Kionga-Triangle in an Old German Map (lower right side)

The Kionga Triangle was a small territory between German East Africa (largely overlapping present-day Tanzania) and the Portuguese colony of Portuguese Mozambique (present day Mozambique), totaling just 1000 km² (400 mi²).

Originally, the Germans established this as their outpost south of the Rovuma River; there was a settlement called Kionga (now Quionga), with a population of 4,000 inhabitants in 1910. However, in 1916 during World War I, the Portuguese occupied the territory. After the war, the Treaty of Versailles defined the border as running along the Rovuma, thus allotting the triangle to Mozambique. When Mozambique became independent on 25 June 1975, the Kionga remained with it as part of Cabo Delgado Province.

Postage stamps[edit]

Postage stamps were issued for Kionga during its occupation; for more detail, see postage stamps and postal history of Kionga.
