History

The Medal for Zeal and Loyalty was established by Royal Decree in 1877, but it was discontinued in 1890. It was awarded to employees of low-ranking officials, clerks, and other employees of the Dutch Navy and Army in recognition of long and faithful service.

The Silver Medal features an obverse inscription that translates to "William III, King of the Netherlands, Grand Duke of Luxembourg,” and a reverse inscription that translates to "For Zeal and Loyalty."

There may be additional versions that vary in size or composition.
