Carola is of Italian origin, derived from the Latin word 'carulus', meaning 'little dear' or 'hare'. It is a feminine given name that has been used since medieval times. The name gained popularity in the 19th century and remains in use today, particularly in Italy and other European countries.
"Carola saw its highest popularity between 1945 and 1966, with over 20 births each year from 1945 to 1957. After a decline in the late 1960s, it picked up again in the late 1990s and early 2000s, though never reaching previous heights."
