III. Friedrich Wilhelm'la kim evlendi?

III. Friedrich Wilhelm (Almanca: Friedrich Wilhelm III.) (3 Ağustos 1770 – 7 Haziran 1840), 1797-1840 yılları arasında Prusya kralı.

Louise of Mecklenburg-Strelitz (Luise Auguste Wilhelmine Amalie; 10 March 1776 – 19 July 1810) was Queen of Prussia as the wife of King Frederick William III. The couple's happy, though short-lived, marriage produced nine children, including the future monarchs Frederick William IV of Prussia and William I, German Emperor.

Her legacy became cemented after her extraordinary 1807 meeting with French Emperor Napoleon I at Tilsit – she met with him to plead unsuccessfully for favorable terms after Prussia's disastrous losses in the War of the Fourth Coalition. She was already well loved by her subjects, but her meeting with Napoleon led Louise to become revered as "the soul of national virtue". Her early death at the age of thirty-four "preserved her youth in the memory of posterity", and caused Napoleon to reportedly remark that the king "has lost his best minister". The Order of Louise was founded by her grieving husband four years later as a female counterpart to the Iron Cross. In the 1920s, conservative and nationalist German women founded the Queen Louise League.

Countess Auguste von Harrach zu Rohrau und Thannhausen, Princess of Liegnitz (30 August 1800 – 5 June 1873), was the second wife of King Frederick William III of Prussia. At the time of their marriage, the House of Harrach was still not recognized as equal for dynastic purposes. Later, in 1841, a year after Frederick William's death, they were officially recognized as a mediatized family (a family that once ruled a territory with Imperial immediacy within the Holy Roman Empire), with the style of Illustrious Highness, which allowed them to officially have equal status for marriage purposes to those reigning and royal families. Thus, in 1824 when the marriage occurred, it was treated as morganatic, so she was not named Queen, but was given the title Princess von Liegnitz and Countess von Hohenzollern. Frederick reportedly stated that he did not wish to have another queen after Queen Louise.
