The streets of New Orleans, Louisiana, are packed with colorful floats, marching bands, and costumed crowds this month. Each year, more than 1 million people attend an annual festival called Mardi Gras [MAHR-dee grah) there. But this year is extra-special. New Orleans is turning 300!
The city of New Orleans was founded on May 7, 1718, by a French explorer. At the time, the United States didn’t exist yet. New Orleans became part of New France, an area of North America that France controlled then. In 1776, the U.S. became a country. It bought some of New France—including New Orleans—in 1803 as part of a land deal called the Louisiana Purchase.
