I just checked Wikipedia whether Pepsi really does not brand itself as "Cola" anymore and decided to click on two more links, just to find out that Coca-Cola only exists, because a racist got stabbed unsuccessfully:
John Stith Pemberton [...] was an American pharmacist and Confederate States Army veteran who is best known as the inventor of Coca-Cola. [...]
He suffered from a sabre wound sustained in April 1865 [...] He began to experiment with various painkillers and toxins. In the end, after development of an earlier beverage blending alcohol and cocaine, this led to the recipe that later was adapted to make Coca-Cola.
