Before the 1900s, most Americans had never heard of tacos. But in Mexico, Indigenous peoples had been eating tacos for more than 1,000 years. The earliest taco lovers made corn tortillas by hand and then folded them around bits of meat and beans, ready to be enjoyed.
By the 1900s, taco carts were common in Mexico City, the capital of Mexico. Fried tortillas stuffed with potatoes and salsa gave workers a quick lunch on the go.
Around this time, many Mexican workers began traveling to the United States in search of railroad, mining, or farm jobs. As they traveled north, they brought their tacos with them.
By the 1950s, the children and grandchildren of these first immigrants began adding new flavors to the dish. They experimented with ingredients that were available in U.S. supermarkets, such as ground beef, fresh tomatoes, crunchy lettuce, and shredded cheddar cheese.
Meanwhile, Mexican Americans began opening restaurants throughout the Southwest—and what starred on the menu? Tacos, of course!
