Pope John Paul II, during a meeting with youth in 1985, announced the establishment of World Youth Day, a gathering intended to encourage young people to embrace their faith while also fostering a sense of global fellowship among Catholics. By inviting young Christians from different countries to join in a shared experience of worship and celebration, the pope emphasized the importance of youth in the church’s mission. He believed that young people are essential to the future of the Catholic Church and wanted to create a platform where they could express their beliefs and connect with one another.

The inaugural World Youth Day was set for 1986 in Rome, Italy, in conjunction with the church's Year of the Youth. This gathering not only aimed to revitalize faith among young Catholics but also served as a response to the needs of a changing world, where young people often faced numerous challenges, including socio-economic issues and shifting cultural narratives. Throughout the event, participants engaged in prayers, reflections, and discussions about faith, fostering a spirit of hope and community. The choice of Rome as the initial location underscored the historical significance of the city as the heart of the Catholic Church.

Since its inception, World Youth Day has become a biennial event, with gatherings held in various cities around the globe, each promoting themes relevant to the experiences and challenges faced by youth today. This initiative signifies an ongoing commitment by the Catholic Church to engage with younger generations and provide them with the tools and support to navigate their spiritual journeys in a complex world. With each gathering, the event continues to nurture intergenerational dialogues and strengthen the global Catholic community.
