Postage stamps were a tool of imperialism in Southern Africa, deepley connected to state building. This can exemplarily well be demonstrated with the case of Transvaal philately.
Pretoria was founded by and named after Andries Pretorius, ending a migration that his ancestor had once begun in Schüttorf. His son Martinus Wessel Pretorius made it 1860 the capital of the racist settler republic Zuid Afrikaanse Republiek (ZAR). A few thousand members of cattle farmers survived by guns from the Cape Colony and enforced labour wrenched from at least the double amount of Africans. The ZAR turned into a state only by the efforts of Friedrich Jeppe, who cartographed the country, collected and published the laws, tidied the finances and, as part of the latter, finally established a postal system with the help of Adlph Otto from Güstrow in Mecklenburg.
