Ysta Treaty Pact

The Ystra Treaty Pact is an Ostrovian intergovernmental military alliance and a collective security system consisting of 3 full state members that spend an annual 1.5% of their GDP for the needs of the alliance: Pato k, Alaria, and Mêoriq with Guthjadland undergoing a partial secession from the alliance. The YTP was formed in 1989 as a response on the acceptance of Khalisia as a member of AOLPS and the victory of pro-Lostran governments in the 1986 Erigiveri legislative elections. Article 3 of the YTP, similar to the Primary Act of the AOLPS, states that 'an attack against one is an attack against all'. Member states are prohibited to join other military alliances with states that the YTP considers 'hostile' (see the 'Foreign relations' section).

YTP's main headquarters are located in Slowoksku, Patok, with the military headquarters being located in Rog, near the border with Lostra. The combined militaries of all YTP members constitute around 2.5 million military personnel, with the local nuclear arsenal being under collective maintenance under the YTP's 1992 Tagarsku initiative.

Observer states include Straskla and Pogoria. YTP also has partnerships with Coute Stanho and Rivro.

History
Following the Lostran Revolution and the establishment of the first radmat republic in Ostrovia, progressive parties have emerged all over Ostrovia and gained particularly strong followings in industrialised nations like Rivro, Khalisia and Mêoriq. Following the alarming intervention of Lostra and its eventual defeat in the Ritrish civil war, conservative nations started to form military alliances to combat the ideological threat posed by progressive powers like Lostra. One of the first of these unions - the League of Alle - succeeded in establishing an economic blockades against Lostra until it was lifted by victory of the blockaded power in the 1941 13-Day War against Mêoriq.

Following the acceleration of the Lostran nuclear research program, the Officer's coup in Dorostriv and the 1948 Pogorian general strike, Patok, Mêoriq, Vandeca, Pogoria, Guthjadland and Skorozheroda formed the Organisation of Ostrovian Nations in 1948, aiming to use diplomatic pressure to halt the alleged Lostran developments in nuclear research. Six months after the conclusion Conaça Accords, which forbid further secret development of a nuclear program for all participants, Patok attacked the Lostran borders, triggering the massive Operation Tamid. Three months later, Lostra, nearing defeat, deployed three of the five prototype nuclear warheads that were originally created for testing, later decomissioned as part of the agreement and then readied again, forcing negotiations that returned occupied land back to Mêoriq and ended the conflict. Lostra then formed the AOLPS together with Dorostriv as a defensive alliance of progressive nations.

Post-war ecomomic decline caused the shrinking of the OON and re-emergence of juidicialist and progressive movements that caused the 1955 Skorozherodan transition to democracy, 1954 protests in Patok and the Seilurok spring as well as kicking off the Liberalisation of Guthjadland. The anti-progressivist bloc found itself fractured and did not attempt to resist the influence of AOLPS until the 1988 expansion of the alliance into Khalisia, the Radmat Insurgency in Ritro and the victory of the Democratic-Progressive Party (Erigiveri) in the 1986 Erigiveri legislative elections. Following the 1998 Patok Military Excercise, the OON was reorganized into the YTP - a military alliance similar in structure to the AOLPS. After the 1991 Patok-Alaria Treaty of Friendship that ended almost a century of historical rivalry, Alaria was accepted into the YTP.
