Lothar, a name of Germanic origin, is composed of two elements: 'hild' meaning 'battle', and 'bera' meaning 'bearer'. This powerful combination gives Lothar its meaning, 'bearer of the army'. The name has a rich history, particularly in royalty, with Lothar I being the first Holy Roman Emperor to be crowned by the Pope himself. Throughout the Middle Ages, several members of the Carolingian dynasty bore this strong and distinctive name.
"Lothar experienced a surge in popularity with 10 births in 1929, but overall, it was relatively uncommon throughout the century."
