Luisa Luna Carrillo, one of the organisers of the event, explained who they are: "We are just a group of Mexican people living in Kraków, and some students of Latin American studies at university, who are very tired of corruption  and injustice of the political system in Mexico".

They raised their voices because of the 43 students from Ayotzinapa, who, on 26th September, were travelling to Iguala (Guerrero, Mexico) to take part in a protest. During the journey,  local police intercepted their bus and in the struggle that followed six people died, 27 were injured and 43 students were arrested. The details about what happened are not very clear and the final investigation concluded that after being held in custody, the students were handed over to the local group Guerreros Unidos ("United Warriors"), a crime syndicate that presumably could have killed them.

"It is not only because of the 43 students from Ayotzinapa, but because of the thousands dead people that have been suffering, because of all the disappeared, kidnapped, extorted and murdered people in Mexico", continued Luisa Luna Carrillo who explained that only in 2013, more than 10,000 people died because of the organised crime in Mexico.
