Carolus is a Latin origin given name, meaning 'strong' or 'freeholder'. It was commonly used among early Christians due to its association with the Roman god Mars and the military strength it implied. The name Carolus is also believed to have been derived from 'Karl', an Old German word for 'freeholder' or 'strong'. Notable figures with this name include Carolus Linnaeus, a Swedish botanist known as the 'father of modern taxonomy,' and Carolus Magnus, better known as Charlemagne, the first emperor of the Holy Roman Empire. Despite its historical significance, Carolus is not frequently used today.
Carolus had an average of one birth every two years during this period.
