The Arabian was first sighted in Arabia near the Arabian Peninsula. they come in a large veriety of colors such as... black, grey, bay, brown, etc,...
And was a very good desert horse because it could go for long periods of time without water, and could run long distances without getting over heated. The Arabian was also a very good warhorse 'cause it was always ready to move and obey orders.
And if we were to go back to the time when we didn't use cars, guns, and tanks, but rather used horses, spears, and swords for weapons, because the Arabic people relied on their horses so much, if you did ,by chance, find one for sale it would, most likely, be a very old, sick, horse, or it's owners very desperate.

And when the Arab was brought to England and bred with the english race horses the offspring of these racers would run at a full gallop, unlike their racing ancesters who paced rather than galloped.
