SUMBAWA (Dutch Soembawa), one of the Little Sunda islands in the Dutch East Indies, east of Lombok, from which it is separated by the narrow Alas Strait.
The deep bay of Sale or Sumbawa on the north divides the island into two peninsulas, and the isthmus is further reduced by the narrower Bay of Chempi on the south.
Tambora, forming a minor peninsula east of Sumbawa Bay, is said to have lost a third of its elevation in the eruption of 1815, but is still 9055 ft.
Politically Sumbawa, with its four independent states, belongs to the confederated states of the government of Celebes and its dependencies, a situation to be explained by the fact of the old supremacy of the Macassaresi over Sumbawa, Flores and Sumba.
The independent states are Sumbawa proper, Dompo, Sangar and Bima.
