10 Important Events in the History of Latin America

10 Important Events in the History of Latin America Latin America has been always shaped by events as much as by people and leaders. In the long and turbulent history of the region, there were wars, assassinations, conquests, rebellions, crackdowns, and massacres. Which was the most important? These ten were selected based on international importance and effect on the population. It is impossible to rank them on importance, so they are listed in chronological order. 1. Papal Bull Inter Caetera and the Treaty of Tordesillas (1493–1494) Many people do not know that when Christopher Columbus discovered the Americas, they already legally belonged to Portugal. According to previous papal bulls of the 15th century, Portugal held claim to any and all undiscovered lands west of a certain longitude. After Columbus return, both Spain and Portugal laid claims to the new lands, forcing the pope to sort things out. Pope Alexander VI issued the bull Inter Caetera in 1493, declaring that Spain owned all new lands west of a line 100 leagues (about 300 miles) from the Cape Verde Islands. Portugal, not pleased with the verdict, pressed the issue and the two nations ratified the Treaty of Tordesillas in 1494, which established the line at 370 leagues from the islands. This treaty essentially ceded Brazil to the Portuguese while keeping the rest of the New World for Spain, therefore laying the framework for the modern demographics of Latin America. 2. The Conquest of the Aztec and Inca Empires (1519–1533) After the New World was discovered, Spain soon realized that it was an incredibly valuable resource that should be pacified and colonized. Only two things stood in their way: the mighty Empires of the Aztecs in Mexico and the Incas in Peru, who would have to be defeated in order to establish rule over the newly-discovered lands. Ruthless conquistadores under the command of Hernn Cortà ©s in Mexico and Francisco Pizarro in Peru accomplished just that, paving the way for centuries of Spanish rule and enslavement and marginalization of New World natives. 3.  Independence from Spain and Portugal (1806–1898) Using the Napoleonic invasion of Spain as an excuse, most of Latin America declared independence from Spain in 1810. By 1825, Mexico, Central  America, and South America were free, soon to be followed by Brazil. Spanish rule in the Americas ended in 1898 when they lost their final colonies to the United States following the Spanish-American War. With Spain and Portugal out of the picture, the young American republics were free to find their own way, a process that was always difficult and often bloody. 4.  The Mexican-American War (1846–1848) Still smarting from the loss of Texas a decade before, Mexico went to war with the United States in 1846 after a series of skirmishes on the border. The Americans invaded Mexico on two fronts and captured Mexico City in May of 1848. As devastating as the war was for Mexico, the peace was worse. The Treaty of Guadalupe Hidalgo ceded California, Nevada, Utah, and parts of Colorado, Arizona, New Mexico, and Wyoming to the United States in exchange for $15 million and forgiveness of about $3 million more in debts. 5. The War of the Triple Alliance (1864–1870) The most devastating war ever fought in South America, the War of the Triple Alliance pitted Argentina, Uruguay, and Brazil against Paraguay. When Uruguay was attacked by Brazil and Argentina in late 1864, Paraguay came to its aid and attacked Brazil. Ironically, Uruguay, then under a different president, switched sides and fought against its former ally. By the time the war was over, hundreds of thousands had died and Paraguay was in ruins. It would take decades for the nation to recover. 6. The War of the Pacific (1879–1884) In 1879, Chile and Bolivia went to war after spending decades bickering over a border dispute. Peru, which had a military alliance with Bolivia, was drawn into the war as well. After a series of major battles at sea and on land, the Chileans were victorious. By 1881 the Chilean army had captured Lima and by 1884 Bolivia signed a truce. As a result of the war, Chile gained the disputed coastal province once and for all, leaving Bolivia landlocked, and also gained the province of Arica from Peru. The Peruvian and Bolivian nations were devastated, needing years to recover. 7.  The Construction of the Panama Canal (1881–1893, 1904–1914) The completion of the  Panama Canal  by Americans in 1914 marked the end of a remarkable and ambitious feat of engineering. The results have been felt ever since, as the canal has drastically changed worldwide shipping. Less known are the political consequences of the canal, including the  secession  of Panama from Colombia (with the encouragement of the United States) and the profound effect the canal has had on the internal reality of Panama ever since. 8.  The Mexican Revolution (1911–1920) A revolution of impoverished peasants against an entrenched wealthy class, the Mexican Revolution shook the world and forever altered the trajectory of Mexican politics. It was a bloody war, which included horrific battles,  massacres, and assassinations. The  Mexican Revolution  officially ended in 1920 when Alvaro Obregà ³n became the last general standing after years of conflict, although the fighting continued for another decade. As a result of the revolution, land reform finally took place in Mexico, and the PRI (Institutional Revolutionary Party), the political party that rose from the rebellion, stayed in power until the 1990s. 9.  The Cuban Revolution  (1953–1959) When  Fidel Castro, his brother  Raà ºl  and a ragged band of followers  attacked the barracks at Moncada  in 1953, they may not have known they were taking the first step to one of the most significant revolutions of all time. With the promise of economic equality for all, the rebellion grew until 1959, when Cuban President  Fulgencio Batista  fled the country and victorious rebels filled the streets of Havana. Castro established a communist regime, building close ties  with  the Soviet Union, and stubbornly defied every attempt the  United States  could think of to remove him from power. Ever  since  that time, Cuba has either been a festering sore of totalitarianism in an increasingly democratic  world  or a beacon of hope for all anti-imperialists, depending on your point of view. 10. Operation Condor (1975–1983) In the mid-1970s, the governments of the southern cone of  South America- Brazil, Chile, Argentina, Paraguay,  Bolivia, and Uruguay- had several things in common. They were ruled by conservative regimes, either dictators or military juntas, and they had a growing problem with opposition forces and dissidents.  They, therefore,  established Operation Condor, a collaborative effort to round up and kill or otherwise silence their enemies. By the time it ended, thousands were dead or missing and the trust of South Americans in their leaders was forever shattered. Although new facts come out occasionally and some of the worst perpetrators have been brought to justice, there are still many questions about this sinister operation and those behind it.

The Voyager Mission

The Voyager Mission In 1979, two tiny spacecraft were launched on one-way missions of planetary discovery. They were the twin  Voyager spacecraft, predecessors to the  Cassini spacecraft at Saturn, the Juno mission at Jupiter, and the New Horizons mission to Pluto and beyond. They were preceded in gas giant space by the Pioneers 10 and 11. The Voyagers, which are still transmitting data back to Earth as they leave the solar system, each  carry an array of cameras and instruments designed to  record magnetic, atmospheric, and other data about the planets and their moons, and to send images and data for further study back on Earth.   Voyagers Trips Voyager 1 is speeding along at about 57,600 kph (35,790 mph), which is  fast enough to travel from Earth to the Sun three and a half times in one year. Voyager 2 is   Both spacecraft  carry a gold record greeting to the universe  containing sounds and images selected to portray the diversity of life and culture on Earth. The two-spacecraft Voyager missions were designed to replace original plans for a Grand Tour of the planets that would have used four complex spacecraft to explore the five outer planets during the late 1970s. NASA canceled the plan in 1972 and instead proposed to send two spacecraft to Jupiter and Saturn in 1977. They were  designed to explore the two gas giants in more detail than the two Pioneers (Pioneers 10 and 11) that preceded them. The Voyager Design and Trajectory The original design of the two spacecraft was based on that of the older Mariners (such as Mariner 4, which went to Mars). Power was provided by three plutonium oxide radioisotope thermoelectric generators (RTGs) mounted at the end of a boom. Voyager 1 was launched after Voyager 2, but because of a faster route, it exited the Asteroid Belt earlier than its twin. Both spacecraft got gravitational assists at each planet they passed, which aligned them for their next targets.   Voyager 1 began its Jovian imaging mission in April 1978 at a range of 265 million kilometers from the planet; images sent back by January the following year indicated that Jupiters atmosphere was more turbulent than during the Pioneer flybys in 1973 and 1974. Voyager Studies Jupiters Moons On February 10, 1979, the spacecraft crossed into the Jovian moon system, and in early March, it had already discovered a thin (less than 30 kilometers thick) ring circling Jupiter. Flying past Amalthea, Io, Europa, Ganymede, and Callisto (in that order) on March 5th, Voyager 1 returned spectacular photos of these worlds. The more interesting find was on Io, where images showed a bizarre yellow, orange and brown world with a least eight active volcanoes spewing material into space, making it one of the most (if not the most) geologically active planetary bodies in the solar system. The spacecraft also discovered two new moons, Thebe and Metis. Voyager 1s closest encounter with Jupiter was at 12:05 UT on March 5, 1979, at a range of 280,000 kilometers. On to Saturn Following the Jupiter encounter, Voyager 1 completed a single course correction on April 89 1979, in preparation for its rendezvous with Saturn. The second correction on October 10, 1979, ensured that the spacecraft would not hit Saturns moon Titan. Its flyby of the Saturn system in November 1979 was as spectacular as its previous encounter. Exploring Saturns Icy Moons Voyager 1 found five new moons and a ring system consisting of thousands of bands, discovered a new ring (the G  Ring), and found shepherding satellites on either side of the F-ring satellites that keep the rings well defined. During its flyby, the spacecraft photographed Saturns moons Titan, Mimas, Enceladus, Tethys, Dione, and Rhea. Based on incoming data, all the moons appeared to be largely composed of water ice. Perhaps the most interesting target was Titan, which Voyager 1 passed at 05:41 UT on  November 12th at a range of 4,000 kilometers. Images showed a thick atmosphere that completely hid the surface. The spacecraft found that the moons atmosphere was composed of 90 percent nitrogen. Pressure and temperature at the surface were 1.6 atmospheres and -180 ° C, respectively. Voyager 1s closest approach to Saturn was at 23:45 UT on November 12,  1980, at a range of 124,000 kilometers. Voyager 2 followed up with visits to Jupiter in 1979, Saturn in 1981, Uranus in 1986, and Neptune in 1986. Like its sister ship, it investigated planetary atmospheres, magnetospheres, gravitational fields, and climates, and discovered fascinating facts about the moons of all the planets. Voyager 2 also was the first to visit all four gas giant planets. Outward Bound Because of the specific requirements for  the Titan flyby, the spacecraft was not directed to Uranus and Neptune. Instead,  following the encounter with Saturn, Voyager 1 headed on a trajectory out of the solar system at a speed of 3.5 AU per year. It is on a course 35 ° out of the ecliptic plane to the north, in the general direction of the Suns motion relative to nearby stars. It is now in interstellar space, having passed through the  heliopause boundary, the outer limit of the Suns magnetic field, and the outward flow of the solar wind. Its the first spacecraft from Earth to travel into interstellar space. On February 17, 1998, Voyager 1  became the most distant human-made object in existence when it surpassed Pioneer 10s range from Earth. In mid-2016, the  Voyager 1  was more than  20 billion kilometers from Earth (135 times the Sun-Earth distance) and continuing to move away, while maintaining a tenuous radio link with Earth. Its power supply should last through 2025, allowing the transmitter to keep sending back information about the interstellar environment. Voyager 2 is on a trajectory headed out toward the star Ross 248, which it will encounter in about 40,000 years, and pass by Sirius in just under 300,000 years. It will keep transmitting as long as it has power, which may also be until the year 2025.   Edited and updated by Carolyn Collins Petersen.
