One World is one of the cornerstones of the People in Need organisation. Since its inception in 1999, it has become the most important festival of its kind in the world and in 2007 it won a special mention from UNESCO for its contribution to human rights education.

People in Need was established in 1992 by a group of war correspondents and foreign correspondents who were no longer satisfied with simply bringing back information to the Czech Republic and therefore began sending out aid. People in Need has gradually established itself as a humanitarian organisation that aims to help in troubled regions and to support the observance of human rights around the world. In the 28 years it has been in existence, it has become one of the biggest non-profit organisations in Central Europe. It also began devoting itself to education and helping people living in social exclusion.

Every year, the One World Festival screens over a hundred quality documentaries from all over the world.
