The low-slung jungles of the Yucatan Peninsula were first settled more than 2,000 years ago by the Maya. Their advanced civilization and elaborate temples continue to fascinate archaeologists and casual visitors alike. By the time Hernando Cortes began the Spanish conquest of Mexico in 1519, the Mayan culture was already in decline, but the conquistadores accelerated that decline with deadly European diseases and weaponry. Eventually, the northern part of the Yucatan was settled by landowners of Spanish descent who used the Maya as workers.
Despite its scattered agricultural holdings, the area was largely ignored by the rest of Mexico, both during the colonial period and after independence. That was mostly because the region was very isolated. For centuries, the only practical way to get there was by sea: The first rail line wasn't built until 1949. When the Mexican government began scouting sites for a tourist resort in the 1960s, the idea of Cancun was born. After a few years of furious building, the idea became a city. The first resorts opened for business in 1974, and the surrounding region was designated as the state of Quintana Roo at about the same time. In the decades since, Cancun has grown more and more popular and has stimulated a booming tourism business along the Yucatan coast.
Cancun can no longer support new hotels because no more land is available for building. However, new developments with hotels and golf courses are being designed for areas slightly north and south of Cancun.
