A Tug-of-War contest was first held in 1921.

The class of '24, taking advantage of the student council's decision to institute a Tug-of-War Rush, has challenged the Sophomore class and, needless to say, 1923 has eagerly accepted the challenge.

The day of the battle will depend upon the weather, though it will probably be staged during the last days of April. The tract of land on Fifteenth St., facing the Hunt and White dormitories, will be the scene of action.

The tussle will last for seven minutes, during which time no man will be allowed to let go of the rope on which a fire hose, loaned to the Institute by the city, will play. There will be a definite number of men representing each class, and Grand Marshal Thompson will notify the men of the time elapsed by signaling after five and seven minutes respectively. It is believed that this will soon become the most popular Rush on the Hill. [The Polytechnic April 14, 1921]

The contest eventually became a part of Freshmen Week and was often held the same day as the Grease Rush. Tug-of-War, along with other Freshmen Week activities, was discontinued in 1959.
