(Also known as Caroline miniscule). A calligraphy script in use in Europe from the 8th through the 11th centuries. Carolingian minuscule was created partly under the patronage of the Emperor Charlemagne (hence Carolingian). It was more legible than earlier scripts and offered new features, such as lower-case letters and spaces between words. Web resource here.
