The First Canoe: When Was Easter Island Settled?
When was Easter Island first inhabited? A timeline of settlement dates, from ancient banana remains to the strongest evidence around 1200 CE.
TL;DR
- Around 1200 CE is the strongest answer for permanent Polynesian settlement of Rapa Nui.
- Earlier published suggestions include 450 BCE, 50–100 CE, and the familiar 300–400 and 800–1000 CE chronologies. Their evidence varies substantially.
- Banana remains associated with dates around 1730–800 BCE are a striking dating problem: the bananas themselves were not dated.
- Genetic evidence establishes American–Polynesian contact before European arrival. Its dates concern encounters between populations, rather than the first habitation of Easter Island.
When did the first canoe reach Easter Island? #
A banana is a strange place to begin the history of Easter Island.
The statues usually get there first. Long faces, heavy brows, stone ancestors standing against an enormous ocean. They make the island look like the last surviving room of a much older world. But a cultivated plant asks a more intimate question. Somebody had to bring it.
In 2013, researchers studying sediment from Rano Kau, one of the island’s volcanic craters, reported microscopic banana remains in layers containing plant material thousands of years old. The associated dates reached back to roughly 1730–800 BCE. If those dates securely dated banana gardening, the island’s history would begin far earlier than the familiar Polynesian settlement story. They do not securely date it. The distinction is small enough to disappear in a headline and large enough to move the first canoe by three thousand years. (Horrocks et al., 2013.)
The best-supported settlement date is around 1200 CE. Excavated occupation deposits, careful selection of radiocarbon samples, and a separate genetic reconstruction converge on this general period. The uncertainty concerns the edges of that settlement window and the possibility of earlier human presence. (Hunt and Lipo, 2006; Ioannidis et al., 2021.)
There is a substantial scholarly history behind the other dates. Some were once standard archaeology. Others come from pollen, charcoal, and crops preserved in crater sediments. The useful way to read them is as a timeline of proposals, keeping the evidence attached to each date.

|---|---|---|
| c. 1730–800 BCE | Horrocks et al., 2013: banana phytoliths in Rano Kau layers containing other plant remains with unexpectedly old dates. | A botanical anomaly. The bananas were not directly dated; sediment movement or carbon-related dating effects could explain the association. Paper |
| c. 450 BCE | Cañellas-Boltà et al., 2013: weed pollen, burning, and vegetation change at Rano Raraku were interpreted as human arrival. | An explicit early-settlement hypothesis based on environmental evidence. An inhabited site of this age has not been established. Paper |

The modern dates cluster because they are looking at much the same historical development. An island enters the archaeological record as an inhabited Polynesian landscape around the turn of the thirteenth century. Differences of a few decades within that cluster matter less than the gap separating it from the proposed BCE arrivals.
Why did Easter Island’s settlement date change? #
A radiocarbon date is a date for a specimen. Turning it into the date of a voyage requires another step: showing how the specimen belongs to the people whose arrival we want to date.
Wood is an obvious trap. The carbon in a piece of timber can have been fixed long before somebody burned it. An old tree can therefore produce old charcoal in a younger campfire. Where that charcoal lies matters too. A sample beneath material dug from a ditch does not automatically date the first people who lived on the island. Hunt and Lipo’s reassessment made the reliability of these associations central to the settlement chronology. (Hunt and Lipo, 2006.)
This was more than a debate over which numbers to keep in a spreadsheet. Researchers could return to the collections and date better material. In 2021, a study revisited residential sites near Rano Kau that had helped support an early chronology. New dates placed their early use in the thirteenth to fifteenth centuries. A particular piece of the older settlement story could be tested, and its calendar changed. (Mulrooney et al., 2021.)
The resulting history is compressed. Settlement around 1200 leaves roughly five centuries before the Dutch expedition of 1722. The famous monuments belong within the history of those Polynesian communities. Modeling of their stone platforms, the ahu, finds a major expansion of construction between the early fourteenth and mid-fifteenth centuries, with construction continuing beyond European contact. The island’s monumental landscape could grow within centuries of its settlement. (DiNapoli et al., 2020.)
The family resemblance between Marquesan tiki and Rapanui moai fits that wider Polynesian history: related traditions carried across the ocean and developed into distinct island forms.
What do the ancient bananas actually tell us? #
Crater lakes preserve a different kind of history from a house or a cooking place. Pollen, charcoal, and fragments of plants accumulate in them, recording changes across the surrounding landscape. A garden can leave traces in a lake even when the garden itself has disappeared.
Rano Kau also contains floating vegetation and material washed or slumped from its slopes. The banana-bearing layers mixed clayey soils with wetland debris. Their dated specimens were remains of other plants. The authors considered both younger gardening material entering older deposits and effects that could make carbon dates appear too old. (Horrocks et al., 2013.)
The distinction preserves the discovery’s interest. Banana cultivation is part of the island’s human history; its connection to these very early dates needs an explanation. Calling the remains ancient does not finish the job of dating the garden.
The 450 BCE proposal at Rano Raraku makes a different connection. There, researchers linked a weed associated with disturbed ground to burning and forest change. They argued that people had arrived. The debate concerns whether those environmental signals establish human introduction and occupation at that time. A later published criticism challenged that inference. These are real disagreements over evidence, rather than a choice between accepting every early date and pretending nobody proposed one. (Cañellas-Boltà et al., 2013; Larsen and Simpson, 2014.)
An early landing, a short stay, and a lasting settlement would also leave different amounts of evidence. The first canoe might leave very little. A population raising children, planting crops, cooking meals, and burying its dead has many more opportunities to enter the record. The settlement date describes the establishment of that community. It need not be the date when the island first appeared above somebody’s horizon.
Where does Rapa Nui fit in the history of Polynesian contact? #
Rapa Nui sits near the end of a long eastward expansion. Lapita settlement reached Tonga around 900 BCE. Much later, voyagers explored and settled the archipelagos of eastern Polynesia. One regional reconstruction places settlement of the Society Islands in 1025–1120 CE, followed by a major outward expansion in 1190–1290. Research on islands such as Atiu also shows why exploration, colonization, and establishment can have different dates. (Burley et al., 2012; Wilmshurst et al., 2011; Sear et al., 2020.)
The ocean connected people to America as well. A 2020 genetic study found evidence of American–Polynesian contact around 1200 CE and favored an encounter elsewhere in eastern Polynesia before Rapa Nui’s settlement. A 2024 study of ancient Rapanui genomes dated American–Polynesian ancestry mixing to approximately 1250–1430 CE. Neither result identifies the beach where the encounter happened. (Ioannidis et al., 2020; Moreno-Mayar et al., 2024.)
This gives the trans-Pacific contact story a firm genetic foundation. It also gives us a useful separation of questions. The ancestry of a population can record an encounter that happened elsewhere. Dating that encounter does not automatically date the settlement of every island its descendants reached.

Rapanui tradition remembers the founding voyage through Hotu Matu’a and an ancestral homeland called Hiva. That memory belongs beside the archaeological history, without forcing it into a calendar year the tradition cannot independently supply. (Rull, 2019.)
The first canoe remains beyond our view. What comes into focus around 1200 is the community that stayed: people carrying an agricultural world across the sea, establishing families, and making a new island into home. Their descendants gave its ancestors stone bodies. The moai are the most visible part of that history. The plants brought in the canoes are among its smallest and most revealing witnesses.

Published ranges use different conventions. Wilmshurst et al.’s 1200–1253 CE gives earliest and latest likely ages under their method. DiNapoli et al.’s 1150–1280 CE is a 95.4% modeled interval. Schmid et al.’s 1221–1268 and 1245–1280 CE estimates are 68% posterior intervals, respectively excluding and including wood charcoal (Tables 3–4). In the banana paper, 3,680–2,750 cal BP means calibrated years before 1950, approximately 1730–800 BCE. It dates associated specimens rather than the bananas. ↩︎
