Spanish colonization of Chile begins in earnest in 1541, when Pedro de Valdivia founds Santiago on behalf of the Crown, establishing Spanish rule across the fertile central valley. But Spain never manages to subdue the Mapuche south of the Biobío River, who hold that frontier through the Arauco War for well over 250 years of the colonial period — a genuinely distinct story next to most of Spain's other American possessions, where conquest was far more complete.
Independence follows a hard road: after a 1814 royalist reconquest ends the short-lived “Patria Vieja,” Bernardo O'Higgins and José de San Martín lead a combined Chilean–Argentine army across the Andes in January 1817, and O'Higgins proclaims Chilean independence on 12 February 1818 under essentially the same star-and-stripes flag still flown today. What follows is, by regional standards, an unusually long and stable run of constitutional government — punctuated by the War of the Pacific (1879–84), in which Chile defeats an allied Peru and Bolivia and annexes Bolivia's Pacific coastline, a decisive and still-sensitive episode in the region's own history — before that stability breaks decisively on 11 September 1973, when the military overthrows elected president Salvador Allende; Augusto Pinochet's dictatorship then holds power until a 1988 plebiscite defeat and the 1990 return to civilian rule.
Scope of this page: the lands of present-day Chile, c. 1541–present, six political entries. Chile's own modern territory was never split into separate crowned or governing entities the way some other pages in this atlas track, so — per the same rule applied elsewhere — the map below traces the whole country rather than an internal partition. Part of a larger atlas — see the linked pages at the bottom.
One long coastline, six eras
Chile’s own real border, traced whole — the country’s modern territory was never split into separately governed pieces the way some other pages in this atlas track. Press play, or drag the slider, to watch who held all of it, era to era.
This is a single-region page, not a partition map. Chile’s narrow ribbon of territory between the Andes and the Pacific was fought over at its frontiers (the unconquered Mapuche south, the annexed Bolivian coastline after 1884) but never itself divided between rival governments the way Hungary or Cyprus were. What changes here is only who held it, not how it was cut up.

Who & why: Pinochet loses the October 1988 plebiscite on extending his rule, and civilian government returns in March 1990 under elected president Patricio Aylwin. Democratic institutions and regular elections have continued without interruption since, through a series of peaceful transfers of power across the political spectrum.
What it represents: the same national flag flown since O'Higgins's 1817–18 decree — white and red bands with a blue canton and single white five-pointed star, La Estrella Solitaria (the Lone Star) — carried forward unchanged through the return to democracy.
Attestedhow we know this
Both sources date the current flag to 1817, before this era begins in 1990, so the flag was already in use at the start. Wikipedia's infobox gives the adoption as 18 October 1817; Flags of the World dates it 17 October 1817.
Not established: Only the year the current flag was adopted was compared; the design and the swatch colours were not checked against a specification.

Who & why: on 11 September 1973 the armed forces, led by Army commander Augusto Pinochet, overthrow the democratically elected socialist government of Salvador Allende, who dies during the assault on the presidential palace, La Moneda. Pinochet then heads a military government until 1990; his rule is marked by significant political repression, including thousands of forced disappearances and deaths, and by market-oriented economic reforms. He steps aside after losing the 1988 plebiscite and the 1990 transition to civilian rule.
What it represents: the national flag is unchanged — the government made no alteration to the 1817–18 design, flying the same white, red, and blue star flag as both the preceding republic and the democracy that follows. Wikipedia documents no change to the flag's design in this period but mentions Decree No. 890 of 1975 making public mistreatment of the flag a felony and the 1980 theft of the 1818 original flag by MIR members as a protest; FOTW says nothing about the period. This silence is not itself a finding of no change.
Attestedhow we know this
Wikipedia: the construction of the flag is defined, at present, by Supreme Decree No. 1,534 of the Ministry of the Interior of 1967 (adopted 18 October 1817); it mentions Decree No. 890 of 1975 making public mistreatment of the flag a felony and the 1980 theft of the 1818 original flag by MIR members. Flags of the World quotes an official publication, 'About our Flag': the layout was fixed by legislation of 4 July 1854, the star size in 1912, and 'the flag was last regulated in a law of 18 October 1967'; a contributor adds that subsequent legislation has only specified the design without altering anything.
Not established: No source describes the flag in use under the military government as such: the unchanged flag for 1973-1990 follows from both sources giving the 1967 decree as the current definition, and from neither recording a change. Wikipedia's note on the 1975 decree and the 1980 theft is not about design.

Migration & conquest:Immigration: German colonists to the south (1850s–)Immigration: Palestinian immigrants (from early 1900s)
Who & why: from independence in 1818, Chile builds a comparatively long and stable constitutional republic by the standards of newly independent Spanish America, with regular succession under a series of 19th- and 20th-century constitutions. The largest single episode of this era is the War of the Pacific (1879–84), fought against the allied forces of Peru and Bolivia over nitrate-rich northern territory; Chile wins decisively, and by the war's settlement Bolivia loses its entire Pacific coastline while Chile annexes it along with formerly Peruvian territory further north — a decisive and still-sensitive episode in the region's own history, noted here factually as part of Chile's own territorial timeline. This single flag continuity spans over 150 years, through the War of the Pacific, the early-20th-century parliamentary and presidential republics, and the Popular Unity government of Salvador Allende elected in 1970, up to the 1973 coup.
What it represents: the design made official by O'Higgins's decree of 17–18 October 1817 (the two sources give different days), with white and red bands, a blue canton and a white star; FOTW says the original carried a coat of arms. It was not unaltered: an 1854 law made the canton a square and fixed the 2:3 ratio, an 1912 law (No. 2597) set the star at half the canton's side, and Decree No. 1534 of 1967 consolidated the national emblem rules.
Attestedhow we know this
Wikipedia: 18 October 1817 official by decree; 1854 square canton and 2:3 ratio; 1912 star diameter; 1967 Decree 1534. FOTW: 17–18 October 1817 decree by O'Higgins; the original carried a coat of arms; 1854 legislation; 1912 Law 2597; 1967 Decree 1534.
Who & why: the first independence government, the “Patria Vieja” (1810–14), flies an early blue-white-yellow tricolor from 1812 before Spanish royalist forces reconquer the country in 1814. From exile in Argentina, Bernardo O'Higgins and José de San Martín organize the Army of the Andes and cross the mountains in January 1817, winning the decisive Battle of Chacabuco. O'Higgins formally proclaims Chilean independence on 12 February 1818, adopting the white-red-blue star flag that remains Chile's national flag today.
What it represents: Wikipedia says the first patriot flag, blue, white and yellow (the Patria Vieja), was reportedly raised on 4 July 1812 and formally adopted in 1813; FOTW dates it to the 1810 declaration. Spain restored its flag in 1814–17. A transitional blue, white and red flag was adopted in 1817, without legal status, and dropped within months; the current flag was made official on 18 October 1817 and presented at the Pledge of Independence on 12 February 1818. Who designed it is disputed.
Attestedhow we know this
Wikipedia: Patria Vieja flag reportedly raised 4 July 1812, formally adopted 1813; Reconquista 1814–17; a transitional blue-white-red flag in 1817 dropped within months; current flag 18 October 1817. FOTW: independence declared 1810 with the blue-white-yellow Patria Vieja; 1817 transitional blue-white-red horizontal tricolour; decree 17–18 October 1817.
Who & why: Pedro de Valdivia founds Santiago in February 1541, establishing Spanish rule across the central valley as a captaincy general under the Viceroyalty of Peru. But the Mapuche south of the Biobío River fight the Arauco War against Spanish forces for over 250 years and are never fully conquered during the colonial period — a genuinely distinct frontier story next to Spain's other American colonies, most of which saw far more complete conquest.
What it represents: Wikipedia says colonial Chile used Spanish royal symbols, including the Cross of Burgundy, and that in 1785 Carlos III set a red-and-yellow flag for Spanish Armada ships. The drawing is a simplified approximation, not a flag specific to the captaincy.
Not yet checked against sourceshow we know this
Wikipedia: colonial Chile used Spanish royal symbols including the Cross of Burgundy; 1785 flag for Spanish Armada ships. Flags of the World's Chile pages (history, variants) start with the Patria Vieja of 1812 and, for 1814-1816, say only that the relevant Spanish flags were used during the Reconquista.
Not established: Only Wikipedia ties the Cross of Burgundy to colonial Chile; FOTW's Chile pages say nothing of 1541-1810. A general Spanish source for the cross (FOTW's Spain pages) does not mention Chile. The drawing is still a simplified approximation.

Who & why: before Spanish contact, the territory of present-day Chile is home to the Mapuche across the central-south, the Diaguita in the north-central valleys, and other distinct peoples including the Atacameño, Aymara, and Chango further north, along with the Selk'nam and other groups in the far south. No single polity governs this territory, and no central authority unites these peoples before 1541.
What it represents: no securely documented flag survives from this era; these were not flag-using societies in the European heraldic sense, and no banner can be honestly attributed to any of them. Shown here blank rather than invented.
