The 13-day civil war was a short conflict between Ziółkowskiists, Panslavists and Liberals in Poland classified as a civil war which lead to the Establishment of the Polish Social Nationalist Republic and The Republic of Sorbia via the treaty of Zgorzelec and the Polish Republic of Hispaniola via the Pirate Tails exodus.
Background
In the late 2020s, the Republic of Poland found itself in an unusual predicament. The country was led by the Pis-Po coalition, headed by President Andrzej Duda, while the opposition UNP-Konfederacja coalition held the Sejm in a gridlock. Additionally, organizations outside of the government, led by Hubert Ziółkowski (the ZZ and the GS), wielded significant influence over the nation, effectively granting the opposition control over most of Poland. Allegedly, Ziółkowski had begun importing Russian weapons via the Kaliningrad Oblast and Lithuania Oblast borders with Poland.
During the period after the 2025 election and before the 13-day civil war, the only agreement reached by the government was the approval of the annexation of Lithuania in the early stages of the Russian collapse. When it became clear that the collapse was imminent, the UNP-Konfederacja party held a crucial meeting in Lódź, during which Tamara Vlasov suggested sending the GS and ZZ to intervene in the Russian collapse. The objective was to establish either a separate Russophilic Polish republic in the east or to help reunite Russia, transforming it into a puppet state with the intention of annexing it later and forming a Panslavic state. However, Ziółkowski vehemently opposed the idea, dismissing it as unfeasible and refusing to "waste his men on impossible projects." Consequently, the Konfederacja party left the coalition, leaving the opposition fragmented.
Subsequently, Vlasov orchestrated a minor officer's revolt in Silesia, with the aim of creating a separate Polish state in the east. In response, fearing oppressive measures against nationalists and Russophiles, Ziółkowski ordered the ZZ to stage a coup in Warsaw, while the GS was tasked with raiding and capturing major cities and towns to consolidate his power. However, Chief of the General Staff Rajmund Andrzejczak sided with Vlasov, predicting that the Ziółkowski coup would fail and that the non-gridlocked Sejm would impose oppressive measures against nationalists and Russophiles. A few hours later, Ziółkowski officially dismissed Andrzejczak and replaced him with Witold Basiński, a close political ally.
The remaining NATO forces in Poland were informed of the situation and pledged to bring back the Pis-Po government and Andrzej Duda. Meanwhile, Pirate Tail, an independent politician, and Poraj, as part of the Krul party, declared their own government but agreed to collaborate with Pis-Po to restore democratic elections. Recently annexed Lithuanians also seized the opportunity and rose up to reclaim their independence amidst the chaos.
Course of the war
In the western part of the country, a complex political situation emerged, with various factions including Tammyists, Ziółkowskists, and Pirate Tailsists all concentrated in the area. Meanwhile, in the east, Lithuanian separatists and Ziółkowskists and Porajists were vying for influence. In response, Hubert Ziółkowski issued orders for the ZZ, GS, and some anti-Panslavist volunteers from the All Polish Youth Organization to deal with the western front, while the Polish Army, under Basiński's leadership, and the Polish Police were tasked with suppressing the Lithuanian revolt and Porajist opposition on the eastern front.
Despite Ziółkowski's successful defeat of the Lithuanians in just five days and the Porajists in eight, the situation in the west proved to be more challenging. The majority of the army was made up of volunteers and paramilitary, making it difficult to gain control of the situation. Initially, Tammyists and Ziółkowskists worked together to root out the Pirate Tailsists, who were eventually forced to flee via the Gdańsk port. However, whilst Ziółkowskiists were focused on the east, Tammyist forces moved towards Poznań, Katowice, and were closing in on Łódź.
The Battle for Łódź proved to be a pivotal moment, with Polish police loyal to Ziółkowski and Polish army units under Basiński's command working together to push back Tammyist forces. The battle resulted in a significant victory for the Ziółkowskists, allowing them to regain control of the entire Łódź Voivodeship and Upper Silesia Voivodeship. However, the cost of this campaign was high, and Ziółkowski and Tamara Vlasov were eventually forced to sign the Treaty of Zgorzelec, initially intended as a ceasefire agreement. Eventually, due to the ongoing crisis in the east, this ceasefire was ratified into an actual peace treaty.
Aftermath
After the Treaty of Zgorzelec, Hubert Ziółkowski proclaimed the Polish Social Nationalist Republic in Warsaw. In a few months, Tamara Vlasov proclaimed the Republic of Sorbia after incursions into the collapsing Federal Republic of Germany. However, the Porajists going underground in Lithuania and Belarus and the need for Ziółkowski's police and army units to go west prevented the full removal of the Porajist element from the east, leading to the Eastern Crisis later on. Meanwhile, Pirate Tails and his supporters, who had to flee via the Gdańsk port, invaded Hispaniola, leading to the establishment of the Polish Republic of Hispaniola in Port-au-Prince.
The war also had other consequences, including the Polish annexation of Kaliningrad and the sale of Pomerania. The Polish Social Nationalist Republic was desperate for money, and the Russian Federation had sent their capital and assets to Kaliningrad amidst the collapse. With the fall of Kaliningrad, the last remnant of the Russian Federation ceased to exist. To gain a quick buck, Pomerania was sold to the North German People's State as part of the Treaty of Zgorzelec. In exchange, North Germany recognized Poland's eastern borders and guaranteed Polish independence.
The Annexation of the Lwów people's republic was also significant as it saw the return of eastern Galicia to Poland, the first time it was officially Polish since 1939.
Cultural Impact
In the Polish Social Nationalist republic, the war is considered as more so a resistance quelling operation akin to quelling a violent protest rather than a real war, this is only supported by the fact most of Polish troops were Police or Paramilitary groups. The annexation of Lwów was however impactful as it lead to the Lwów trials in which Volodymyr Zelenskyy was given the death penalty for crimes against humanity, due to death from the war and polonisation efforts the area has seen large Polish migration, many places in eastern Galicia are also named and themed around early 21st century Slavic anti-western politicians. The loss of Sorbia was hard for Poland but people learnt to live with it over time, although some still long for the old western borders. The war along with the Lwów-Ukraine war lead to the scary amount of influence the ZZ holds today.
