Until the mid-20th century most of Yucatán's contact with the outside world was by sea; trade with the US and Cuba, as well as Europe and other Caribbean islands, was more significant than that with the rest of Mexico. In the 1950s Yucatán was linked to the rest of Mexico by railway, followed by highway in the 1960s, ending the region's comparative isolation. Today Yucatán still demonstrates a unique culture from the rest of Mexico, including its own style of food.
