The Treaty of Aitzondoa was an alliance treaty signed on between 
Izaria and 
Sedunn. Negotiated in the aftermath of the naval battle between Sedunn and 
Ubesii under the Tekarian regime, the treaty aimed to establish relations and give Sedunn the responsibility of protecting Izaria militarily in exchange for access to Izarian ports and airfields and trade benefits. It officially went into effect on December 20, 1940 after being signed on November 10th, 1949.
Background
The Treaty of Aitzondoa was negotiated and signed within the context of the wider geopolitical and military upheaval of the Great War, specifically following the decisive shift in naval power in the central Mediterranean Sea. After the non-aggression pact signed by 
Tekarai and 
Karnetvor, Izaria was established as a vassal state of the expanding Tekarian regime. This strategic annexation provided Tekarai with a critical forward naval and logistical base, granting easier and more secure access to the Mediterranean theatre. This was deemed especially crucial during a period of intense wartime supply demands and naval campaigning.
The subsequent Tekarian occupation of the Izarian archipelago was met with sustained and organized civilian resistance from the local population. Izarian citizens, subjected to martial law and treated as second-class citizens within the new regime's hierarchy, faced significant political oppression, economic exploitation, and cultural suppression. This period was marked by the forcible integration of Izaria into the Tekarian war economy, the suppression of local governance and the Izarian language in official contexts, and the militarization of the islands' infrastructure. Despite this, resistance networks conducted acts of sabotage, intelligence gathering, and coordinated civil disobedience, targeting key logistical and military installations. These actions, while costly in reprisals, demonstrated a persistent national consciousness and opposition to foreign rule.
The war in the Mediterranean shifted in October 1949, when a major naval battle occurred between the navies of Sedunn and Tekarai. The battle resulted in a significant defeat for the Tekarian fleet, crippling its ability to project power in the region and effectively breaking the naval blockade around the archipelago. In the immediate aftermath of this victory, Sedunnic forces launched an amphibious invasion of the islands, encountering remnants of Tekarian forces but being welcomed by the organized Izarian resistance as liberators. The swift military campaign culminated in the full liberation of Izarian territory by early November 1949. In this postwar vacuum, with Tekarian power broken and the need for immediate security and reconstruction paramount, the provisional Izarian government and the Sedunnic command began formal negotiations in the capital, Aitzondoa. These talks culminated in the signing of the treaty on November 18, 1949, which was subsequently ratified and entered into force on December 20, 1949.
Terms
The Treaty of Aitzondoa established a formal framework for Sedunnic-Izarian military cooperation and base access, defining the rights, responsibilities, and limitations of both parties. The treaty obligated Sedunn to assume primary responsibility for the external defense of the Izarian archipelago. In exchange for this security guarantee, Izaria granted Sedunn the right to maintain a permanent, rotational military presence on its territory. This presence was designed to serve as a strategic "trip-wire," ensuring that any act of aggression against Izaria would constitute an immediate engagement with Sedunnic forces. The treaty authorized the continuous stationing of at least one Sedunnic naval vessel with anti-air capabilities within Izarian territorial waters. A rotational garrison of Sedunnic army personnel, drawn from conscripts completing their mandatory national service, was also permitted for training and patrol duties.
Izaria granted Sedunn exclusive, long-term access to key strategic infrastructure. This included the right to operate from one designated deep-water naval facility, typically identified as the main port of Aitzondoa, and one airfield capable of handling military aircraft. Within these designated zones, Sedunn was permitted to construct and maintain necessary support structures, including barracks, equipment warehouses, fuel depots, and training grounds. The extent and modernization level of this infrastructure were subject to periodic review and mutual agreement, often reflecting the contemporary strategic assessment of both governments. The treaty mandated close day-to-day cooperation between the Sedunnic garrison and Izarian authorities. Sedunnic forces were authorized to conduct joint patrols with the Izarian Coastal Guard and to provide training and advisory support to Izarian security personnel. In periods of elevated regional tension or perceived threat to Izaria, the treaty allowed for a rapid and substantial reinforcement of the Sedunnic presence, including the temporary deployment of additional naval assets, combat aircraft, and specialized units such as signals intelligence (SIGINT) platforms.
While granting extensive military access, the treaty explicitly affirmed Izaria's status as a sovereign state. Sedunnic forces and personnel operating under the treaty's provisions were required to respect Izarian law. Specific protocols were established for the legal jurisdiction over Sedunnic personnel, typically granting Sedunn primary jurisdiction for military disciplinary matters while ceding jurisdiction to Izarian courts for major civil or criminal offenses committed off-base.
Effects
The Treaty of Aitzondoa and the sustained Sedunnic military presence it authorized produced significant and lasting effects on Izarian society and its view of Sedunn. In the decades following the treaty's signing, the public perception of Sedunn was largely shaped by the official narrative of the 1949 liberation. This fostered a general atmosphere of public goodwill and a perception of Sedunn as a reliable security partner. The visible presence of Sedunnic military assets and personnel in Izaria became an ordinary aspect of the social and physical environment, particularly around the capital and the designated base areas. This normalization contributed to a sense of external stability, which successive Izarian governments cited as having enabled a focus on domestic economic and social development. Cultural interactions arising from the long-term presence were inevitable and left discernible marks. Sedunnic linguistic terms, especially within technical and maritime contexts, were incorporated into common Izarian usage. Elements of Sedunnic cuisine were adapted with local ingredients and entered the mainstream. The prolonged contact also influenced Izarian arts and literature. Postwar literary and dramatic works occasionally explored themes of friendship, protection, and the complexities of a small nation's relationship with a more powerful ally. Furthermore, this treaty set the framework for the abolition of Izaria's centuries-old isolationist policy, where the nation would attempt to stay out of all international affairs for its own safety.
