Why did bach get arrested by the duke from bach's fight for freedom?

Johann Sebastian Bach was arrested by Duke Wilhelm Ernst of Weimar in 1717 due to a dispute over Bach's desire for greater artistic freedom and his wish to leave his position as court musician. The duke had refused to grant Bach permission to leave, leading to tensions between them. As a result, Bach was imprisoned for several weeks, an event that ultimately spurred him to seek better opportunities elsewhere. This incident highlights Bach's commitment to his artistic integrity and autonomy.
