Wilhelmina was Queen of the Netherlands from 1890 until her abdication in 1948. She reigned for nearly 58 years, longer than any other Dutch monarch. Her reign saw both World War I and World War II, as well as the Dutch economic crisis of 1933.
The only child of King William III of the Netherlands and Emma of Waldeck and Pyrmont, Wilhelmina ascended to the throne at the age of 10 after her father's death in 1890, under her mother's regency. After taking charge of government, Wilhelmina became generally popular for maintaining Dutch neutrality during the First World War and solving many of her country's industrial problems. By that time, her business ventures had made her the world's first female billionaire in dollars. She went on to ensure that her family was one of seven European royal houses remaining in existence.
Following the German invasion of the Netherlands in 1940, Wilhelmina fled to Britain and took charge of the Dutch government-in-exile. She frequently spoke to the nation over radio and came to be regarded as a symbol of the resistance.
