American Urbanization & New York City discusses the history and development of New York City from its origins as the Dutch settlement of New Amsterdam in the 1600s. It details key events like the arrival of the first African slaves in 1626 and the British surrender to the American colonies in 1783 during the Revolutionary War. The document also examines New York City during the Great Depression era of the 1930s, when corrupt mayor Jimmy Walker pocketed relief funds while over 1/3 of the nation was unemployed. His successor Fiorello LaGuardia promised to end corruption and worked to reform the city government.
