History of Manu’a Cession Day (in lieu)
The Samoan islands were formed approximately a million years ago by volcanic activity and were only discovered by Europeans in 1721 when a Dutch trader named Jacob Roggeveen stopped by on his route to another region to trade with the islanders. The islands were largely populated by various Polynesian tribes before the discovery — and subsequent entrance of additional Europeans. Historians believe that this location has one of the world’s earliest surviving Polynesian cultures, which arrived around 1,000 B.C.
The colonial powers began to covet this luxuriant region and its wealth almost two decades after its discovery. In the late 1800s, a conflict erupted amongst the main rivals — the Germans, the English, and the Americans — that would last until 1899, following a long civil war. Nine islands in the west were given to Germany, while the eastern islands became a U.S. colony and naval base. However, the High Chiefs of Manu’a islands did not wish to become a United States territory, even if they were to be incorporated — meaning a place where only select portions of the U.S. Constitution apply and which are not incorporated into the U.S. territory. So, the Manu’a High Chiefs opted out of this agreement, at least initially.
When they finally agreed to cede control, the region was governed by the U.S. Navy until 1951, after which it was supervised by the Department of the Interior (D.O.I.). Samoans from this region observe the day Manu’a swore allegiance to the U.S. with events, talks, and various activities each year.
