Designed to supplement Disneyland, in Anaheim, California, which had opened in 1955, the complex was developed by Walt Disney in the 1960s. "The Florida Project", as it was known, was intended to present a distinct vision with its own diverse set of attractions. Walt Disney's original plans also called for the inclusion of an "Experimental Prototype Community of Tomorrow" (EPCOT), a planned community intended to serve as a test bed for new city-living innovations. Walt Disney died on December 15, 1966, during construction of the complex. Without him spearheading the construction, the company built a resort similar to Disneyland, abandoning the experimental concepts for a planned community. Magic Kingdom was the first theme park to open in the complex, in 1971, followed by Epcot (1982), Disney's Hollywood Studios (1989), and Disney's Animal Kingdom (1998).
