this area is called the Lost World (Mundo Perdido). The Andean valleys are undoubtedly the most impressive of the Venezuelan territory because of the energy of the encasing reliefs, whose summits often dominate the valley bottoms by 3,000 to 3,500 meters of relative altitude. They are also the most picturesque in terms of their style of habitat, forms of land use, handicraft production and all the traditions linked to these activities. these activities Deserts Venezuela has a great diversity of landscapes and climates, including arid and dry areas. The main desert in the country is in the state of Falcon near the city of Coro. It is now a protected park, the Médanos de Coro National Park. The park is the largest of its kind in Venezuela, covering 91 square kilometres. The landscape is dotted with cacti and other xerophytic plants that can survive in humidity-free conditions near the desert. Desert wildlife includes mostly lizards, iguanas and other reptiles. Although less frequent, the desert is home to some foxes, giant anteaters and rabbits. There are also some native bird populations, such as the sparrowhawk, tropical mockingbird, scaly dove and crested quail. Other desert areas in the country include part of the Guajira Desert in the Guajira Municipality in the north of Zulia State and facing the Gulf of Venezuela, the Médanos de Capanaparo in the Santos Luzardo National Park in Apure State, the Medanos de la Isla de Zapara in Zulia State, the so-called Hundición de Yay in the Andrés Eloy Blanco Municipality of Lara State, and the Urumaco Formation also in Falcón State. Government and politics Following the fall of Marcos Pérez Jiménez in 1958, Venezuelan politics were dominated by the Third Way Christian democratic COPEI and the center-left social democratic Democratic Action (AD) parties; this two-party system was formalized by the puntofijismo arrangement.

A collapse in confidence in the existing parties saw the 1998 election of Hugo Chávez, who had led the first of the 1992 coup attempts, and the launch of a "Bolivarian Revolution", beginning with a 1999 Constituent Assembly to write a new Constitution of Venezuela. The opposition's attempts to unseat Chávez included the 2002 Venezuelan coup
