In 1987, on the 50th Anniversary of the Bombing of Gernika, three events mark the origin and mission of the Gernika Gogoratuz Peace Research Centre.
- The Basque Parliament, on the basis of an unanimous decision, approves "To constitute a Peace Research Centre in Gernika, which allows to perpetuate the symbol and the remembrence of this historic fact", on the 10th of April, 1987 (Oficial Bulletin of the Basque Country, on the 23rd of April, 1987).
- Petra K. Kelly, member of the German parliament with the Green Party, deposits a bouquet of flowers at the Tree of Gernika, in remembrence of the victims of the Bombing. Petra Kelly embraced the significance that Gernika represented as a symbol for peace and democratic freedom and as a gesture of reconciliation on behalf of the Germans, she made a stand for establishing a Centre for Peace and Reconciliation in Gernika, on the 18th of April, 1987.
The Gernika Gogoratuz Association is founded. Its fundamental purpose is "to contribute through scientific research and reflection to the achievement of emancipatory and just peace on a word wide level and particulary in the Basque Country" (6th of November, 1987)
