How much was written down

Each star is an event in the record for Outer islands, set in the era it falls in. Dense skies mean many foreign ships, missions and officials wrote things down; sparse ones mean they did not, not that less happened.

Outer islands and the Sokehs resettlement

Typhoon refugees filled Sokehs after the exile

Outer islanders “began to arrive about 1906 and were considerably augmented in 1912,” mostly Mortlockese displaced by typhoons (Riesenberg 1968). Most settled in the six villages on Sokehs Island. The 1907 Good Friday typhoon in the Mortlocks drove people first to Pohnpei, then on to Saipan (Spennemann, Melimel).

Germany declared Sokehs government land and leased it in hereditary tenure to Pohnpeians from other districts (Bundesarchiv). The 1920 Kolonial-Lexikon says families from the Mortlocks, Mokil and Pingelap had “considerably increased” Pohnpei’s population (Kolonial-Lexikon, Ponape). Riesenberg does not say the 1912 settlers got confiscated Sokehs land directly, so that link stays an inference.

A 1911–12 count found 3,190 Pohnpeians, 585 Central Carolinians and 279 Melanesian soldiers (Riesenberg 1968). By 1947 there were 1,177 non-Pohnpeians on the island, 664 of them Mortlockese (Riesenberg 1968). Only 242 Sokehs people were counted that year (Morlang, via Perlentaucher).

Kapingamarangi built a village in Kolonia

Marshallese raiders “slaughtered over half the Kapinga population in 1865” (EveryCulture). Under Japan, Kapinga men worked Pohnpei’s roads and plantations, and in 1919 they got land in Kolonia that became Porakiet. By 1997 about half of roughly 2,000 Kapinga lived in Porakiet (University of Oregon).

Pingelap’s typhoon left a genetic mark

The typhoon Liengkieki “decimated most of the island population” in 1775 (Ben Simon et al. 2004). Today 6–10% of Pingelapese have achromatopsia, a total color blindness, and up to 30% carry the gene. In one clinical study, 17 of 27 patients came from Mand, a Pingelapese village on Pohnpei.

Ngatik’s population descends from the 1837 attackers

The Lambton party of “several Europeans and twenty Ponapeans, all armed,” killed every adult man on Ngatik (Tryon 2001). Women and infants were spared, and Irishman Paddy Gorman was installed as chief for turtle shell. The outsiders who stayed formed the base of today’s roughly 500 people.

Mortlockese saw Pohnpei as a center of craft and war

In 1828 Mortlockese took Lütke’s mahogany furniture for Pohnpeian work and spoke of Pohnpeians as formidable warriors (Lütke, vol. II). They ranked Pohnpeian cloth above Kosrae’s, and Kosrae’s above their own. A Lukunor elder named Eboung drew a map that put Pohnpei first.

Outer islands through every era

Ten chapters, most recent open. Each starts with what the chapter says about Outer islands, then a spread of its events.

The contact era

1820–1885, 45 events

He found iron tools in the Mortlocks and Spanish words in the Mortlocks and Namonuito (Hezel, Truk; Lütke, vol. II). He spent only about a day off Chuuk’s reef.

In July 1837 the Sydney cutter Lambton attacked Ngatik (Sapwuahfik) in search of turtle shell (Wikipedia, Ngatik massacre). Lin Poyer says nearly every adult man was killed, while another writer says about 20 survived. The crew and Pohnpeians then repopulated the atoll, giving rise to Ngatik Men’s Creole.

1899–1914, 8 events

A severe 1905 typhoon brought famine to Pohnpei, and residents traded many guns for food relief (Habele, “German Period”). Another typhoon devastated Woleai in Yap’s outer islands in 1907. Disarmament stayed partial, which helps explain why the 1910 rebels were well armed.

About 50 exiles died and over 100 men worked Angaur’s phosphate mines (Bundesarchiv). Germany declared Sokehs government land and leased it to Pohnpeians from other districts. Mortlockese and other outer islanders also settled there from 1912 (Bundesarchiv; Riesenberg 1968).
