A kingdom whose river changes direction

Phnom Penh does not stand just anywhere on a river. The city stands where the Mekong, the Tonlé Sap and the Bassac meet. Once a year the Tonlé Sap changes direction. The kingdom has its calendar in the water as well.

Cambodia lies in South-East Asia between Thailand, Laos and Vietnam. The area is 181,035 square kilometres, the population 17,847,982. The capital is Phnom Penh. The official language and script are Khmer. The state is a constitutional monarchy, Buddhism is the state religion, the currency is called the riel. All of that is the political form. The geographical form is the confluence and the river that turns back.

The city of the meeting arms

At Phnom Penh the upper Mekong meets the Tonlé Sap, and the river divides into the lower Mekong and the Bassac. The capital sits on that knot, not on the seacoast and not in the mountains on the Thai border. People enter the state by roads from Thailand, Laos or Vietnam, or by the river. The river is still the older way. Phnom Penh is the capital because the waters force a city there, not because a plan set a centre in empty country.

Angkor, near Siem Reap in the north-west, is the other centre and not the capital. The temple complex stands on the World Heritage list. It recalls a realm whose political centre was not Phnom Penh. Today's kingdom governs from the confluence. The historical site and the living capital lie apart, and that is what keeps Cambodia from being reduced to the temples. The temples are stone. The capital is the knot of the rivers.

When the Tonlé Sap turns

In the dry season the Tonlé Sap flows from the great lake in the north-west toward the south-east and joins the Mekong at Phnom Penh. In the rainy season the Mekong rises, and the current turns: water runs back into the lake, and the lake spreads. The Mekong River Commission describes this reversal as the rhythm of the river system. No weir in the capital invented it. The river itself sets the calendar.

For the capital this means the water outside the door does not always point the same way. Fishers, fields by the lake and the level at the confluence depend on this reversal. A kingdom whose capital stands on such a knot is not a state that understands its geography only as a border with Thailand, Laos and Vietnam. The borders are real. The river that changes direction is the inner clock.

When the Tonlé Sap turns, the year turns. The capital stands exactly there.

Kingdom, script and two moneys

The constitution of 1993 restores the kingdom, after the time of Democratic Kampuchea. The king is head of state, Buddhism is the state religion, Khmer is the official language and script. That is the political answer to a break the rivers did not explain and which the constitution does not tell in figures. It sets a monarchy at the confluence and a script that is not the neighbours'. Thai, Lao and Vietnamese are other languages. Khmer is how the country writes itself.

The riel is the currency of the national bank. In everyday payments the US dollar is in use beside it. Two moneys in a kingdom whose river already has two directions are not a curiosity at the margin. They show that the state has set a coin of its own and the market has kept a second. Phnom Penh takes payment in both. Geographically the city remains the place where the Tonlé Sap flows either toward the Mekong or away from it. Politically it remains the capital of the 1993 constitution.

Cambodia is the kingdom at the knot of the Mekong, the Tonlé Sap and the Bassac. Once a year the river points the other way, and the lake breathes with it. Phnom Penh remains the capital all the same, Khmer the script, the riel the coin of the state. Angkor stands elsewhere. The river stands here.
