Oral traditions According to Sumbanese mythology, Flores and Sumba were once connected by the
Kataka Lindiwatu (in Sumba languages), an ancient stone bridge built by the native of Sumba and Flores. Due to the high level of socialization around the
Kataka Lindiwatu which connected both islands, civilization was thought to arise from around those regions (which nowadays correspond to northern Sumba and to part of
East Sumba regency territory). This story belongs to the Sumba oral traditions as was written down by Umbu Pura Woha (2007) in his book (). The megalithic remains found on Sumba Island include dolmen tombs, upright stones, megalithic statues, stone enclosures, and levelled terraces. The Sumba megalithic tradition itself was characterized by the old megaliths built and carved with high quality standards. Some ancient tools are also found on the island. Notable findings are quadrangular
adzes unearthed in the
Anakalang area (a cultural region of Anakalang Sumba, a subethnic group of Sumba people). One significant archaeological discovery was that of the urn burial site in Melolo in the 1920s, dated around 2,870
BC.
Javanese power Around the 12th century, the kingdom of
Singhasari in eastern Java gained more power over the maritime Southeast Asian territory after the kingdom defeated the
Mongols; since then, this kingdom evolved into the
empire known as
Majapahit. Sumba Island was a subject of Majapahit's dominion, and the word "
Sumba" itself was first officially used during the Majapahit era (mentioned in the ancient Javanese manuscripts of
Pararaton and
Sumpah Palapa oath of
Gajah Mada); the word itself was thought as the closest substitution in Javanese for the native name of the island according to native Sumba people, which is
Humba or
Hubba. It is thought that Javanese people arrived on Sumba Island via the
Madura and
Kangean route, based on analysis of the DNA of chicken species on Sumba that are only
endemic in the eastern parts of Java and its neighbouring islands (which in this case is probably Kangean Island).
European colonial period In
1522, the native Sumba came into contact with the Europeans (Portuguese) who arrived on the island by ship to explore the natural resources of the island. Later, it also attracted the
Dutch VOC to the region from the
1600s. Historically,
sandalwood was the main commodity exported to Europe from this island, thus the Sumba Island was referred to colloquially as the
Sandalwood Island or
Sandel Island (in English). In
1866, governance over the island of Sumba was transferred to the
Dutch East Indies colonial power. The well-known
Evangelism of the natives of Sumba Island was started in 1886 by the Dutch under the Douwe Wielenga Jesuits' missionary program in the district of Laura in
West Sumba. ==Geography, climate and ecology==
