George VI was the unexpected king. https://www.gresham.ac.uk/lectures-and-events/king-george-vi
As the second son of George V, he had no reason to believe, until less than a month before his accession, that he would succeed to the throne. He reigned in an atmosphere of almost perpetual crisis - confrontation with the dictators, war, decolonisation and the difficult economic problems of the immediate postwar years. His human qualities reinforced the spirit of social solidarity which helped Britain to victory in war and recovery in peace.
