Austrian colonization of the Nicobar Islands
The Austrian colonization of the Nicobar Islands (German: Nikobaren, renamed to the Theresia Islands [Theresia-Inseln]) involved a series of three separate attempts by the Habsburg monarchy, and later the Austrian Empire, to colonize and settle the Nicobar Islands. Only the first of these, launched in 1778, was successful. The second attempt was canceled, and the third, in 1886, was abandoned due to prior colonization by the British in 1868. The Nicobar Islands had been previously colonized by the Danish in 1756; the Danes abandoned the islands after multiple outbreaks of malaria, but continued to lay formal claim to the islands until 1848.
