The 2017 Luxembourg 2 euro commemorative coin honours Grand Duke Guillaume III, a significant figure in the nation’s constitutional history. The national side features a profile portrait of the Grand Duke, rendered with formal precision to commemorate his role as the sovereign of Luxembourg from 1849 until 1890. His reign was marked by the establishment of the 1868 Constitution, which remains a cornerstone of the country's modern democratic framework. By depicting the Grand Duke, the design serves as a tribute to the continuity of the Luxembourgish monarchy and its enduring influence on the state's political development. This commemorative issue was released as a standard circulation coin in 2017.
