Hungary's commitment to the Axis powers was formalized with the signing of the Tripartite Pact. This agreement was seen as a strategic maneuver, aiming for military alliances with dominant powers Germany and Italy, while Japan also joined this coalition. Hungary's motivation to align with the Axis stemmed primarily from desires for territorial expansion and reclaiming areas lost after World War I. Transylvania, in particular, was a point of contention, as it had been ceded to Romania in 1920. Participating in the Axis was appealing for Hungary's government, which faced internal challenges and saw military ventures as a means to regain prestige and territory. The signing ceremony took place in Budapest, emphasizing Hungary's intentions to solidify its standing in the changing geopolitical landscape of Europe.

The Tripartite Pact was significant as it not only formalized military cooperation but also set the stage for Hungary to participate more actively in World War II. Following the signing, Hungary would contribute troops to the Eastern Front and engage in operations against Soviet forces. Hungary's alliance with the Axis also led to a tense internal political climate, where it faced pressure from both Axis and Allied powers. The implications of this pact extended beyond mere military alliance, impacting Hungary's domestic policies, societal structure, and later, its fate post-war, as the nation would face consequences for its participation in the Axis.
