During the 1903-1904 school year at the Imperial Theatrical School in Russia, Vaslav Nijinsky was expelled for being accused of throwing a homemade dart (made of paper) at a government official. The government official stopped the carriages that were transporting the students, pointed out Nijinsky to a policeman, and ordered him to be expelled.
While Nijinsky’s peers denied everything, he had already received bad marks for conduct and the Administration ordered Nijinsky to be permanently expelled.
His mother begged Inspector Pisnyatchevsky to forgive Nijinsky, so the punishment was lessened to a demotion to the status of nonresident pupil.
The demotion only lasted a month before Nijinsky was pardoned and invited to become a resident student of the School again.
