Princess Märtha of Sweden
Following a year-long engagement, she married Crown Prince Olav in Oslo Cathedral on 21 March 1929. Märtha's was the first royal wedding in Norway in 340 years. The marriage is widely believed to have been a success due in large part to their genuine mutual love. They had three children: Ragnhild (1930–2012); Astrid (b. 1932); and the much awaited heir, Harald (b. 1937).
