The 'Argentine War of Independence' was fought from 1810 to 1818 by Argentine forces under
Manuel Belgrano and
José de San MartÃn against ''realista'' forces loyal to the
Spanish crown. On
July 9,
1816, an assembly met in
San Miguel de Tucumán,
declared full independence with provisions for a
national constitution.
Background
The territory known today as Argentina was part of the Spanish
Viceroyalty of the RÃo de la Plata and its capital city was the Intendency of Buenos Aires. It was ruled by a
viceroy appointed by the Spanish Crown and guarded by the Spanish royal army. The beginning of the conflict was the full prohibition of trading with all countries except for Spain. English, French, and Portuguese ships were banned from the port at Buenos Aires. Despite this legislation, the citizens of Buenos Aires were well known as ''trafficants'' and they would often trade illegally with many foreign merchants. The resistance, organized by the local
criollos during the
British invasions of the RÃo de la Plata while viceroy
Rafael de Sobremonte escaped to hide himself along with the state's treasure, helped to create up a national identity.
On
May 13,
1810, the arrival of a
British frigate in
Montevideo brought news that
Napoleon Bonaparte had invaded Spain, capturing and
overthrowing
King Ferdinand VII, and triggered a brief period of political turmoil. This series of events is known as the
May Revolution as citizens gathered in the
Cabildo (City Hall) and decided to suspend Viceroy
Baltasar Hidalgo de Cisneros from office and to create the First Junta (
Primera Junta) of government.

With the power of the Crown transferred to the Regency Council in
Cádiz, and besieged by French
troops, a power vacuum existed and, on
May 25,
1810, the
First Junta was created in
Buenos Aires, removing
Viceroy Baltasar Hidalgo de Cisneros from authority the same day. The junta, presided by
Cornelio Saavedra (1760-1828), included
Mariano Moreno (1778-1811) and
Manuel Belgrano (1780-1820) and was later expanded to include deputies from the other provinces (
Junta Grande or Big Junta).
It was supposed that the revolutionary leaders remained 'nominally' loyal to the
Spanish King, but claimed the right to elect their own authorities (), instead of having a
viceroy appointed from Spain. Officially, the Junta was meant to keep the sovereignty of the King, but acted in the exact opposite. They attempted to gain support from the territories of the Upper Peru (Alto Peru) located in the border next to the
Viceroyalty of Peru.
Armed Conflict
Two campaigns were ordered by the Junta Grande in order to gain support for the revolutionary ideas of Buenos Aires.
★ 'Alto Perú campaign' (1810-1811): The improvised militia was commanded by
Antonio González de Balcarce and tried to penetrate the intendencies of the Upper Peru. The militia first engaged in combat with the Spanish army in the Battle of Suipacha and it was a victory for the Argentines. But the campaign would end unsuccessfully due to the second battle: the
Battle of Huaqui. There, the militia was outnumbered and suffered a terrible loss.
★ 'Paraguay campaign' (1810-1811): Another militia, commanded by
Manuel Belgrano, made its way up to the Intendency of
Paraguay. The first battle was fought in Campichuelo and the Argentines claimed victory. However, they were completely outnumbered in the subsequent battles of
Paraguarà and
TacuarÃ. This campaign was also ended in failure.
Violent internal disagreements and the undesired outcomes of the campaigns, led to the replacement of the Junta by a triumvirate in September 1811; see
First Triumvirate (Argentina). The new government decided to promote another campaign to the Upper Peru with the reorganized Northern Army.
★ 'Second Alto Perú campaign' (1812-1813): Manuel Belgrano led the Northern Army to victory in the Battles of Tucuman and Salta in the north of present-day Argentina. These cities have remained under the Argentine government ever since. Again, they were stopped in Upper Perú in the battles of Vilcapugio and Ayohuma (today's
Bolivia). In order to prevent the Spanish from getting supplies or taking prisoners in the city of
San Salvador de Jujuy, Belgrano ordered the evacuation of the people and the burning of anything else left behind. This is known as the
Jujuy Exodus.

San MartÃn wrapped in the flag.
During the campaign, the Triumvirate established recently arrived from Spain
José de San MartÃn as Lieutenant Colonel and ordered him to create the professional and disciplined cavalry unit called Granaderos. The same division helped the revolution that collapsed the government and elected a
Second Triumvirate (Argentina) in the late 1812.
In
January 31,
1813, a Spanish squad coming from
Uruguay landed near the town of San Lorenzo, in the Santa Fe province. The Second Triumvirate urged San MartÃn to stop this attempt to reconquer Buenos Aires. The Granaderos division met the Spanish in the town's convent and made an easy victory on
February 3 in the
Battle of San Lorenzo. After this battle, the Second Triumvirate awarded San MartÃn the rank of General.
Fearing another naval attack, a general assembly was called (
asamblea del año XIII) in
Buenos Aires on
February 27, to discuss future military campaigns. It was finally decided to dissolve the Triumvirate status and to create a new regime of a one-person government. The same assembly elected the first Supreme Director in
January 31,
1814:
Gervasio Antonio de Posadas. Posadas decided to create a naval fleet with the help of
Juan Larrea and appointed
William Brown as Lieutenant Colonel and Chief Commander on
March 1,
1814. This tiny fleet engaged in combat with the Spanish ships on the coasts of
Montevideo in the
Action of 14 May 1814 and defeated them three days later. This action secured the coast of Buenos Aires and William Brown was awarded the rank of Admiral.
Supreme Director Posadas was replaced by
Carlos MarÃa de Alvear the next year, on
January 11,
1815, and was quickly followed by
Ignacio Ãlvarez Thomas on April 21. Ãlvarez Thomas appointed Alvear as the new General of the Northern Army to replace
José Rondeau, but officials would not recognize this act and remained loyal to Rondeau.
★ 'Third Alto Perú campaign' (1815): The Northern Army, unofficially commanded by
José Rondeau , started another campaign, but this time without the authorization of Supreme Director Ãlvarez Thomas. With the lack of official support, the army faced anarchy and later would lose the aid of the Provincial Army of Salta, commanded by
MartÃn Miguel de Güemes. After being defeated in the battles of Venta y Media (October 21) and
Sipe-Sipe (November 28), the northern territories were lost. They were reannexed by the Spanish
Viceroyalty of Peru, and later became present-day
Bolivia. This unsuccessful outcome to the campaign would spread rumors in Europe that the May Revolution was over.
Despite this final defeat in the north, the Spanish Army was eventually stopped and could not advance further. With King Ferdinand back in power, an urgent decision was needed regarding independence. On
July 9,
1816, an assembly of representatives from all of the provinces (except
Santa Fe,
Entre RÃos and
Corrientes, and along with the ''Banda Oriental'', present-day
Uruguay) met in
San Miguel de Tucumán declaring the full
independence of Argentina from the Spanish Crown and provisions for a national constitution. Santa Fe, Entre RÃos and Corrientes later joined.
The following year, San MartÃn took command of the Northern Army preparing a new invasion of Upper Perú (now
Bolivia), but quickly resigned, foreseeing another defeat. Instead, he became governor of the province of
Cuyo (now the provinces of
Mendoza,
San Juan, and
San Luis). He developed a new strategy to attack the
Viceroyalty of Perú through the Captaincy of
Chile. San MartÃn largely based this plan on the writings of Sir
Thomas Maitland who was quoted to say that the only way to defeat the Spanish at
Quito and
Lima was by attacking Chile first. At this point, the Argentine War of Independence gets mixed with the
Chilean independence War as both armies joined forces.
★ 'Chile campaign' (1817): Installed in the city of
Mendoza, San MartÃn reorganized the Granderos unit along with the Army of Cuyo and crossed the
Andes Mountains to attack the Royalists in
Chile at the beginning of 1817 in the
Battle of Chacabuco. With the aid of Chilean patriot
Bernardo O'Higgins he made a triumphant entry in the liberated city of
Santiago de Chile. Argentine and Chilean armies merged in the ''unofficial'' South American Patriot Army and continued the campaign together against the Spanish division commanded by Osorio. However, their forces were surprised and very badly beaten at the Battle of Cancha Rayada on
March 18,
1818. In the confusion, a false rumor spread that O'Higgins had died, and a panic seized the patriot troops, many of whom agitated for a full retreat back across the Andes to Mendoza. Crippled after his defeat at Cancha Rayada, O'Higgins delegated the command of the troops entirely to San MartÃn in a meeting on the plains of Maipú. Then, on
April 5,
1818, San MartÃn inflicted a decisive defeat on Osorio in the
Battle of Maipú, after which the depleted royalists retreated to Concepcion, never again to launch a major offensive against Santiago.
This is considered to be the 'conclusion' of the Argentine War of Independence, but battles continued by land and sea in
Perú until 1824 when the last Spanish garrison surrendered in the
Battle of Ayacucho and Peru proclaimed its independence. These events were part of San MartÃn's own campaigning with O'Higgins and
Simon Bolivar and Buenos Aires no longer recognized his authority.
The meeting of Guayaquil
On
26 July,
1822, San MartÃn met with
Simón BolÃvar at
Guayaquil to plan the future of
Latin America. Most of the details of this meeting are secret, and this has made the event a matter of much debate among historians. Some believe that BolÃvar's refusal to share command of the combined forces made San MartÃn withdraw from Perú and resettle as a farmer in
Mendoza, Argentina. Another theory claims that San MartÃn yielded to BolÃvar's charisma and avoided a confrontation. It is widely believed that both men were members of
Masonic societies, and the outcome of the meeting might have been arranged by hidden players, however this has been denied by the Great Masonic Lodges
[1] . See
Lautaro Lodge.
Annual commemoration
Today, the ''DÃa de la Revolución de Mayo'' (
May Revolution Day) on
May 25 is an annual
holiday in Argentina to commemorate these
significant events in the
history of Argentina. These and other events of the week leading to this day are referred to as the ''Semana de Mayo'' (May Week). Argentine Independence Day is celebrated on
July 9, to commemorate the
Argentine Declaration of Independence declared in 1816.
