A chief officer or commander of a centaine (a hundred men) in medieval France or a leader of a hundred soldiers.
From Old French 'centenier,' derived from 'centaine' (a group of a hundred), which comes from Latin 'centum' (hundred). Used in feudal and medieval administrative contexts.
The centenier was France's version of the English 'constable'—different titles for the same basic job: keep 100 people organized and follow orders—showing how parallel governmental systems evolved across medieval Europe.
