Mayors, 1890-1948
The Freeholders Charter of 1890 changed the term of office for the Mayor to two years and made the incumbent ineligible for re-election until after the lapse of two years. Elections were held on the first Monday in March. The two-year term was maintained under a new Freeholders' Charter of 1896, but the restriction on re-election was removed. Elections were changed to the Tuesday following the first Monday in March. A charter amendment passed by the voters on March 8, 1910, established non-partisan nominations and elections for all City elective offices. In 1921 the State Legislature established elections on the first Tuesday following the first Monday in May. Two years later, the elections were moved back to the second Tuesday in March.
