(CNN) Korean boy band BTS became the first ever K-Pop group to address the United Nations this week when it told young people to believe in their own convictions and voices.

The group of seven made history by delivering a three-minute speech during the launch ceremony of UNICEF's global partnership Generation Unlimited at the 73rd session of the UN General Assembly in New York on Monday.

Formed in 2013, BTS is one of the most popular Korean bands in the world, with more than 13.3 million followers on Instagram.

The group previously worked with the UN on awareness and fundraising campaigns. In 2017, BTS joined with the Korean Committee for UNICEF to establish Love Myself, which works with UNICEF's global #ENDviolence to advocate against against youth violence.

"Last November, BTS launched the 'Love Myself' campaign with UNICEF, building on our belief that 'true love first begins with loving myself'," said Kim Nam Jun, the band's leader, according to a UN press statement.
