Frederik became king on his father's death in April 1947. During Frederik's reign, Danish society changed rapidly, the welfare state was expanded and, as a consequence of the booming economy of the 1960s, women entered the labour market. The modernization brought new demands on the monarchy and Frederik's role as a constitutional monarch. Frederik died in 1972, and was succeeded by his eldest daughter, Margrethe II.
