North-South Concordant

The North-South Concordant (NSC; : 남북 협응; : Concordante Norte-Sur; CNS; : Ipar-Hego Konkordantea; IHK), also known as The Concordant (: 일치; : El Concordant; : Konkordantea), is a multilateral  between the 9 member states. The Concordant was formally established in 1960, spawning from the North-South Defence Consortium involving private and public based in each member nation which itself formed largely along the lines of the older Crown Alliance.

The NSC's core task is cooperative security through regular military exercises, common threat response strategies and facilitation of research, development and manufacture of common armaments and technologies. While the alliance does not have a binding provision for in the event of an attack on a member party, the alliance promotes  through the development of unified threat-response strategies.

Ideologically, the Concordant is regarded as a politically pragmatic alliance based primarily around supporting the hard power of its member states and not necessarily any normative ideology. This contrasts with the League of Free Nations, which supports liberal democracy, and the International Movement for Socialism, which supports communist and socialist parties. The majority of Concordant nations are considered to be illiberal, ranging in government type from to, , and secular monarchies.

Precursors
The first ancestor of the North-South Concordant was the Crown Alliance that formed in 1896 to balance against the military threat of Teutonenland in the late-19th and early-20th centuries. Member states at the beginning of the The Grand Campaigns were Agrana y Griegro, Boaga, Tiperyn and Koryeo. Initially, the Crown Alliance remained detached from the conflict between Teutonenland and Vallis. However, once the Teutonenland offensive penetrated deep into Vallis and threatened Tiperyn's southern coast, the Crown Alliance intervened. Tiperyn deployed an expeditionary army to Vallis to halt Teutonic forces and Agrana y Griegro launched an offensive in southern Teutonenland. Boaga had previously been defeated by Teutonenland in the Boagan-Teuton War, with two-thirds of Boaga having been ceded to Teutonenland. Once war with Teutonenland and the Crown Alliance seemed eminent, Boaga joined the attack in an effort to regain its lost territories. Koryeo offered financial and other aid in the form of loans, the export of ordnance and the lease of transport ships to other alliance nations. This was the first military operation conducted by alliance.

After the end of the Great War and Communist revolution in Teutonenland, the Crown Alliance dissolved. However, Agrana y Griegro, Boaga, Tiperyn and Koryeo each quadlaterally agreed with one another to not challenge each others' sphere of influence or expeditions in Kesh. Further, in 1933, Tiperyn and Koryeo would form the North-South Defence Consortium composed of defence contractors. The mission statement of the new institution was to pool resources for the research, development and manufacture of military implements and lower barriers to the trade of materiel and defence products between nations. Ultimately, the consortium would form the basis of the North-South Concordant which was formally established in 1960 shortly after the end of the Great Kesh War. Tiperyn, Agrana y Griegro, Boaga and Koryeo were its founded members. As a dominion of Tiperyn, Naseristan ascended to the alliance in 1963. Alvakalia was the first nation outside of the direct or indirect control of a founding member to join the alliance in 1964. Svenskt joined shortly later in 1968. Meanwhile, Cipertine Hierarchy and Terres Riveraines joined the Concordant simultaneously in 1975. However, Alvakalia left in late 2019 following the Casinta Incident, when Agranan paramilitary shot and killed five Alvak nationals who were in the country as a news crew, while responding to riots in the city.

Core tenets
Members of the Concordant adhere to the following principles as stated in the alliance charter:
 * 1) Member states will not challenge or openly criticize the spheres of influence or right to sovereignty of other member states on the world stage;
 * 2) Member states will make every effort to conduct war games regularly to maintain expeditionary readiness and form familiarity between each others' armed forces;
 * 3) Member states will make every effort to standardize arms to ease manufacturing, increase commonality and benefit the collective economy;
 * 4) Member states are not obligated to come to the defence of other members in the case of outside aggression. However, member states will not conduct military operations against a member state;
 * 5) Member states will not collude with states who are conducting military operations against a member state.

Armament trade and development
Through the North-South Defence Consortium - the trade bloc subdivision of the Concordant - Tiperyn, Koryese, Boagan and Agranan defence contractors often cooperate in the research and development and manufacture of armaments and defence technologies. This institution has lead to the standardization of a large portion of each member states' ordnance and firearms and shared technologies since the 1930s. Two of the most significant standardizations as a result of this consortium were the adoption of the rifle cartridge in the early 20th century and the development of Griphon air superiority fighter in the 21st century.
