Kiautschou Bay concession
The German protectorate of the Kiautschou Bay concession in Jiaozhou Bay, China fully implemented Georgist policy. Its sole source of government revenue was the land value tax of six percent which it levied in its territory. The German government had previously had economic problems with its African colonies caused by land speculation. One of the main reasons for using the land value tax in Jiaozhou Bay was to eliminate such speculation, which the policy achieved. The colony existed as a German protectorate from 1898 until 1914, when seized by Japanese and British troops. In 1922 the territory was returned to China.
