Il Nuovo Postiglione - Indian rival royal factions clash outside palace

Police officers surrounded the 450-year-old City Palace in Udaipur after the unrest on Monday night when the older brother Vishvaraj Singh -- head of the historic royal family of Mewar -- was blocked from entry by his younger brother, Arvind Singh.

But top district administration official Arvind Kumar Poswal told reporters Tuesday that the "law and order situation is well under control" and that "talks are ongoing with palace representatives".

Government authorities backed by the police intervened to take temporary control of the area, he said.

Vishvaraj Singh, a state lawmaker for Prime Minister Narendra Modi's ruling Hindu-nationalist party, was anointed as successor of the Mewar royal family after his father died this month.

To take up his post, Vishvaraj needed to pray at a family shrine inside the City Palace fort, which is managed by a trust controlled by his estranged younger brother.

There have been long-running arguments between the brothers rooted in property disputes, according to the Times of India.

Udaipur's City Palace is a hugely popular tourist attraction, a sprawling complex with a flamboyant white facade.

It lies close to another royal residence, Udaipur's Lake Palace, which has been converted into a luxury hotel and featured in the 1983 James Bond spy film "Octopussy".

India's maharajas, who once ruled over around 140 million people across 565 princely states, saw their powers diluted after the country's independence from British imperial rule in 1947.

But while they became ordinary citizens in the eyes of the law, many of the families retained their social grandeur and influence -- and continue to be revered as royalty by their local populations.

Some families also shifted into politics.

They include Jyotiraditya Scindia, a lawmaker and communications minister -- who is also the grandson of the last ruler of the princely state of Gwalior.
