Nauru was annexed by Germany in 1888 and incorporated into Germany Islands Protectorate. The arrival of the Germans ended the civil war, and kings were established as rulers of the island. The most widely known of these was King Auweyida. Christian missionaries from the Gilbert Islands arrived in 1888. The Germans ruled Nauru for almost three decades.
Phosphate was discovered on Nauru in 1900 by the 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. Australia, New Zealand and the United Kingdom signed the Nauru Island Agreement in 1919, creating a board known as the British Phosphate Commission (BPC) that took over the rights to phosphate mining.
