Germany gains the small but strategic Heligoland archipelago, which its new navy needs to control the new Kiel Canal and the approaches to Germany's North Sea ports, under terms of the Heligoland–Zanzibar Treaty (also known as the Anglo-German Agreement of 1890) signed on July 1, 1890, between the German Empire and the United Kingdom.

In exchange, Germany gives up its rights in the Zanzibar region in Africa, allowing Zanzibar to provide a key link in the British control of East Africa.
