Battle of Kosnograd

Early History
The High Kingdom of Hajdut rebelled from the Autokratoria of Sirradra in May of 2023, but in July managed to anger the neighboring Tengalii Ejzen Kajzerryk and Aezenfjord (then a vassal of the Astrokhan-Wandenreich Empire). Sirradra, the T.E.K., and the A.W.E. issued a joint declaration of war against Hajdut, but no battle ended up being fought. Hajdut surrendered the land it had taken from Aezenfjord, and became a semi-independent vassal protectorate of Sirradra in the First Treaty of Kosnograd.

Hajdut's Disloyalty
However, Hajdut continued to cause problems and subsequently broke the Treaty of Kosnograd on several counts. First, Hajdut attempted to annex territory from the neighboring Sirradran province of Enithica-Novoros in October of 2023, against the wishes of Autokrator Undye. Second, third, and fourth, Hajdut continued to conduct foreign diplomacy without Sirradra's permission, entering into treaties with Yimernia, Ostolio, and Afios and aiding Lavdi in a war. Fifth, Hajdut failed to swear fealty. And sixth, Hajdut failed to exile known troublemakers whose exile was a condition of the Treaty. In addition to these breaches of the treaty, Hajdut also attempted to declare war on the Divine Kingdom of Sonnraya (with whom Sirradra had a non-aggression pact), was in talks with the Holy Kartek-Fjellheim Empire to secede from Sirradra and join them, and tried to provoke Lenoria to rebel from the Crownlands of Ashai with the help of the Imperial Archonate of Sylvania. When Ashai found out, Emperor Hasufel demanded 750 thousand Rathnir crowns from Sirradra in damages. Autokrator Yide (Undye) instead offered that Ashai join Sirradra in a war against Hajdut, but Ashai would later decline and even switch sides to assist Hajdut.

Sirradran Politics
In late October or early November of 2023, Autokrator Yide entertained the idea of selling Hajdut to Kartek, but the Rectors Provinciae were overwhelmingly opposed to selling land that had belonged to Cymru's empire since the Archonates of old or even the VIR, lands which were claimed to be the historic homeland of the Silvish people. At that point, war was inevitable, but as Autokrator Yide was reluctant to fight, preparations took a long time. Ultimately, in early December, the College of Rectors authorized the Autokrator to declare war, and Autokrator Yide finally declared war on the 12th of December 2023, with the intent to wipe Hajdut off the map for its treachery and diplomatic insults. Both domestic and international reactions to the war declaration were very positive, with several people congratulating Autokrator Yide and volunteering to fight on Sirradra's side.

Hajdut's Escalation
However, no battle would take place for a full month, as War Staff allowed no battles between roughly the 13th of December and the new year. In that time, former King Developed of Hajdut, an infamous schemer and scammer like his predecessor King Bryce, effectively seized control of Hajdut and swore fealty to the Fjarldom of Aatyeli. Aatyeli was ruled by Ulfaeng, an infamous and deadly mercenary company, and their leader Huskarl was intent on wreaking havoc against Sirradra for little apparent reason, allegedly threatening to destroy the Rathnir World's Fair Grounds in Dawnhold out of spite. Caseload hired Aragotha, then the largest mercenary company in Rathnir and Eldham, for the outrageous sum of 6 million Rathnir crowns. Additionally, the mercenary CosmosV2 decided to join the coalition against Sirradra just because he had felt slighted by Grand Marshal Tiller Rust of Sirradra for not naming him a commander, and with him he tried to bring his group Team Rocket. Additionally, Emperor Hasufel of Ashai, no doubt under pressure from a Boulderov entertaining rebellion, proposed that Ashai would assist Sirradra if Sirrardra were to return Istanboulder; Sirradra flatly refused and Ashai formally joined Hajdut's side (though, some groups within Ashai would nonetheless volunteer on Sirradra's side).

Sirradra's Coalition
The stress of the situation, along with fatigue after leading Sirradra for a long time, led Autokrator Yide to abdicate earlier than expected, and name Sima Bakura (BabyAce_) as his successor, but not before calling the Empire of Nieden and the TEK to arms against Hajdut, who came to Sirradra's aid almost instantly. The new Autokrator had Consul Nicodemus call upon Sirrradra's defensive allies, and the Sublime Archonate of Anníekos, the Central Ummarnu Mandate, and the Realms of Evermore answered the call. Additionally, Autokrator Sima was the leader of Yarner's Chosen, and hired the Hands of Vhagar, with whom he and past Autokrators had good relations. Furthermore, a large number of volunteers from the Imperial Archonate of Sylvania came to Sirradra's aid, as well as several from states and vassals of Ashai who favored Sirradra.

The Battle
On the 13th of January 2024, the Autokratoria of Sirradra along with her allies laid siege to the city of Kosnograd, the capital of the High Kingdom of Hajdut. International observers expected Sirradra to lose or tie the battle, but the siege was successful and a clear strategic victory.

Aftermath
After tense negotiations, Sirradra and Hajdut agreed to a peace deal in which Hajdut would be incorporated as a core province of Sirradra, and Developed would step down from Hajdut's leadership.
