The first mosque in the United States built as a gathering place for Muslims was located in Ross, North Dakota, and was built in 1929. It was pre-dated, however, by a mosque and mission intended to serve the entire New York City community in 1893.
The 1929 mosque no longer survives, though as of 2015, one built only five years later in Cedar Rapids, Iowa, does. Although Islam has only risen to prominence in the United States since the latter half of the 20th century, documentation of Muslims in North America can be traced as back as the 1600s. Many of those individuals were slaves brought on ships from Africa.
