In May 1935, soon after the French government had agreed the Franco-Soviet Treaty of Mutual Assistance with the Soviet Union government, Trotsky was officially told that he was no longer welcome in France. After weighing his options, Trotsky applied to move to Norway. After obtaining permission from then Justice Minister Trygve Lie to enter the country, Trotsky and his wife became a guest of Konrad Knudsen at Norderhov, near Hønefoss, and spent over a year living at Knudsen's house, from 18 June 1935 to 2 September 1936, although Trotsky was hospitalized for a few weeks at the nearby Oslo Community Hospital from 19 September 1935.
