Princess Louise of Prussia, later Grand Duchess of Baden (1838-1923) was the daughter of William I, King of Prussia and German Emperor. Her long life spanned the year of revolutions in 1848 and the immediate aftermath of the First World War. She took little interest in the political matters of the day and, apart from being an ardent supporter of Roman Catholics in Germany, rarely made her views known. Yet for several decades she played a supportive role where her family was concerned, particularly involving herself in charitable works during the Franco-Prussian war of 1870. She and her husband Frederick, Grand Duke of Baden (1826-1907), had three children and it is from their daughter Victoria, consort of King Gustav V, that the Swedish royal family are descended. This concise account examines her life and times.
