The current officeholder, the 110th in the sequence of regular mayors, is Eric Adams, a member of the Democratic Party.
The 1898 consolidation created the city as it is today with five boroughs: Queens, Brooklyn, Manhattan, Staten Island and the Bronx.
The longest-serving mayors have been Fiorello H. La Guardia (1934–1945), Robert F. Wagner Jr. (1954–1965), Ed Koch (1978–1989) and Michael Bloomberg (2002–2013), each of whom was in office for twelve years (three successive four-year terms).
(When the same man served more than one continuous term, his name is lightly shaded purely for clarity, but the tints have no other significance.)
Since then, mayors have had to be elected with the support of all five boroughs: Queens, Brooklyn, Manhattan, Staten Island, and the Bronx.
The 1897 Charter of the consolidated City stipulated that the mayor was to be elected for a single four-year term.
(Mayors Fiorello La Guardia, Robert F. Wagner Jr. and Ed Koch were later able to serve for twelve years each.)
In 2008, the New York City Council voted to change the two-term limit to three terms (without submitting the issue to the voters).
