New York State was the site of the deadliest terrorist attack in United States history prior to 9/11. In 1993, a bomb planted in the World Trade Center by Islamic extremists killed six people and injured more than a thousand others.
Westchester County, located in the southeastern part of the state of New York, has a rich history dating back thousands of years. The original inhabitants of the area were Native American tribes, including the Wappinger and Siwanoy, who lived off the bountiful resources of the Hudson River and the region's forests.

European colonization of Westchester began in the early 1600s, when Dutch settlers established trading posts and farms in the area. The Dutch West India Company purchased land from Native American tribes and built settlements along the Hudson River, including present-day Yonkers and Tarrytown. In 1674, Westchester came under English rule as part of the Province of New York, and English towns and cities began to emerge.

During the American Revolution, Westchester County played a crucial role as a strategic location between the British-held city of New York and the Continental Army's headquarters in the Hudson Valley. Several major battles and skirmishes took place in the area, including the Battle of White Plains in 1776. Westchester residents were divided in their loyalties, with some supporting the British Crown and others fighting for American independence.

In the 19th and 20th centuries, Westchester experienced rapid industrialization and suburbanization. The construction of railroads and the opening of the Tappan Zee Bridge in 1955 facilitated the growth of commuter suburbs, attracting residents from New York City. Today, Westchester County is known for its wealthy towns, vibrant arts scene, and scenic landscapes, making it a popular destination for residents and visitors alike.
