On September 15, 1973 the then Crown Prince Carl Gustaf ascended to the throne and became King Carl XVI Gustaf of Sweden - Sweden's head of state. This means that the King this year has been the head of state in 40 years.
In conjunction with this year's anniversary published book "Mina 40 år för Sverige" ("My 40 years for Sweden"). The King picked out about 300 pictures from his years as head of state and provided them with personal captions.
"One of the best things about significant years is that they provide the opportunity to look forwards as well as backwards. Forty years is a very long time, and so much has happened. I was a relatively young man of 27 when I ascended to the throne, and I saw the world through the eyes of a 27-year-old. Now, 40 years later, I have a certain amount of experience to draw on. And the world around us has changed on many levels and in many different ways; even in terms of the proximity of the immediate family circle, in Sweden and in the world. It is sometimes said in jest that everything was so much better before, but that simply isn't true. In many ways, the world has become a better place in which to live for most people, but there is still a great deal of poverty and need in the world."
