Cheered by tens of thousands of supporters at the Smriti Upvan, the 21st Chief Minister of the country's most populous state was administered the oath of office and secrecy by Governor Ram Naik.
Phoolpur MP Keshav Prasad Maurya and Lucknow Mayor Dinesh Sharma were then sworn in as Deputy Chief Ministers -- in that order.
Twenty-two other cabinet ministers were sworn in. Among the ministers of state was Mohsin Raza, a BJP spokesperson and a former cricket player.
Dressed in his characteristic saffron robes, Adityanath, after taking oath, walked over to and sought the blessings of Advani, Joshi as well as Rajnath Singh.
Outgoing Chief Minister Akhilesh Yadav was present on the occasion and, before the event began, mingled freely with BJP leaders.
Among the cabinet ministers are BJP leaders Surya Pratap Sahi, Suresh Khanna, Satish Mahana, Rajesh Agarwal, Dharampal Singh, S.P. Singh Baghel and Ramapati Shastri.
Defectors from other parties who won on BJP ticket were also accommodated: Swamy Prasad Maurya, Rita Bahuguna Joshi, Dara Singh Chauhan, Brajesh Pathak and Nand Gopal Nandi.
"I am confident Yogiji will soon become the face of development in Uttar Pradesh. He has been a fighter for people's cause. He has declared 'Lok Kalyan Sankalp Patra' of the BJP manifesto is his agenda," Naidu wrote on Facebook.
"Unfortunate that some opponents, communalists are trying to portray him as a rubble-rouser and fringe personality. They should go through his parliamentary debates. Those reveal his seasoned thinking on various issues of governance," Naidu said.
Describing Yogi Adityanath as a politician committed to help the downtrodden, Naidu said it was "unfair" to attribute caste to him. "People of all communities are celebrating his appointment."
Referring to criminal charges against Yogi Adityanath, including attempt to murder and rioting, Naidu claimed the cases were political.
