NYC Police riot of 1857

Known at the time as the Great Police Riot, was a conflict which occurred in front of New York City Hall between the recently-dissolved New York Municipal Police and the newly-formed Metropolitan Police. Arising over New York City Mayor Fernando Wood's appointment of Charles Devlin over Daniel Conover for the position of city street commissioner, amid rumors that Devlin purchased the office for $50,000 from Wood, Municipal police battled Metropolitan officers attempting to arrest Mayor Wood.Two arrest warrants had been issued against the mayor following an altercation between him and Conover when arriving at City Hall to assume his office. The situation was resolved only with the intervention of the New York State Militia under Major General Charles W. Sandford.
