From the Latin urbanus  (derived from urbs, meaning city) and the French urbain to mid-16th century English  word urban and into urbane (a modern sense of savoir faire - no doubt fostered by city dwellers at the time - believing that living in the city made one more suave than rural life). 

The difference between urban and urbane is that urban refers to the areas within a city, while urbane means having refined and polite manners, which was originally beliefs to be a product of city life, rather than rural living.
