Ecuador’s history is as varied as its geography. Pre-Colombian agricultural societies existed for about 15,000 years before the Inca folded the land and its inhabitants into their empire at the end of the 15th century (Quechua, the language of the Incas, is still widely spoken among the indigenous peoples). In 1532, Francisco Pizarro led the campaign to defeat the powerful Inca, and in 1822, Simón Bolívar liberated Ecuador from Spanish reign.
