15]

In 1851 the Portuguese governorJosé Joaquim Lopes de Lima [pt] sold Solor and other areas of the Lesser Sunda Islands, which had been under Portuguese sovereignty, to the Netherlands for 200,000florins without authorization from Lisbon. Lisbon did not recognise the sale and had Lopes arrested. He died on the way back to Europe. From 1854, the agreements were renegotiated. The sale was finally confirmed in theLisbon Treaty and was ratified in 1859. Although the Dutch occupied the fort with a small force, the occupation was withdrawn again in 1869 for economic reasons but the official affiliation to the Netherlands remained.^[16] It was underJapanese occupation between 1942 and 1945, but along with the state of East Indonesia was later annexed into theUnited States of Indonesia with independence in 1949.
