The quagga is a now-extinct subspecies of the plains (Burchell’s) zebra. According to Wiki, it “was once found in great numbers in South Africa‘s Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider, and the hindquarters were a plain brown. The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga’s call.”

How were they related to horses, and other zebras? This diagram shows how horses, asses (donkeys) and zebras split off in their evolution (click to enlarge):

If you’d like a more technical answer, have at it: “A rapid loss of stripes: the evolutionary history of the extinct quagga“, Leonard et al., Biology Letters: Biol. Lett. (2005) 1, 291-295 DOI: 10/1098/rsbl.2005.0323.
Extinction may not be forever, though; the Quagga Project aims to recreate the quagga through selective breeding of Plains zebras, and over 120 foals have been bred towards this goal. A colt named Henry, foaled in 2005, is their most quagga-esque foal so far and is the product of three generations of careful breeding.
He’s not quite there yet; there is still some striping on his hocks, a feature not exhibited on skin specimens in museums, so the quest continues. Similar “breeding back” attempts have also been made with tarpans, which I’ll feature in a future post (along with onagers and kulans). Need a reason to keep you coming back, after all…
Cryptomundo has a few entries on quaggas.
Yup, we got stamps.
