Exploring The Length Of Paraguay-Bolivia Border

Paraguay and Bolivia share a border that runs for 466 miles (750 kilometres) along the northwestern edge of Paraguay, separating the Alto Paraguay department from Bolivia. The border, which is the shortest of Paraguay's three borders, moves north from the boundary with Argentina and later turns eastward toward the boundary with Brazil. This region of Paraguay is known as Alto Chaco, where the plains begin to develop hilly terrain. The border between these two countries also holds the northernmost point in Paraguay, known as the Hito VII Fortin Coronel Sanchez pillar.

The boundary between Paraguay and Bolivia is in the Gran Chaco region

The Chaco Boreal, or Northern Chaco, is the area north of the Pilcomayo River up to the Brazilian Pantanal, inside Paraguayan territory and sharing some area with Bolivia. The Paraguayan Chaco is subdivided into two parts: the Alto Chaco (Upper Chaco) or Chaco Seco (Dry Chaco), which is the western three-quarters of the region, bordering Bolivia; and the Bajo Chaco (Lower Chaco) or Chaco Húmedo (Humid Chaco), which borders the Paraguay River. The Chaco Boreal may also be divided into two: the Alto Chaco, a very dry area with sparse vegetation; and the Bajo Chaco, which has less arid conditions and higher rainfall, resulting in a swampy plain with palm trees, quebracho trees, and tropical high-grass areas.

The Gran Chaco has been a disputed territory since 1810 and was the site of the Gran Chaco War between Paraguay and Bolivia from 1932 to 1935. The war was fought over control of the northern part of the Gran Chaco, which was thought to be rich in oil. The peace treaty that ended the war granted two-thirds of the disputed territories to Paraguay, including three-quarters of the Chaco Boreal.

The Chaco War was fought between Bolivia and Paraguay over control of the northern part of the Gran Chaco region

The boundary between Bolivia and Paraguay, which extends through the low hills of the Chaco region, was defined in 1938. The Chaco War, fought between Bolivia and Paraguay from 1932 to 1935, was a conflict over control of the northern part of the Gran Chaco region, also known as the Chaco Boreal. This region, covering an area of about 100,000 square miles, is a wilderness of lowland swamps and jungles, with the Paraguay River running through it.

The Chaco War was the bloodiest interstate military conflict fought in South America in the 20th century, with around 100,000 casualties. It was fought between two of the poorest countries in South America, both of which had lost territory to neighbours in 19th-century wars. The war was sparked by a long-standing territorial dispute and the discovery of oil deposits in the eastern Andes range. Both countries were landlocked and sought access to the Atlantic Ocean, with control of the Paraguay River being a key strategic objective.

The conflict began in 1928 with a series of clashes and border skirmishes. Bolivia, with a larger and better-equipped army, initially seemed to have the upper hand. However, Paraguay had the advantage of geographical familiarity, with the Paraguayan army composed mainly of European-Guaraní mestizos, who were better suited to the lowland conditions. The Paraguayan army also employed innovative tactics, including rapid marches and flanking manoeuvres, which gave them the advantage over Bolivia's more conventional strategy.

The war consisted of three Paraguayan offensives, with the Paraguayan army successfully capturing and holding key forts and outposts. Despite attempts at mediation and a brief armistice, the conflict escalated, with both sides importing vast quantities of arms and supplies. The Paraguayan army ultimately gained control of most of the disputed zone, and a peace treaty was signed in 1938, granting Paraguay two-thirds of the disputed territories. The war had a devastating impact on both countries, causing economic collapse and leading to significant political and social changes.

The war was also referred to as La Guerra de la Sed (The War of Thirst) because it was fought in the semi-arid Chaco

The boundary between Paraguay and Bolivia is approximately 750 km long. This boundary runs through the low hills of the semi-arid Gran Chaco region, which is divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian state of Mato Grosso do Sul. The name Chaco comes from the Quechua word "chaqu", meaning "hunting land", likely due to the region's rich variety of animal life.

The Chaco region was the site of the bloodiest interstate military conflict in 20th-century South America, known as the Chaco War or La Guerra del Chaco. This war was fought between Bolivia and Paraguay from 1932 to 1935 over control of the northern part of the Gran Chaco, believed to be rich in oil. The conflict resulted in significant losses for both sides, with Bolivia losing between 56,000 and 65,000 people and Paraguay losing about 36,000.

The Paraguayan forces gained an advantage due to their innovative fighting style, centred on rapid marches and flanking manoeuvres, while the Bolivian strategy was more conventional. Additionally, the Paraguayan army utilised their knowledge of the local terrain and the ability to live off the land, which proved valuable in conducting military campaigns. The Paraguayan army also had the benefit of a rail network running to the Chaco, facilitating the transportation of troops and supplies to the front lines.

The Chaco War concluded with a ceasefire in 1935, followed by a peace treaty signed in Buenos Aires in 1938. The treaty granted Paraguay control over two-thirds of the disputed territories, with Bolivia obtaining a corridor to the Paraguay River and navigation rights.

The Paraguayan War was fought between Paraguay and the Triple Alliance of Argentina, the Empire of Brazil, and Uruguay

The boundary between Paraguay and Bolivia is defined by the low hills of the Chaco region and extends from the confluence of the Apa River and Paraguay River northward along the course of the Paraguay River to the border with Bolivia. The length of this boundary is not readily available.

Paraguay, led by President Francisco Solano López, took the initiative during the first phase of the war, invading the Brazilian provinces of Mato Grosso and Rio Grande do Sul and the Argentine Corrientes Province. The Paraguayan forces were well-equipped, with 60,000 trained men, 400 cannons, and a naval squadron. However, they faced logistical challenges and were outnumbered by the combined forces of the Triple Alliance.

The Allied counterattack began in 1865, with the invasion of Paraguay in April 1866. The Battle of Tuyutí, one of the bloodiest battles in Latin American history, resulted in heavy losses for both sides. Despite some victories, the Paraguayan forces were eventually overwhelmed, and López was forced to retreat.

The war had devastating consequences for Paraguay, with massive casualties and the loss of disputed territories to Argentina and Brazil. The country also suffered economic ruin and was occupied by Brazilian and Argentine troops until 1876. The war helped the Brazilian Empire reach its peak of power and influence in South America and contributed to the end of slavery in Brazil.

The Chaco Boreal is a wasteland of some 100,000 square miles west of the Paraguay River

The Chaco Boreal is a semi-arid lowland region of around 100,000 square miles in South America, west of the Paraguay River. It is part of the larger Gran Chaco, a lowland alluvial plain that spans Argentina, Bolivia, and Paraguay. The Chaco Boreal is characterised by its flat land, deciduous scrub woodlands, and forests of spiny, thorny trees. The region has a semi-arid to semi-humid climate, with rainfall between 550 and 1,300 mm per year.

Historically, the Chaco Boreal has been a disputed territory between Bolivia and Paraguay, with both countries claiming ownership of the land. This dispute culminated in the Chaco War, which was fought between 1932 and 1935. The war centred around control of the northern part of the Gran Chaco, known as Chaco Boreal in Spanish, which was thought to be rich in oil. Bolivia sought access to the Paraguay River for shipping oil, while Paraguay aimed to protect its economic viability. The war resulted in significant casualties for both countries, with Paraguay gaining control of most of the disputed zone.

The peace treaties that ended the Chaco War granted two-thirds of the disputed territories, including most of the Chaco Boreal, to Paraguay. This outcome had a significant impact on the region's political and economic landscape. Bolivia, which had already lost its Pacific coast, became landlocked once again. In contrast, Paraguay secured access to the Atlantic Ocean via the Paraguay River.

Today, the Chaco Boreal remains relatively underdeveloped, with a lack of infrastructure and basic services. However, it is an important source of natural resources, including timber, tannin, and oil. Efforts have been made to encourage access and development in the region, such as the construction of highways and roads.
