In a legislative act of February 12, 1796, New York State was divided into seven districts, each with its own Assistant Attorney General. Queens County was part of the First District, which also included Kings, Richmond, Suffolk, and Westchester counties. (At that time, Queens County included much of present-day Nassau County, and Westchester County included present-day Bronx County.) In 1801, the office of Assistant Attorney General was renamed District Attorney. At the same time, New York County was added to the First District. Westchester County was separated from the First District in 1813, and New York County was separated in 1815. In 1818, all 13 districts were broken up, and each county in the State of New York became a separate district. Until 1822, the district attorney was appointed by the
Council of Appointment, and held the office "during the Council's pleasure", meaning that there was no defined term of office. Under the provisions of the
State Constitution of 1821, the D.A. was appointed to a three-year term by the County Court. Under the provisions of the
State Constitution of 1846, the office became elective by popular ballot. The term was three years, beginning on January 1 and ending on December 31. In case of a vacancy, the
Governor of New York filled the vacancy temporarily until a successor was elected, always to a full term, at the next annual election. One year after the 1898 Consolidation of
New York City, Nassau County was separated from Queens County. In case of a vacancy, a DA is appointed by the Governor to fill the office temporarily. A new DA is then elected at the next annual election in November, always to a full term. From 1847 to 1942, the term length was three years. In November 1942, a DA was elected to a one-year term. From the election of November 1943, the DA has been elected to a four-year term. ==List of district attorneys==
