The misleading name of the contract was introduced by former Chancellor Otto von Bismarck, who was preparing to attack his despised successor, Caprivi, to conclude an agreement reached by Bismarck himself during his management. However, Bismarck`s nomenclature implied that Germany had traded an African empire for a small Helgoland (pants for button).  This was taken with zeal by imperialists who complained of “treason” against German interests. Carl Peters and Alfred Hugenberg advocated the creation of the All-German Association, which took place in 1891.  The Helgoland-Zanzibar Treaty (German: Helgoland-Zanzibar Treaty, also known as the 1890 Anglo-German Agreement) was an agreement signed on 1 July 1890 between the German Empire and Great Britain. Anglo-Portuguese relations in Africa had been strained by the British ultimatum of 1890, which had prevented Portugal from joining its colonies in Angola and Mozambique beyond Malawi. In 1891 Zambia and Zimbabwe led to the Anglo-Portuguese Treaty and, by an Anglo-German agreement in 1898, that if Portugal abandoned its African colonies, Germany could extend German-South Africa northward and Germany to eastern Africa, while Britain would extend its South African territory to the east and the Atlantic islands of Portugal.

 The agreement gave Germany control of the Caprivi Strip (a headband that allowed South-West Africa of Germany to access the Zambezi River), the strategic island of Helgoland in the North Sea and central East Africa (Tanganjika). In return, Germany recognized British authority in Zanzibar.
