The first official postal service in Nauru was set up by the German colonial office in 1908, as part of the Marshall Islands. When this German colony was occupied by Australia in 1914 it was felt that Nauru should have its own issues. At first they used the “N W Pacific Islands” overprints on Australian stamps, but the British stamps overprinted “NAURU” were released as and when those became exhausted. Those postmarked 2 Sept were allegedly all cancelled to order (ie in the typically Australian collectors’ packs); the earliest commercial use appearing to be October 1916. It is reported that the decision to make the island a British Mandate area, and to use overprinted British stamps, on the surface rather a strange decision, was made to avoid the political sensitivities which could have arisen if Australian (or other) stamps had been so overprinted whilst the island’s future was being decided.
The overprinted British stamps continued in use until 1924 when it was finally decided that the country should be under an Australian Mandate, and a replacement definitive set was issued.

These came from a single printing, and the next printing reverted to the original format of the overprint; the 1½d and 2d die II in the 12½mm overprint came only from the final printings after the 13½mm version had been issued. It has been alleged that one reason for the reversion to the 12½mm version (at the foot of the stamp) was that King George V (a keen stamp collector) objected to the overprint falling on his face.
