Uhuru Kenyatta has been sworn in as Kenya’s new president, following his victory in March against Raila Odinga.
Dignitaries and tens of thousands of people witnessed the inauguration at a stadium in the capital, Nairobi.
Mr Odinga did not attend the ceremony after his attempt to overturn Mr Kenyatta’s victory in court failed.
Mr Kenyatta and his deputy, William Ruto, face charges at the International Criminal Court relating to post-election violence five years ago.
They were on opposite sides at the time and both deny the accusations.
Sudanese President Omar al-Bashir, who faces an ICC arrest warrant over the conflict in Darfur, is not in Nairobi for the inauguration.
Mr Kenyatta is the son of Kenya’s founding father, Jomo Kenyatta, and is heir to one of the largest fortunes in Kenya.
He served as deputy prime minister, minister for trade, and finance minister under outgoing President Mwai Kibaki
The crowd, waving Kenyan flags, burst into rapturous welcome as the 51 year old took the oath of office, becoming Kenya’s youngest president.
In his inaugural address, Mr Kenyatta said he would govern for all Kenyans.
“We will leave no community behind… Where there’s disillusionment, we’ll restore hope,” he said.
The new government would abolish maternity fees in its first 100 days and children starting school next year would be given laptops, he added.
In an apparent reference to the ICC case against him, he said: “I assure you again that under my leadership, Kenya will strive to uphold our international obligations, so long as these are founded on the well-established principles of mutual respect and reciprocity.”
US and European diplomats attended the inauguration, despite warning before the election that they would have limited contact with Mr Kenyatta if he is voted into office.
Among the African leaders present for the inauguration were South Africa’s Jacob Zuma, Nigeria’s Goodluck Jonathan, Tanzani’s Jakaya Kikwete and Uganda’s Yoweri Museveni.
Mr Museveni told the cheering crowd that he wanted to applaud Kenyans for rejecting the “blackmail” of the ICC.
He supported the ICC when it was formed, but it was now being used by “arrogant actors” who were trying to “install leaders of their choice in Africa and eliminate those they don’t like”, he said.
Mr Odinga – the outgoing prime minister – did not attend the ceremony, choosing to be on holiday in South Africa instead.
