Located in old British Central Africa:
Malawi was part of the Federation of Rhodesia and Nyasaland
during the 1950s and 1960s, which also contained Northern Rhodesia, now Zambia, and Southern Rhodesia, later just Rhodesia, now Zimbabwe.
Description of the flag:
The Nyasaland Protectorate, now Malawi, which
was formerly known as British Central Africa has a badge which shows a
tree on a diagonal yellow, white and black background.
If accurate, the badge must have been superceded later. By at least the late 1930s Nyasaland's badge was a roaring leopard on a rock with, as a chief, a gold on black image of a rising sun.
When the first explorers arrived in what is now Malawi, they asked the inhabitants what the big lake was called. 'Nyasa' they were told. So the lake was christened Lake Nyasa - which it will not surprise you to learn means 'Lake Lake'. 'Malawi', incidentally, means 'flaming waters' - an allusion to the reflections of the setting sun on Lake Nyasa. (Ironically, it is only possible to observe this phenomenum to best advantage from the Mozambique bank of the lake.) This symbolism also appears on the Malawian flag, which features a red sun.
