Eleonore is a refined and historic female given name, deriving from the Proto-Germanic elements 'helian' meaning 'sun' and '-hera' signifying 'army'. It was first popularized in France during the Middle Ages, carried by characters such as Eleanor of Aquitaine, a powerful noblewoman and duchess who played a significant role in politics and culture. Through her influence, the name gained prominence across Europe. In English, Eleonore is often associated with its variants like Eleanor or Eleanora, each offering a unique touch while retaining their shared rich history.
"Eleonore saw a peak in popularity around World War I, with over 20 births annually from 1914 to 1920. After the war, it remained relatively common until the late 1930s, then declined significantly until the late 1980s. It has seen some revival since the early 2000s."
