How did Charlemagne command respect through his non - verbal presence

How did Charlemagne command respect through his non - verbal presence due to his dignified and strong presence.

Charlemagne was a tall man and while he had a bit of a belly, his overall body was well-shaped. He would usually smile and his long, healthy hair would provide a handsome appearance. Most people who met him described him as having a 'stately stature'.

Hence, his non-verbal presence automatically commanded respect wherever he went and even before he spoke.

Charlemagne lived in the 8th century but is probably the most famous King of his time. He is often referred as the "Father of Europe''
