The Interallied Federation of War Veterans Organisations, known as FIDAC, was established in Paris, France, as a groundbreaking initiative to bring together war veterans from different nations. The founding meeting convened in the aftermath of World War I, a time when numerous soldiers returned home, physically and emotionally affected by the conflicts they had endured. The aim of FIDAC was to foster unity and collaboration among various national veterans' organizations, indicating a shared commitment to address the needs and rights of veterans at a time of widespread recovery and reconstruction. The event marked a pivotal moment in recognizing the importance of veterans' voices in the political landscape of post-war Europe.

Representatives from several countries, including France, the United Kingdom, and the United States, participated in the founding discussions, contributing to the collective resolution to support each other and advocate for common issues such as pensions, healthcare, and reintegration into civilian life. This international cooperation highlighted the longstanding benediction that war veterans could offer, serving as a bridge between different national narratives. The essence of FIDAC was the belief that soldiers, having shared perilous experiences, could collaborate across borders to achieve greater respect and acknowledgment of their sacrifices.
