The Right Honourable Dame Jacinda Ardern was elected the fortieth prime minister of New Zealand at the age of thirty-seven, becoming the country's youngest prime minister in more than 150 years. Since leaving office, Ardern has established the Field Fellowship on empathetic leadership. She continues to work on climate action and is the patron of the Christchurch Call to Action to eliminate terrorist and violent extremist content online. Ardern also works on a number of projects that support women and girls but considers her greatest roles to be those she will hold for life, including that of mom and proud New Zealander.
