died in 1884, and no royal babies were born from then until Wilhelmina gave birth to her only child, Juliana, in 1909. The Dutch royal house remained quite small until the later 1930s and the early 1940s, during which Juliana gave birth to four daughters. Although the House of Orange died out in its male line with the death of Queen Wilhelmina, it continued in the female line as can be seen in other modern european monarchies, the name "Orange" continues to be used by the Dutch royalty and as evidenced in many patriotic songs, such as "Oranje boven". The Netherlands remained neutral in World War I, during her reign, and the country was not invaded by Germany, as neighboring Belgium was. Nevertheless, Queen Wilhelmina became a symbol of the Dutch resistance during World War II. The moral authority of the Monarchy was restored because of her rule. After 58 years on the throne as the Queen, Wilhelmina decided to abdicate in favour of her daughter, Juliana.

The marriage of a member of the royal family to a German was quite controversial in the Netherlands, which had suffered under Nazi German occupation in 1940–45. This reluctance to accept a German consort probably was exacerbated by von Amsberg's former membership in the Hitler Youth under the Nazi regime in his native country, and also his following service in the German Wehrmacht. Beatrix needed permission from the government to marry anyone if she wanted to remain heiress to the throne, but after some argument, it was granted. As the years went by, Prince Claus was fully accepted by the Dutch people. In time, he became one of the most popular members of the Dutch monarchy, and his death in 2002 was widely mourned. On April 30, 1980, Queen Juliana abdicated in favor of her daughter, Beatrix. In the early years of the twenty-first century, the Dutch monarchy remained popular with a large part of the population. Beatrix's eldest son, Willem-Alexander, was born on April 27, 1967; the first
