Slavery in Venezuela was abolished in 1854. Much of Venezuela's 19th-century history was characterized by political turmoil and dictatorial rule, including the Independence leader José Antonio Páez, who gained the presidency three times and served a total of 11 years between 1830 and 1863. This culminated in the Federal War (1859–1863), a civil war in which hundreds of thousands died in a country with a population of not much more than a million people. In the latter half of the century, Antonio Guzmán Blanco, another ''caudillo'', served a total of 13 years between 1870 and 1887, with three other presidents interspersed.
