1523. In 1717 it was included in the Viceroyalty of New Granada
. Venezuelan Creoles led by Francisco de Miranda
and Simón Bolívar
spearheaded the South American independence movement, and, though Venezuelans had declared independence from Spain as early as 1797, it was not assured until the last royalist forces surrendered in 1823. Military dictators generally ruled the country from 1830 until the overthrow of Marcos Pérez Jiménez
in 1958. A new constitution adopted in 1961 marked the beginning of democracy. As a founding member of OPEC (Organization of Petroleum Exporting Countries

The government of Hugo Chávez promulgated a new constitution in 1999, the year in which a devastating rainstorm killed thousands in and around Caracasone of the deadliest events in Venezuelan history. Despite an increase in oil prices in the early 21st century, the country experienced great political turmoil.
