improve infrastructure. Another crucial event during Pando's presidency was the arrival of the first imported in Bolivia, brought to the country by adventurer Arthur Posnansky. Internationally, Pando fought the so-called Acre War with Brazil. The region of Acre, located in the north and adjacent to the border with Brazil, had been invaded by Brazilian settlers and rubber tappers in the midst of a rubber boom. The Bolivian government, attempting to assert its influence in that region, founded Puerto Alonso in 1899 and established taxes on rubber tappers. But the rubber tappers rebelled and started a secessionist movement called the First Revolution of Acre, which the Bolivian government was able to crush. The second phase of this war, called the Second Acrean Revolution, occurred in 1902; this time, the Acreans asked to be annexed into Brazil. The Bolivians suffered setbacks at the hands of the Acrean revolutionaries, so Pando personally marched to Acre at the head of an army. This motivated the intervention of Brazil, which considered the area in dispute to be theirs and decided to send its army in support of the Acreans. This disparate situation forced the Bolivians to enter negotiations. Pando signed the Treaty of Petrópolis with Brazil by which Bolivia ceded territory in the north in exchange for significant financial compensation of two million pounds sterling. Shortly after returning to La Paz, at the end of his term, Pando handed over power to Ismael Montes, who succeeded him as leader of the Liberal Party. Later life and death Pando was delegate in the territories of the North and Commissioner of Limits with Brazil. He was appointed Brigadier General in the Army of Peru in 1911. Having left the Liberal party, he broke with Ismael Montes and, in 1915, he became the founder of the Republican Party. Retired, Pando was found dead in a ravine near El Kenko (now El Alto) on June 17, 1917. Many believed it was a political crime, perpetrated at the instigation of the Liberal Party. The murder was attributed to Alfredo Jáuregui, Juan Jáuregui, Néstor Villegas and Simón Choque. In 1927, Alfredo Jáuregui, the youngest of the brothers, was shot as a result of his alleged involvement in the crime against Pando. Modern investigations, however, maintain that Pando's death was due to natural causes, when he suffered a stroke while he was going from his farm in Catavi to the city of
