History of New York City (1898–1945)

The history of New York City (1898-1945) began with the formation of the consolidated city of the five boroughs in 1898. A series of new transportation links, most notably the New York City Subway, first opened 1904, helped bind the new city together. The height of European immigration brought social upheaval. Later, in the 1920s, the city saw the influx of African Americans as part of the Great Migration from the American South, and the Harlem Renaissance, part of a larger boom time in the Prohibition era that saw dueling skyscrapers in the skyline. The city suffered during the Great Depression, which saw the election of Republican reformer Fiorello La Guardia and the fall of Tammany Hall after eighty years of political dominance. The city also played a significant part in World War II.

Ragtime Era

The modern city of New York — the five boroughs — was created in 1898, with the consolidation of the cities of New York (then Manhattan and the Bronx) and Brooklyn with the then largely rural areas of Queens and Staten Island.

The municipal consolidation would also precipitate greater physical connections between the boroughs. The building of the New York City Subway, as the separate Interborough Rapid Transit Company and Brooklyn-Manhattan Transit Corporation systems, and the later Independent Subway System, and the opening of the first IRT line in 1904 marked the beginning of what became a force for population spread and development. The Williamsburg Bridge 1903 and the Manhattan Bridge 1909 further connected Manhattan to the rapidly expanding bedroom community in Brooklyn. The world-famous Grand Central Terminal opened as the world's largest train station on February 1, 1913, replacing an earlier terminal on the site. It was preceded by Pennsylvania Station, several blocks to the south.

These years also saw the peak of European immigration and the shifting of that immigration from Western Europe to Southern and Eastern Europe. On June 15, 1904 over 1,000 people, mostly German immigrants, were killed when the steamship General Slocum caught fire and burned in the East River, marking the beginning of the end of the community in Little Germany. The German community was replaced by growing numbers of poorer immigrants on the Lower East Side. On March 25, 1911 the Triangle Shirtwaist Factory fire in Greenwich Village took the lives of 145 mostly Italian and Jewish female garment workers, which would eventually lead to great advancements in the city's fire department, building codes, and workplace regulations. It also spurred the growth of the International Ladies' Garment Workers' Union, and took place in the context of broader unionist and leftist movements and the popularity of figures like Emma Goldman.

In 1905, the government of the United Kingdom under Marquess Salisbury was forced to borrow a massive loan from the New York Stock Exchange to help finance reconstruction of South Africa following the Second Boer War. This loan demonstrated to the world that New York was about to take over from London as the hub of international finance.

New York City was the main point of embarkation for U.S. troops traveling to Europe during World War I. There was much fear of German sabotage, highlighted by the Black Tom Explosion in 1916.

Jazz Age

Immigrant families continued establishing themselves, and more started moving into the neighborhoods outside Manhattan; in a sign of municipal maturation, the 1920 census showed Brooklyn for the first time overtaking Manhattan as the most populous borough. But the great period of European immigration which had only just passed its peak was halted abruptly by the Immigration Act of 1924 which severely limited further immigrants from Southern and Eastern Europe. This period instead saw a major domestic movement to the city, as the Great Migration of African Americans from the South resulted in a flowering of African American culture in the Harlem Renaissance.

Fun-loving Tammany mayor Jimmy Walker for most of his term presided over a period of prosperity for the city, with the proliferation of the speakeasy during Prohibition.

On September 16, 1920 radicals in the city perpetrated the Wall Street bombing, a terrorist attack outside the headquarters of the House of Morgan, killing dozens of people and injuring hundreds. The bombing, timed for the busy lunch hour, was unusual for targeting larger numbers of ordinary people. It was the most deadly act of politically-motivated terror on American soil until the Oklahoma City bombing in 1995. Officials blamed anarchist and communist elements, fueling the ongoing Palmer raids. Shortly before the bomb went off, a warning note was placed in a mailbox at the corner of Cedar Street and Broadway. The warning read: "Remember we will not tolerate any longer. Free the political prisoners or it will be sure death for all of you. American Anarchists Fighters." After twenty years investigating the matter the FBI rendered the file inactive in 1940 without ever finding the perpetrators.

Tin Pan Alley developed toward Broadway, and the first modern musical, Jerome Kern's "Show Boat" opened in 1927 as the theater district moved north of 42nd Street.

New York City became known for its daring and impressive architecture, most notably the skyscrapers which transformed the skyline, with the race to the sky culminating in the dueling spires of the Art Deco icon the Chrysler Building and the Empire State Building of the late 1920s, which were not topped off until a period when their soaring heights seemed rather overoptimistic. The city grew outward, too, replacing most of the farmland of eastern Brooklyn and eastern Bronx, and much of Queens, with residential development.

In the 1924 presidential election, New York City voted for Calvin Coolidge, the last time it ever was won by a Republican presidential candidate.

Great Depression and WWII

The Great Depression, which was to affect the rest of the world, began with the Stock Market Crash of 1929. The Depression was both a time of unemployment and poverty, and a period of increased government involvement in the economy.

With the economic decline, criticism of Mayor Walker grew, from Patrick Cardinal Hayes and then from New York Governor Franklin D. Roosevelt, who broke with Walker and Tammany. Mayor Walker came under increasing pressure in the midst of FDR's 1932 Presidential campaign, and resigned to relocate to Europe fleeing potential criminal charges.

When FDR was elected, the Hooverville shacks named after his predecessor dotted city parks, but the city would benefit from the New Deal and the Works Progress Administration, which among other things financed much public art locally. The recently completed Empire State Building would be known as the "Empty State Building" for many years because it could not attract sufficient tenants in the bleak business climate.

In 1934, Republican reformer Fiorello La Guardia was elected mayor. La Guardia, sometimes considered New York's greatest mayor, was of both Italian and Jewish descent and acted as an exuberant populist with a multi-ethnic sensibility. La Guardia's term also saw the rise of the long-careered planner Robert Moses, bridges, parks and parkways coordinator, and great proponent of automobile-centered modernism, whose legacy of massive construction projects is controversial today. The last large expansion of the subway system and municipal ownership of the previously privately owned subway companies gave the system its final shape.

New York, long a great American city with many immigrants, became a culturally international city with the influx of intellectual, musical and artistic European refugees that started in the late 1930s.

The 1939 New York World's Fair, marking the 150th anniversary of George Washington's inauguration in Federal Hall, was a high point of technological optimism, meant to mark the end of the Depression. After the start of World War II, though, the theme was changed from "Building the World of Tomorrow" to "For Peace and Freedom", and a shadow affected the proceedings.

The city was a significantly affected by the military conflict; shipping was hurt by the U-boats, many windows were blacked out for fear of German bombing that never materialized, and the Brooklyn Navy Yard again set to increased production of warships.
