Who led the failed Children's Crusade in 1212?

The Children's Crusade of 1212 was characterized by the involvement of young individuals, primarily teenagers and children, from various parts of Europe. This movement emerged from a combination of religious fervor and desire for adventure, as these young people sought to reclaim the Holy Land in a manner akin to previous crusades led by adults.

Rather than being organized by established religious or military leaders, the Children's Crusade was notable for its lack of official sponsorship and direction. It was marked by a spontaneous and grassroots effort of youth who were inspired by their faith, rather than by seasoned adults or military strategists. This led to their journey being disorganized and ultimately resulting in tragedy and failure, with many participants facing hardships and exploitation along the way.

In this context, the focus on young people specifically highlights the unique nature of this crusade, making this the most accurate choice regarding the individuals who led the effort.
