> Originally alphabets were written entirely in capital letters, spaced between well-defined upper and lower bounds. When written quickly with a pen, these tended to turn into rounder and much simpler forms, like uncials. It is from these that the first minuscule hands developed, the half-uncials and cursive minuscule, which no longer stay bound between a pair of lines.
> These in turn formed the foundations for the Carolingian minuscule script, developed by Alcuin for use in the court of Charlemagne, which quickly spread across Europe. Here for the first time it became common to mix both upper and lower case letters in a single text.
tl;dr: back to france, please.
