Sadani is one of two places in Tanzania with this name. This is the one in Tanga Region, near the coast.
In the East African campaign of World War I the British Royal Navy bombarded Sadani, first with the monitor on 26 July 1916 and then with the battleship on 3 August. This led the German East African authorities in Sadani to surrender to British land and naval forces.[1] [2]
Both namesakes are served by nearby stations on the national railway network.
