Duterte (left), also known as 'The Punisher' from his term as mayor of Davao City, has promised a ruthless and controversial war on crime as the chief focus of his six-year term.

Philippines Vice President Leni Robredo also took the oath of office on Thursday, calling for unity across the country following what became a divisive election.

Large crowds turned out to show their support to Duterte in Manila on June 30. Duterte won the 2016 election with 39% of the vote.

In the lead up to the inauguration, Duterte came into conflict with both the Catholic Church and the independent press, who weren't allowed into the ceremony.

Despite remaining popular in the Philippines, analysts have speculated the new, unpredictable president could lead to cooler ties between the United States and the Philippines.

Outgoing Philippines president Benigno Aquino (center), who was elected in 2010 for a six year term, told CNN Philippines he hoped he had left the Filipino population feeling empowered.
