Under the terms of the constitution attributed to Servius Tullius, a sixth-century B.C. King of Rome, the army and the people were divided into six classes, membership of each was based originally on the amount of land held and latterly on their wealth in monetary terms.

English first adopted the word in this antiquarian sense which provided the basis for the modern application to "social class", but its widespread use in the language probably began in the sense "group of pupils".

Here is a term with a slight touch of snobbery about it, because the roots of classic are in the Latin word classicus, which meant "of the first rank" and was applied to the upper and better classes of Rome.
