Leopold III of Belgium
On his return to Belgium in 1950, Leopold was met with one of the most violent strikes in the history of Belgium. The country stood on the edge of civil war. Belgian banners were replaced by Walloon flags in Liège and other municipalities of Wallonia. To avoid tearing the country apart, and to keep the monarchy, Leopold decided on 1 August 1950 to withdraw in favour of his 20-year-old son Baudouin.
