On 4 April 1721, soon after the death of Queen Louise, the king married Anne Sophie. He declined to make this marriage morganatic, although it was regarded highly scandalous by many subjects and foreign rulers alike, as it was outside the era's standards that royals marry regular noblewomen, their own subjects (thev requirements of so-called Ebenbuertigkeit).
