The
Second Samoan Civil War occurred between 1898 and 1899 because of conflicts among high-ranking Samoan chiefs and the influence of Germany, the United States and the United Kingdom for control over the Samoan islands. The
Tripartite Convention of 1899 ended the Second Samoan Civil War and was signed between the United States, the United Kingdom, and the German Empire partitioning the Samoan islands under German and U.S. control. The Samoan Islands had also experienced political instability and conflict among rival chiefs. U.S. representatives in the region engaged with local chiefs to persuade them of the benefits of ceding the territory to the U.S. The chiefs agreed and the treaty was formally signed on April 17, 1900, in the Gagamoe area in Pago Pago. The first
American flag was raised later that same day on Sogelau Hill in
Fagatogo. It was ratified by the
United States Congress by the
Ratification Act of 1929 officially incorporating Tutuila into what is now American Samoa. This treaty marked the beginning of American Samoa as a U.S. territory. Initially, the U.S. Navy governed the island for over fifty years before the territory became self-governing. American Samoa remains an unincorporated territory of the United States. Samoa's earliest inhabitants arrived as early as 1500 BC, and its history includes notable events such as the arrival of missionary John Williams in the 1830s and significant interactions with European and American traders. The involvement of foreign powers often led to conflicts and political changes, culminating in the treaties that shaped modern American Samoa. ==Later events==
