The Christchurch Call to Action Summit (also called the Christchurch Call) was a political summit initiated by then New Zealand Prime Minister Jacinda Ardern that took place on 15 May 2019 in Paris, France, two months after the Christchurch mosque shootings of 15 March 2019. Co-chaired by Ardern and President Emmanuel Macron of France, the summit aimed to "bring together countries and tech companies in an attempt to bring to an end the ability to use social media to organise and promote terrorism and violent extremism".^[1][2] World leaders and technology companies pledged to "eliminate terrorist and violent extremist content online";^[3] 17 countries originally signed the non-binding agreement,^[4][5] with another 31 countries following suit on 24 September the same year.^[6] The pledge consists of three sections or commitments: one for governments, one for online service providers, and one for the ways in which the two can work together.^[7][8]
