House of Esterházy
The House of Esterházy (Hétumogerian: Esterházy-ház) was a royal Veszprémic noble house that was extant since the Confederation of Hétumoger and existed as a group of elite Veszprémic Deer Archers. The House of Esterházy is described in three different time periods, the Jánosian-Sándoric Era, the Imperial Era, and the Monarchial era. The House held monarchial status over Hétumoger throughout the Confederation and later during the Empire of Hétumoger. They would eventually abdicate the throne until later being placed during the Second Kingdom of Hétumoger before going extinct at the end of the War of Nobles where all direct generation descendents of the Esterházy were put to death by the government of the First Noble Republic of Hétumoger.
The Esterházy is believed to have began with János I, who was a Deer Archer and the leader of the Veszprémic tribe. János would engage the Rédics tribe and Sió tribe during the Hétumogerian Seven Tribes War, which allowed him to create the Confederation. He would later focus the tribal focus on the Jánosian Wars against Tervingia and the area surrounding Lake Kulpalnitsa. During this time, he crowned his son, Sándor I as his successor, and established the Nemesség as a barebone structure of courtiers, social elites and tribal warlords that assisted the ruler. His son Sándor I would continue the conflict with Tervingia and would go on to establish the Empire of Hétumoger, crowning his son János II the Emperor. The identity politics surrounding the need of a court of important figures from the country to help guide the emperor started with János, and would later solidify the cultural tie of Hétumoger to a division of power that would be entrusted to several appointed figures.
In the lead up of the War of Nobles in the Second Kingdom, Zgismond I had died and his sons János XVIII and Miklós Esterházy I were in the midst of beginning a war for succession over the throne. However, the House of Ákos and House of Koháry in an attempt to prevent a successionist war called the Lakottial Conference of Andrássy, where the Second Kingdom began to experience the Antebellum Seccessionist Crisis, where several Noble Houses declared their independence from the Second Kingdom. The Esterházy saw their power divided between their own group of noble houses who stayed loyal, the Royalist Congress against the secessionist Coalition of Noble Houses. The war saw a defeat of the Royalist Congress after the Battle of Antlers Valley. It was determined by the Coalitionists that the Esterházy family was to be put to death for the ravaging of the country during the war, and subsequently rounded up all males and females that were determined to be direct descendants Zgismond and his brothers & sisters. The Massacre of Esterházy marked the end of the Hétumoger Imperial Era and the beginning of the First Noble Era in history
