The Kiautschou Bay Leased Territory (German: Deutsches Pachtgebiet Kiautschou), also known as the Jiaozhou, Kiaochau, Kiaochow, Kiauchau, and Kiao-chau Bay Concession, was a German leased territory in Imperial and Early Republican China from 1898 to 1914. Covering an area of 552 km (213 sq mi), it centered on Jiaozhou Bay (Kiautschou-Bucht) on the southeastern coast of the Shandong Peninsula. The administrative center was at Qingdao (Tsingtau). It was operated by the East Asia Squadron of the Imperial German Navy. The Russian Empire resented the German move as an infringement on Russian ambitions in the region.
