What was hard for George to do when he became king?, Context: In the words of Labour Member of Parliament George Hardie, the abdication crisis of 1936 did "more for republicanism than fifty years of propaganda". George VI wrote to his brother Edward that in the aftermath of the abdication he had reluctantly assumed "a rocking throne", and tried "to make it steady again". He became king at a point when public faith in the monarchy was at a low ebb. During his reign his people endured the hardships of war, and imperial power was eroded. However, as a dutiful family man and by showing personal courage, he succeeded in restoring the popularity of the monarchy.
