According to traditional accounts, the dynastic line of Amabi was related to the leading West Timorese kingdom of Sonbai, and to the Tetun kingdom of Wehali in south-central Timor. Through the effort of Dominicanmissionary in the early 17th century, it was tied to Portuguese interests on Timor. In 1655, however, the king of Amabi, together with that of Sonbai, switched sides and made an alliance with the Dutch East India Company, which had established itself in Kupang two years previously. The Dutch and their new allies soon proved particularly unsuccessful against the Portuguese clients on Timor. In the fall of 1657 the king of Amabi was killed by the latter at the battle of Gunung Mollo in the interior of West Timor. In September 1658 a large part of the Amabi population fled to Kupang in order to escape their enemies, and were permitted by the Dutch to settle close to the European fort. Part of the population stayed in the interior. This congregation, Amabi Oefeto, was subjected to the Amarasi principality, which in turn was a vassal of Portugal. The Amabi community of refugee turned out to be loyal subordinated allies of the VOC. Together with the principalities of Kupang, Sonbai Kecil, Amfoan and Taebenu, they constituted the backbone of Dutch strategy on Timor. During much of the 17th and 18th centuries they waged small-scale warfare against the Portuguese client principalities, in particular Amarasi. This role was less crucial after 1749, when the Portuguese grip on West Timor was lost. Still, in the late 19th century Amabi was considered the most powerful among the local allies of the Dutch colonial government. When the Dutch implemented full control over the inland territories of West Timor in the early 20th century, the protective role of the small Amabi principality became obscure. Through an administrative reorganization, Amabi was merged with four other principalities in 1917, into the zelfbesturend landschap of Kupang. Up to 1962, the ex-ruler of Amabi held the function of fettor of his old lands. In that year, the Indonesian republican government definitely abolished the system of hereditary princes. In 1949, the population of Amabi stood at 10,767 persons.
