Rajang longhouses

The Rajang is Sarawak's great river.

Boats can run from the sea to Kapit; above it the Pelagus rapids, a long staircase of broken water, stop any boat not handled by men who know it, and beyond lies the Balui and the gathering place at Belaga. The rapids are worth more to the upriver peoples than any fort. The peoples above are later known as Kayan, Kenyah, Kejaman, Sekapan, Punan Bah and others, with the Iban a much later arrival.

The coast buys from them and does not rule them.

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

  • Pelagus rapids and the carrying round them
  • The Balui forks at Belaga and the footpaths to the Baram and the Kapuas watershed
  • The sale of camphor, gaharu and gold downriver

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, 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

  • Kapit: Last stage a coasting boat reaches before the rapids.
  • Pelagus rapids: Staircase of broken water; the wall between coast and the Balui.
  • Belaga: Gathering place at the Balui forks.

Where the sources disagree

  • The campaign board entry id sibu-rajang-forks (Sibu) is a town record; the river's tide limit is kept as a point there.
  • 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.
