Phosphate was discovered on Nauru in 1900 by the prospector Albert Fuller Ellis. The Pacific Phosphate Company began to exploit the reserves in 1906 by agreement with Germany, exporting its first shipment in 1907. In 1914, following the outbreak of World War I, Nauru was captured by Australian troops. In 1919 it was agreed by the Allied and Associated Powers that His Britannic Majesty should be the administering authority under a League of Nations mandate. The Nauru Island Agreement forged in 1919 between the governments of the United Kingdom, Australia, and New Zealand provided for the administration of the island and extraction of the phosphate deposits by an intergovernmental British Phosphate Commission (BPC). The terms of the League of Nations mandate were drawn up in 1920.
