Mayor of Princeton, New Jersey

Princeton was founded by Europeans in the latter part of the 17th century. Because of a dispute over school taxes, the municipality split into the Borough of Princeton and Princeton Township in 1894, and both became fully independent municipalities. On January 1, 2013, the two consolidated as Princeton under a borough form of government.
