This medal was created by request to replace a distinction from the Belgian authorities by one from the Arenberg family.

While as a general principle the medal is awarded in recognition of scientific, historical, artistic and literary work, it is primarily awarded to the many people who continue to render eminent service to the House of Arenberg.
