Mnyaka Sururu Mboro is still driven by the promise he gave his grandmother when he left Tanzania for Germany almost 50 years ago: to bring back for a proper burial the head of a local chieftain, killed in 1900 by German colonists for opposing their rule in Africa.
Mboro, now 73, is from the same area near Mount Kilimanjaro that was once ruled by Mangi Meli, king of the Wachaga people. From 1885 to 1919, the region was part of German East Africa, a huge colony almost three times the size of present-day Germany.
