New York City started as a 1,000-feet-thick sheet of ice about 20,500 years ago. The glacier, which formed the area's bedrock, carved out the city's topography we know today.

During the precolonial era (before the 16th century), bands of the Native American tribe Lenape — the original, native New Yorkers — inhabited the area, which they named Lenapehoking. They made use of its flourishing waterways for fishing, hunting trips, and trade.
In 1624, the Dutch decided to colonize the area permanently. A year later, construction started in present-day Manhattan, which they then called New Amsterdam.
Dutch colonial Director-General Peter Minuit purchased the land from the Lenape for 60 guilders (the Dutch currency at the time) — which would be about $1,000 in today's money.

To attract settlers, the Dutch started a rewards system in 1628. For every 50 colonists that wealthy Dutchmen brought to the island, they would be awarded swaths of land, political autonomy, and the rights to participate in fur trade. This program saw little success.

Many shots were fired during the 1776 Battle of Brooklyn — the largest battle in the American Revolution. British forces stormed upon Brooklyn and Long Island, hoping to capture NYC and the Hudson River from George Washington's army. The Brits won but left at the end of the war.
In 1785, New York City became to first capital under the Constitution of the United States. By 1790, New York had surpassed Philadelphia as the largest US city.
Between 1870 and 1915, New York's population tripled — skyrocketing from 1.5 million to 5 million residents.
To support all those people, the city built up its infrastructure. The Manhattan Bridge, which over 70,300 New Yorkers travel over daily today, opened in 1909 ...
Over a century later, approximately 8.5 million people live in NYC's five boroughs.
