Barito longhouses

Puruk Cahu is where the Barito stops being a river a loaded boat can climb, and the upper Barito peoples bring rattan, resin and gold down to it.

The coast never goes beyond. In later ethnography the upper river belongs to the Ot Danum, the middle to the Lawangan and the Maanyan, the lower to the Ngaju and the Bakumpai (all later names). A note for the campaign: the Malagasy language is closest to Maanyan (Dahl 1951; Adelaar), so Barito peoples took part in Indian Ocean voyages in the first millennium; that makes this river older in the sea trade than any text of 1200 would show.

Nothing is written about these river peoples in 1200. The structure is read from geography and from ethnography of the nineteenth and twentieth centuries.

What it holds

  • The head of loaded-boat navigation at Puruk Cahu
  • The middle-river stages (Muara Teweh, Buntok)
  • Exchange of rattan, resin and gold for iron and cloth

Allies and rivals

Each longhouse deals with its neighbours by marriage, feud and trade; the coastal port deals with whichever longhouses it can reach by boat. No overall alliance is known.

How things stand that morning

Not described for 1200; the longhouses are presumed to be selling camphor, gaharu, rattan, wax, gold and iron-bartered goods to the coast as the geography dictates.

Wealth

Forest goods and gold; no figures.

Military

Boats, spears, blowpipes and shields; headhunting raids in the later record. No numbers.

Threats

  • Feuds between longhouses
  • Raiding from other rivers
  • Forest fire or flood

Places of note

  • Puruk Cahu: Head of loaded-boat navigation on the Barito.
  • Muara Teweh: Middle-river stage (position approximate).
  • Buntok: Middle-river stage.

Where the sources disagree

  • The campaign board's single name 'The Dayak of the Bornean interior' is used here for five river records; 'Dayak' is an outsider's word.

Evidence: Geography and later ethnography only; the campaign board marks it 'likely'. The ethnic names used here (Dayak, Kayan, Kenyah, Iban and so on) are later outsiders' or ethnographic names; the ethnic map of 1200 is not known and differs from the modern one.

"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.

On the map: Control points (rapids, portages) are drawn as small circles; the peoples' country is in the province records.
