Question: How many children did King Casimir IV have when he purchased Malbork Castle from the Teutonic Knights? Passage 1:It was originally constructed by the Teutonic Knights, a German Catholic religious order of crusaders, in a form of an Ordensburg fortress. The Order named it Marienburg in honour of Mary, mother of Jesus. In 1457, during the Thirteen Years’ War, it was sold by the Bohemian mercenaries to King Casimir IV of Poland in lieu of indemnities and it since served as one of the several Polish royal residences and the seat of Polish offices and institutions, interrupted by several years of Swedish occupation, and fulfilling this function until the First Partition of Poland in 1772. From then on the castle was under German rule for over 170 years. Following Germany's defeat in World War II in 1945, the land was assigned to Poland by the Allies. Heavily damaged, the castle was renovated under the auspices of modern-day Poland in the second half of the 20th century and most recently in 2016. Nowadays, the castle hosts exhibitions and serves as a museum.
 Passage 2:The far-right tradition in France finds its origins in the Third Republic with Boulangism and the Dreyfus Affair. The modern "far right" or radical right grew out of two separate events of 1889: the splitting off in the Socialist International of those who chose the nation and the culmination of the "Boulanger Affair", which championed the demands of the former Minister of War General Georges Boulanger. The Dreyfus Affair provided one of the political division lines of France. Nationalism, which had been before the Dreyfus Affair a left-wing and Republican ideology, turned after that to be a main trait of the right-wing and, moreover, of the far right. A new right emerged, and nationalism was reappropriated by the far right who turned it into a form of ethnic nationalism, itself blended with anti-Semitism, xenophobia, anti-Protestantism and anti-Masonry. The Action française, first founded as a review, was the matrix of a new type of counter-revolutionary right-wing, and continues to exist today. During the interwar period, the Action française (AF) and its youth militia, the Camelots du Roi, were very active. Far right leagues organized riots.
 Passage 3:The co-founder and executive director is Daniel B. Fisher, now a board-certified psychiatrist. A graduate of Princeton University, he completed a PhD in biochemistry at the University of Wisconsin, medical training at George Washington University, and a psychiatric residency at Harvard Medical School. While working as a biomedical researcher at the National Institute of Mental Health before he was a psychiatrist, Fisher had a psychotic episode including hallucinations and delusions. After three months at Bethesda Naval Hospital at age 25, which included forced seclusion and antipsychotic haloperidol, he was discharged with a diagnosis of schizophrenia. He was involuntarily hospitalized three times. He reports being influenced by those who were able to show they cared about the person inside and gave him hope that he might some day recover. He went on to become a psychiatrist. He was told during psychiatric training that "You can’t talk to an illness" but believed that talking to the person inside is a key method for building trust and recovery. He has since worked as a psychiatrist in hospitals and clinics, while also being a part of the consumer movement. He said that a very significant part of the reason for becoming a psychiatrist was wanting to bring to the field what he wished had been there when he was going through psychosis He was a member of the White House Commission on Mental Health, 2002-03.
