While Cambridge has a storied religious history and has been home to many groups of immigrants, neither Muslims from the United States nor those from other parts of the world were a significant presence in the city until the mid-twentieth century. Muslims are absent from a number of books about the history of the city. This is probably in part because their numbers are smaller than many other religious groups in Cambridge. In the 1950's, there was a small Muslim population at Harvard. A few graduate students who were here from other countries and studying Islamic history founded the Harvard Islamic Society in 1958. In 1958, three Harvard students formed the Harvard Islamic Society, It was the first Muslim organization in Cambridge and one of the first student Muslim organizations in the United States. According to the Harvard Islamic Society’s web site, American-born Muslim students first came to Harvard in the 1970’s.
