Nicknames The "Iron Duke" related to Wellington's political, rather than to his military, career. Its use is often disparaging. It is possible the term became more commonly used after 1832 when Wellington had metal shutters installed at Apsley House to prevent rioters breaking the windows. The term may have been made increasingly popular by Punch cartoons published in 1844–45.
