Sumatra Treaty

The second Sumatra treaty was signed between Great Britain and the Netherlands in 1871 . This was preceded by the first Sumatra treaty in 1824, in which the Netherlands undertook not to conquer Aceh on West Sumatra , but to leave it independent.

In this 2nd treaty the Netherlands was given a free hand to appropriate all of Sumatra without Great Britain opposing it. In return, the Netherlands renounced their colonial possessions on the so-called gold or slave coast in West Africa . These then became the British colony and what is now Ghana . As a direct consequence of the 2nd Sumatra Treaty, the Netherlands began to conquer Aceh in 1873. Eventually favor of the Netherlands outgoing war lasted nearly 30 years. It cost about 250,000 lives and the immense sum of around £ 50 million ; it was one of the most expensive colonial wars that were ever waged.
