Question: what riot in May 10,1849, has the same name as a theatre in Manhattan, New York City?
Context: Catherine Butterfield (born February 5, 1958 in Manhattan, New York City, New York) is an American playwright, TV/film writer and actress.  Her play "Joined at the Head" was performed at the Manhattan Theatre Club in 1992 and won the Robert L. Stevens/Kennedy Center award for excellence, as well as being published in "Best Plays of 1992-93" (ISBN  ).  Mel Gussow wrote, "In this, her first full-length play to be presented in New York, Butterfield is revealed as a playwright with a refreshing talent for probing the reality of relationships.  In a manner related to that of Tom Stoppard and John Guare, the work deals enticingly with truth and fiction... a vibrant reflection on life and art."  (New York Times, November 19, 1992, "When an Old Friendship Is More Than It Seems".)  Subsequent award-winning plays include "Life in the Trees" (Davie award—Best new play in regional theatre) and "The Sleeper" (2004 Kaufman and Hart Prize for new American comedy.) The Astor Place Riot occurred on May 10, 1849, at the now-demolished Astor Opera House in Manhattan, New York City and left at least 25 dead and more than 120 injured.  It was the deadliest to that date of a number of civic disturbances in New York City which generally pitted immigrants and nativists against each other, or together against the upper classes who controlled the city's police and the state militia. The Orange Riots took place in Manhattan, New York City in 1870 and 1871, and they involved violent conflict between Irish Protestants, called "Orangemen", and Irish Catholics, along with the New York City Police Department and the New York State National Guard.  The riot caused the deaths of over 60 civilians – mostly Irish laborers – and three Guardsmen. The recorded history of Rockland County, New York begins on February 23, 1798, when the county was formed as an administrative division of the state of New York.  It is located 12 mi north-northwest of New York City, and is part of the New York Metropolitan Area.  The county seat is the hamlet of New City.  The name comes from "rocky land", an early description of the area given by settlers.  Rockland is New York's southernmost county west of the Hudson River.  It is suburban in nature, with a considerable amount of scenic designated parkland.  Rockland County does not border any of the New York City boroughs, but is only 9.5 mi north of Manhattan at the counties' (New York and Rockland) two respective closest points (Palisades, New York, in Rockland and Inwood Park in Manhattan) The Hard Hat Riot occurred on May 8, 1970, in New York City.  It started around noon when about 200 construction workers mobilized by the New York State AFL-CIO attacked some 1,000 college and high school students and others who were protesting the May 4 Kent State shootings, the Vietnam War, and the April 30 announcement by President Richard Nixon of the U.S. invasion of Cambodia.  The Hard Hat Riot, breaking out first near the intersection of Wall Street and Broad Street in Lower Manhattan, soon spilled into New York City Hall, and lasted approximately two hours.  More than 70 people, including four policemen, were injured on what became known as "Bloody Friday".  Six people were arrested. The Astor Place Theatre is an off-Broadway house located at 434 Lafayette Street in the NoHo section of Manhattan.  The theater is located in the historic Colonnade Row, originally constructed in 1831 as a series of nine connected buildings, of which only four remain.  Though it bears the same name, it was not the site of the Astor Place Riot of 1849. 421-a tax abatement is a property tax abatement in the state of New York that is given to real estate developers for building new multi-family residential housing buildings.  The program gets its name from being from section 421-a in the New York Real Property Tax Law.  The 421-a program began in 1971, and has since included provisions in it to mandate the creation of affordable housing units in order to qualify for the program.  Under the original program, areas in which developers qualified for the tax break included all of Manhattan and portions of the rest of New York City.  The original program lapsed in January 2016 after disagreements between the state government and the New York City government, but a deal was made in November 2016 between unions, developers, and Governor Andrew Cuomo to bring it back, pending the approval of the New York State Legislature.  In the April 2017 budget negotiations, the program was officially renewed, with the official new program name being "Affordable New York".  The program is administered by the New York City Department of Housing Preservation and Development (HPD).  Under the program, the city government stands to lose billions of dollars in foregone property tax revenue, making this program controversial. The Coroner of New York City issued death certificates and performed autopsies and inquests for New York County, New York for all homicides, suicides and accidental deaths and any suspicious deaths.  The office served only Manhattan until 1891 when the city expanded.  After the 1891 consolidation of New York City the office handled the outer boroughs, with each outer borough having two coroners.  Coroners are elected at the same time as the Mayor of New York City for a term of four years and there was no requirement that the candidate had to be a physician.  They may be removed from office by the Governor of New York.  If a coroner dies in office, or is fired, or quits, someone is appointed to fill out their term.  The coroners received a salary and also billed the city for services rendered for each autopsy and inquest.  By 1896 the Manhattan coroner was earning $6,000 per year, and in 1897 each inquest was billed at $8.50.  In 1915 a law was passed and the office was to be abolished on January 1, 1918.  It was replaced with the Office of Chief Medical Examiner of the City of New York.  The medical examiner was to be a physician and no longer had the ability to hold inquests, those powers were transferred to the district attorney.  Between 1898 when the city was consolidated and 1915 when the office went from coroner to medical examiner, 65 coroners had served in the position.  Of them, 19 were physicians, 8 were undertakers, 7 were politicians, 6 were real estate agents, 2 were saloon keepers, 2 were plumbers, 1 was a musician, 1 was a dentist, and 1 was a butcher. The Tompkins Square Park Riot occurred on August 6–7, 1988 in New York City's Tompkins Square Park.  Groups of "drug pushers, homeless people and young people known as squatters and punks, had largely taken over the park.  The Alphabet City/East Village neighborhood, in which the park was located, was divided about what, if anything, should be done about it.  The local governing body, Manhattan Community Board 3, recommended, and the New York City Parks Department adopted, a 1 a.m. curfew for the previously 24-hour park, in an attempt to bring it under control.  On July 31, a protest rally against the curfew saw several clashes between protesters and police. The Harlem riot of 1935 took place on March 19 during the Great Depression, in New York City, New York, in the United States.  It has been described as the first "modern" race riot in Harlem, because it was committed primarily against property rather than persons.  Harlem is a northern neighborhood on Manhattan island in New York City whose population at the time was predominately African American.  The rioting did not feature two ethnic groups in conflict.
