Upon liberation of Luxembourg in 1944 a chargé d'affaires was briefly resident in Luxembourg, followed by a resident military mission with diplomatic responsibility reverting to Brussels; but a resident head of mission was soon restored, in 1949.
After Luxembourg's release from occupation in 1944, a temporary representative lived in Luxembourg for a short time before a military team with diplomatic authority returned to Brussels. Later, in 1949, a permanent representative was reestablished in Luxembourg.
