American Samoa Territory: History and Origin

American Samoa's incorporation into the United States rests on a specific sequence of treaties, naval administrations, and congressional acts spanning from 1900 to the mid-twentieth century. This page documents the structural history of the territory — its political origins, the legal instruments that defined its status, the causal forces that drew competing powers to the Samoan archipelago, and the classification boundaries that distinguish American Samoa from other U.S. territorial possessions. Understanding this record is essential for researchers, legal professionals, policy analysts, and anyone navigating the territory's unique constitutional position.

Definition and Scope

American Samoa is an unincorporated, unorganized territory of the United States located in the South Pacific Ocean, approximately 2,600 miles southwest of Hawaii. It comprises five main islands — Tutuila, Aunu'u, Ofu, Olosega, and Ta'ū — along with two coral atolls, Rose Atoll and Swains Island, covering a total land area of approximately 76 square miles (U.S. Census Bureau, American Samoa Geography).

The territory's history and origin, as a subject of public record, encompasses three overlapping domains: the pre-contact and inter-Pacific Samoan polity; the period of competing colonial claims by Germany, Britain, and the United States between 1872 and 1900; and the formal American administrative period beginning with the Deed of Cession of Tutuila in 1900 and the Deed of Cession of Manu'a in 1904.

Core Mechanics or Structure

The Treaty of Berlin (1899)

The foundational legal instrument partitioning the Samoan Islands is the Tripartite Convention of 1899, commonly called the Treaty of Berlin. Signed on December 2, 1899, by the United States, Germany, and Great Britain, the treaty dissolved the earlier Tripartite Agreement of 1889 and divided the Samoan archipelago. Germany received the western islands (modern Samoa); the United States received the eastern islands, which became American Samoa; and Great Britain withdrew its claims in exchange for territorial concessions elsewhere in the Pacific and Africa (Yale Law School Avalon Project, Tripartite Convention 1899).

The Deeds of Cession

The actual transfer of sovereignty occurred through two separate instruments:

  1. Deed of Cession of Tutuila and Aunu'u (April 17, 1900) — Signed by Samoan chiefs, this document transferred the main island of Tutuila to U.S. jurisdiction. The U.S. Navy assumed administrative control immediately.
  2. Deed of Cession of Manu'a (July 16, 1904) — The Manu'a group, governed by the paramount Tu'i Manu'a title, signed a separate cession, extending U.S. territorial claims to the eastern islands.

Ratification of these deeds by the U.S. Congress was not completed until February 20, 1929, under Public Law 70-856 — a 29-year gap that left the territory operating under executive branch authority alone (Office of Insular Affairs, U.S. Department of the Interior).

Swains Island

Swains Island was annexed separately under a joint resolution of Congress on March 4, 1925. Its inclusion extended American Samoa's jurisdictional boundary further north and introduced a distinct private landholding history, as Swains had been under the control of the Jennings family since the mid-nineteenth century.

Causal Relationships or Drivers

Three converging forces produced American Samoa's territorial status:

Strategic Naval Geography: The harbor at Pago Pago, recognized as one of the finest deep-water anchorages in the South Pacific, drove U.S. interest as early as 1872, when Commander Richard Meade negotiated an informal agreement with the Tutuila chief Mauga for exclusive use of the harbor. The U.S. Senate did not ratify that agreement, but the strategic logic persisted and shaped every subsequent negotiation.

Inter-Imperial Competition: Germany established commercial dominance in Samoa through the Deutsche Handels- und Plantagen-Gesellschaft (DHPG), which controlled copra production across the archipelago. British commercial interests operated alongside German ones. The 1889 First Samoan Civil War, in which Germany backed one faction and the U.S. and Britain backed another, produced the first Tripartite Agreement and set the structural conditions for the 1899 partition.

Samoan Internal Politics: The succession dispute over the paramount Samoan title of Malietoa between Malietoa Laupepa and Mata'afa Iosefo destabilized governance sufficiently that all three colonial powers intervened militarily by 1899. The partition resolved inter-imperial tensions but imposed external sovereignty over Samoan political structures that had operated continuously for over 3,000 years of Polynesian habitation.

Classification Boundaries

American Samoa occupies a specific and contested position within U.S. territorial law. Four classification distinctions apply:

Unincorporated vs. Incorporated: American Samoa is unincorporated, meaning the full body of U.S. constitutional protections does not automatically apply. Only "fundamental" constitutional rights extend to residents, per the Insular Cases decided by the U.S. Supreme Court between 1901 and 1922.

Organized vs. Unorganized: American Samoa is unorganized — Congress has never passed an Organic Act establishing formal civil government, unlike Puerto Rico (1900), Guam (1950), or the U.S. Virgin Islands (1936). The territory operates under a Revised Constitution approved by the Secretary of the Interior in 1967 and amended in 1967, 2013, and subsequently.

Nationality vs. Citizenship: Persons born in American Samoa are U.S. nationals, not U.S. citizens by birth — the only U.S. territory where this distinction applies. This status is governed by 8 U.S.C. § 1408 (Cornell Legal Information Institute, 8 U.S.C. § 1408). The American Samoa Citizenship and Nationality Law page details this classification in full.

Self-Governing Framework: The American Samoa Government operates under substantial local autonomy, including a bicameral legislature (the Fono) and an elected governor, but remains subject to federal oversight through the Office of Insular Affairs. The American Samoa Government Authority reference site documents the structure of territorial governance, including the executive, legislative, and judicial branches, and is the primary reference for regulatory and administrative questions about the territorial government.

Tradeoffs and Tensions

The historical record of American Samoa's origin contains unresolved structural tensions that continue to generate legal and political disputes:

Consent and Sovereignty: The Deeds of Cession were signed by high chiefs under protocols of Samoan customary governance (fa'amatai), not by a constitutionally representative body. Whether these instruments constituted full and informed consent to permanent territorial status is disputed in scholarship and in Samoan political discourse.

Congressional Non-Action: The 29-year gap between the 1900 Deed of Cession and the 1929 ratification meant that for nearly three decades, American Samoa existed in a legal interstitial zone — administered by the Navy Department without statutory authorization of its territorial status. Navy Rule Orders governed daily life, including restrictions on land alienation and on non-Samoan settlement, without legislative foundation.

The Nationality-Citizenship Gap: The classification of American Samoans as nationals rather than citizens has been challenged in federal courts. In Fitisemanu v. United States (10th Circuit, 2021), the court held that American Samoans are not automatically entitled to birthright citizenship under the Fourteenth Amendment, affirming the framework of the Insular Cases. This ruling remains contested and the subject of ongoing litigation and legislative advocacy.

Land Tenure Protections: Navy-era regulations restricting alienation of land to non-Samoans were carried forward into territorial law and remain in effect. These protections preserve communal fa'amatai land tenure but create friction with federal equal protection frameworks.

Common Misconceptions

Misconception: American Samoa was purchased from another colonial power.
Correction: The territory was not purchased. The United States acquired it through voluntary cession by Samoan chiefs (1900, 1904) and through the Tripartite Convention with Germany and Britain (1899), not through a financial transaction as occurred with Alaska (1867) or the Danish West Indies (1917).

Misconception: American Samoans are U.S. citizens.
Correction: Under 8 U.S.C. § 1408, persons born in American Samoa are U.S. nationals. They may travel freely within the United States and hold U.S. passports, but they cannot vote in federal elections unless they naturalize as citizens. No other U.S. territory produces nationals rather than citizens by birth.

Misconception: The territory has always been self-governing.
Correction: Naval administration without a civilian governmental structure persisted from 1900 to 1951. On July 1, 1951, administrative authority transferred from the U.S. Navy to the Department of the Interior. The first elected governor did not take office until 1978, 78 years after the initial cession.

Misconception: American Samoa and Independent Samoa are part of the same political entity.
Correction: They are two separate sovereign entities. Independent Samoa (formerly Western Samoa) achieved independence from New Zealand on January 1, 1962, and is a member of the United Nations. American Samoa remains a U.S. territory with no formal political union with Independent Samoa.
