first Boer Republic was established in 1795 out of the district of
Graaff-Reinet followed a few months later when the district of
Swellendam declared itself a republic. Both republics were later
conquered after the British took control of the Cape from the Dutch
power. A lot of folks often have no awareness of this important fact
often erroneously presuming that the first Boer Republics arose during
The Great Trek. This fact is important because it is a stark example
demonstrating that the Boers have had a long running desire for
independence in Africa while the Cape Dutch did not. I have mentioned
these first Boer Republics before, but recently found a map outlining
the areas where they were as someone made a map of the Graaff-Reinet
& Swellendam districts during the era of Dutch / VOC rule up to
1795. Theses districts were on the Cape frontier where the Boers emerged
[ from the Trekboers ] starting just a few decades after the initial
arrival of the VOC at the Cape & where the Boer people lived
until the Great Trek of the early to mid 19th cent took them across the
Orange [ Gariep ] River & then the Vaal River.
The red / white & blue horizontal tri color flag was used for both republics of the Cape frontier.
