When Thailand’s Crown Prince Maha Vajiralongkorn became the new King last week, he became the 10th monarch of his line.
His predecessor and father King Adulyadej Bhumibol, whose 70-year reign was the longest among his contemporaries, was widely loved by his people and his October death plunged the nation into mourning.
While the idea of inheriting a birthright to rule may seem outdated, there are still 43 countries around the world that recognise monarchs as their heads of state.
Since King Bhumibol’s death, the title of longest-reigning living monarch has now passed to Queen Elizabeth, who took the throne in 1952 and is the head of state in 16 Commonwealth realms — including Australia.
Associate Professor of politics and international relations at the University of Notre Dame John Rees said monarchs — even those that exercised political power — were no longer omnipotent.
“There are no state sovereigns in the world that hold power without some sort of relationship to parliament,” Associate Professor Rees said.
“The monarchies of the Middle East, such [as] in Saudi Arabia exercise considerably more power than a prime minster or president would. But even here there can be strong accountability to the parliament.”
“Monarchs wielding absolute power without accountability seem long ended.”
He said some monarchies had endured as their sovereigns continued to play a central role formally and culturally.
“The newly crowned King Vajiralongkorn of Thailand is a good example of this,” he said.
“Others remain without political power but will endure as symbols of national unity, such as the Emperor of Japan.
“Monarchs can play a spiritual role for people, almost as an expression of state-sanctioned religion.”
Australian support for Monarchy highest since 1990
Luke Mansillo, a PhD candidate at the University of Sydney’s Department of Government and International Relations, authored a paper this year which showed support for the monarchy in Australia was at its highest level since the 1990s
In 2013, 47 per cent of the population surveyed supported the monarchy, up from a low point of 34 per cent in 1998, but still down from a peak of 60 per cent in the 1960s.
Support for a republic has also declined — in 1998, 34 per cent believed Australia should “definitely become a republic” compared with 26 per cent in 2013.
Mr Mansillo said the generation of Australians who were in their teens when Labor prime minister Gough Whitlam was dismissed in 1975 and were also exposed to scandals in the royals’ personal lives in the 1990s was more in favour of a republic than their children.
“When the dignified part of state — all these people who are supposed to be the best of the best — are no longer dignified, it’s reasonable to think poorly of that,” he said.
