NEW DELHI (Reuters) – A saffron-robed Hindu holy man was sworn in on Sunday to lead India’s most populous state, sealing what appears to be a shift in course by Prime Minister Narendra Modi that could redefine the world’s largest democracy as a Hindu nation.

The choice as Uttar Pradesh chief minister of Yogi Adityanath, a firebrand Hindu ascetic with a history of agitation against minority Muslims, stunned observers who said it marked a departure from the platform of development for all on which Modi rose to national power in 2014.

“Modi is saying India is a Hindu country and shall remain so,” veteran journalist and commentator Shekhar Gupta told Reuters.

“Hindus will rule, so you had better behave.”

A spokesman for Modi’s Bharatiya Janata Party (BJP) however said the government did not make any distinction between citizens on the basis of religion.

Adityanath, 44, was elected by state lawmakers on Saturday, a week after the BJP won a landslide victory in Uttar Pradesh by mobilising the Hindu vote. The BJP won the biggest majority for any party in the state legislature in 40 years.

He took the oath of office at an open-air ceremony in the state capital Lucknow on Sunday, before shaking hands with Modi and other BJP elders who attended.

After the ceremony, Modi said in a tweet: “Our sole mission and motive is development. When U.P. develops, India develops.”

The BJP fielded no candidates from the Muslim minority that makes up 19 percent of the population in a state with a population of 220 million that is home to 15 percent of the world’s poor. If it were a country, Uttar Pradesh would be the world’s fifth-most populous.
