The International Peace Bureau (IPB) is a global organization dedicated to promoting peace and disarmament. Founded in 1891, it is one of the oldest peace organizations in the world. The IPB works to raise awareness about the dangers of war and militarization, advocating for peaceful conflict resolution and the reduction of military spending. The organization brings together various groups and individuals who share a commitment to peace. It engages in campaigns, research, and education to influence public policy and promote international cooperation. The IPB is also associated with the Nobel Peace Prize, having received it in 1910 for its efforts in fostering peace.
