Modern Uruguay
AD 1825 - Present Day
Incorporating Heads of State (1825-2026)

Located in South America, the 'Oriental Republic of Uruguay' borders Brazil to the north, with Argentina filling its entire border to the west, divided from it by the Rio de la Plata (the 'river of silver'). To the east this pocket-sized state (in South American terms, at least) looks out over the South Atlantic. The capital and largest city is Montevideo, which was founded in 1724 as a military stronghold.

The colonial administrator of Rio de la Plata at the time, Bruno Mauricio de Zabala (1717-1734), felt forced to create it in order to hold back Portuguese encroachment from the early 'Terra do Brasil'. The country's name if 'Uruguay' comes from a Guarani word which means 'river where the birds live' (although other interpretations exist). The addition of 'oriental' is due to its eastern location within the Americas, and its position east of the river.

The first Europeans arrived in the region around 1516, when the Spanish navigator, Juan Diaz de Solis, was killed by the indigenous people whilst exploring the Rio de la Plata. That local resistance was strong, so colonisation in the 'Eastern Strip' (the later Uruguay) was limited until the first permanent Spanish Colonial settlement was founded in 1624.

Then a new Portuguese settlement prompted closer Spanish interest as they sought to limit the expansion of Brazil. Uruguay remained part of the Spanish colonies until 1825, administered first from the 'Viceroyalty of Peru' and then from Rio de la Plata. The first efforts towards independence were made as early as 1811, with Spanish power shown to be weakening through the 1807 occupation of Montevideo by Great Britain.

Then, in a period in which Spanish power in the Americas fragmented very rapidly, fighting broke out between Spain, Brazil, and Argentina. The Uruguay section of Rio de la Plata was seized by Brazil and renamed the Cisplatine region, but it was almost immediately lost again.

During further fighting in 1825-1827 the Cisplatine took its chance to break away from the 'United Provinces of South America' on 25 August 1825 (the country's Independence Day). It established itself as the independent republic of Uruguay by 1828 when it was finally recognised with backing from Great Britain. A constitution was established in 1830 under the president, Fructuoso Rivera.

Modern Uruguay has a population of around 3.2 million people, with a little over thirty-four percent of that total living in the capital city. It is reputed to be South America's most honest country, along with Chile, and is fully secular with no official religion. Its stability has earned it the nickname 'the Switzerland of South America'.

A period of economic and political turmoil gripped the country in the 1970s, in particular thanks to left-wing urban guerrilla attacks in the late 1960s and early 1970s. The government of the day suspended the constitution and launch a period of repressive military rule which lasted until 1985.

Since the full restoration of democracy, successive governments have liberalised the economy. Colonial towns, beach resorts, and a year-round mild climate have all contributed to a growing tourist industry.

The economic landscape in the 2020s has witnessed two distinct phases. Firstly there was a rebound in 2021 and the first half of 2022 following a steep decline in 2020 due to pandemic-related shutdowns. This rebound delivered economic growth, a reduction in the fiscal deficit, and improved employment figures, although it later levelled off.

1825 - 1827

King John VI of Portugal, under pressure from Britain, recognises the independence of Brazil. War breaks out almost immediately between the Argentine confederation and Brazil. During this the Spanish region of Cisplatine breaks away, establishing itself as the independent nation state of Uruguay (full independence is confirmed in 1830).

Juan Manuel de Rosas
Juan Manuel de Rosas gained control of Buenos Aires in 1829, following Uruguay's split from Argentine control, in a period of deep unrest in the South American states

Manuel Oribe

President. Blanco. Overthrown. Fled to Argentina.

1838

The political situation in Uruguay becomes complicated when two factions emerge; the conservative 'whites' (Blancos) and the liberal 'reds' (Colorados). Respectively, they represent countryside and city interests.

Both parties become associated with the war in the 'Argentine Confederation', with the blanco president of Uruguay favouring the Argentine dictator, Manuel de Rosas. On 15 June 1838 and with secret French backing, the colorados overthrow the president, Manuel Oribe, and he flees to Argentina.

Manuel Oribe's supporters form a government in exile in Montevideo, and Rivera goes to war against him. The Great War lasts for thirteen years, outliving Rivera's second term of office and almost outliving Rivera himself.

Map of Montevideo
The city of Montevideo was founded between 1724 and 1726 by Bruno Mauricio de Zabala, a port city by nature which faces the Río de la Plata and which today consists of tree covered avenues, quiet neighbourhood streets, and green squares and parks

1839 - 1843

Fructuoso Rivera

Second term. Died 1854.

1842 - 1852

An Argentine army overruns the country on Manuel Oribe's behalf in 1842, although the capital remains free. This is besieged from the start of 1843 and, when access to Paraguay is blocked for Great Britain and France, they declare war on Argentina and blockade its capital with assistance from Brazil.

Argentina agrees a peace deal in 1849 and 1850 with each of the two European powers. Argentine troops are withdrawn from Uruguay, although Oribe's own forces still maintain a loose siege.

In 1851 an Argentine faction opposes Manuel de Rosas in Argentina, defeats Oribe, and lifts the siege, nine years after it had begun. The following year, Rosas himself is overthrown at the Battle of Caseros on 3 February 1852, ending the war (and also slavery in Uruguay).

Battle of Caseros
The Battle of Caseros in February 1852 ended the career of Manuel de Rosas, shortly after Oribe's own defeat, as well as ending the occupation of areas of Uruguay's territory

1843 - 1852

Amid renewed conflict between the colorados and the blancos, General Flores leads an armed uprising against the blanco president, Bernardo Prudencio Berro.

1864 - 1870

As a result of Paraguay's declaration of war against Uruguay, Argentina, Brazil, and Uruguay go to war against Paraguay in the War of the Triple Alliance (which is also known as the Paraguayan War or the Great War in Paraguay). It proves to be a long and costly affair, causing more casualties than any other South American war.

War of the Triple Alliance
The War of the Triple Alliance - so destructive for Paraguay - was one of the first to be recorded by the relatively new invention of photography

Paraguay is utterly defeated, losing almost half its territory. However, Uruguay does not do much better, losing about ninety-five percent of its armed forces. Flores and Berro are assassinated on the very same day.

Jorge Pacheco Areco

President (Dec 1967 on). Colorado.

1968

President Jorge Pacheco declares a state of emergency in the face of growing attacks by the Tupamaros guerrilla movement. Since the group's first involvement in crime in the early 1960s it has grown into a Marxist force which kidnaps political figures and attacks the security forces, and it is beginning to destabilise the government.

Military control in Uruguay 1968
The 1973 relinquishing of power to the military by the new president of Uruguay, Juan Bordaberry, was seen in some quarters as a military coup as the military subsequently declined to return power to a democratically-elected president, until 1985

1972 - 1976

Juan Maria Bordaberry Arocena

President. Colorado. Ceded control.

1973 - 1984

The president cedes control of the country to the military in an attempt to end the Tupamaros movement. The plan works, and the guerrillas are crushed by the end of the year, but then the military refuses to relinquish its hold on power.

The imprisonment of opponents increases and Uruguayans flee the country in droves. The military 'elects' presidents to present a facade of legitimate rule before taking more direct control in 1981.

1976

Alberto Demichel Lizaso

Acting president (Jul-Sep only). Colorado.

1976 - 1981

2000 - 2005

Jorge Batlle Ibáñez

President. Colorado. Led during destabilisation.

2002 - 2004

Emergency measures are introduced in May 2002, including tax increases, by President Batlle in an effort to prevent Argentina's 2001 financial crisis from spilling over the border.

In August the government orders banks to close for almost a week to stop the mass withdrawal of savings. A general strike is held in protest at the economic crisis.

The World Bank in April 2003 approves loans worth more than two hundred and fifty million US dollars. In December voters in a referendum reject plans to open up the state oil monopoly to foreign investment.

Argentina's economic crisis of 2001
Argentina reined in inflation during the 1990s by linking the value of the peso to the US dollar, along with heavy privatisation, but a deep recession at the start of the twenty-first century culminated in a default and a further devaluation of the peso

The uncertainty and turmoil of these two years results in a remarkable outcome for 2004's presidential elections. The victory of the left-of-centre 'Frente Amplio' coalition (abbreviated as FA) ends one hundred and seventy years of Uruguayan government by the blanco and colorado parties.

2005 - 2010

Tabaré Vázquez Rosas

President. PSU / EPA / FA / NM. Liberal-leaning.

2009 - 2014

A former leftist rebel-turned-moderate wins the presidential election: José Mujica of the governing 'Broad Front'. After taking office in 2010 he goes on to improve the country's liberal standing even further.

His progressive reforms include overseeing the revocation of an amnesty law which had protected military officers from prosecution for crimes committed under military rule in 1975-1983.

His changes also legalise abortion for all women, allow abortions in the first twelve weeks of pregnancy, legalise same-sex marriage and, perhaps most controversially, legalise the cultivation, sale, and consumption of marijuana for recreational use as a measure to counter drugs cartels.

José Mujica became known for his modest lifestyle, donating ninety percent of his salary to charities and preferring to live on the farm which was owned by his wife, just outside Montevideo

2010 - 2015

José Mujica Cordano

President. MLN T / MPP / FA. Died 13 May 2025.

2015 - 2020

José Mujica's highly successful term of office comes to an end when the elderly politician stands down at the end of that term and Tabaré Vázquez wins the contest to succeed him within the 'Broad Front'.

Then Vázquez wins that year's elections to gain a non-consecutive second term of office (the first term being between 2005-2010). He largely continues Mujica's highly progressive liberal governance.

2015 - 2020

Tabaré Vázquez Rosas

President for the second time. FA. Died Dec 2020.

2020

Despite being diagnosed with lung cancer, Tabaré Vázquez completes his term of office before stepping down in March 2020. He dies that December.

Following elections, his successor is the conservative Luis Lacalle Pou of the 'National Party', successors to the blancos. His initial focus is on austerity and cutting costs rather than attempting to reverse the recent liberal progress which Uruguay has enjoyed.
