New Zealand Prime Minister Jacinda Ardern helped honor the memory of Nelson Mandela at a peace summit for the late South African leader.
Mandela, who led South Africa's transition from the apartheid system of white minority rule over the majority black population was a "living embodiment of the United Nation's values," Ardern said.
In the year since she took office, Ardern, 38, has enjoyed unprecedented global attention for a leader from this nation of fewer than 5 million people.
Yet at home, she's faced political pressure as she tries to keep control of a coalition government that sometimes threatens to come apart.
Internationally, Ardern in many ways offers a counterpoint to President Donald Trump: She is young, liberal and espouses an empathetic approach to leadership.
She's also pushed the boundaries for women by becoming just the second world leader in modern times to give birth while in office.
