Jacobus Carolus Nassau of Sacro (regnal name: Jacob I) was Emperor and statesman who played a significant role in the political landscape of Estos, specifically in the southern part of the continent. He initially emerged as a rival to the New Sarovian Empire through the rise of Sacro, but through skillful diplomacy and the efforts of Emperor William I of New Sarovia, he eventually became a valuable ally and strategic partner to Sarovian interests and eventually Emperor-Consort. Jacob was unpopular in New Sarovia, despite having jurisdiction and the legal protection over Lusophone Sarovians.

History[edit | edit source]

Early Life[edit | edit source]

Little is known about Jacob I's early life and background before his ascent to power. He emerged as a prominent figure in Sacro, a middle power located in the southern region of Estos, renowned for its strong military, rich natural resources and excellent financial prowess. The previous King of Sacro, Adolf I, passed away, Jacob was the closest male heir and would end up becoming the King of Nassau.

Reign of Sacro[edit | edit source]

He was characteristically religiously intolerant, being a devout Stefanist despite not being Sarovian, a rare instance. In his pursuit of power and influence in Estos, Jacob found himself at odds with the expanding New Sarovian Empire, a dominant force in the region. The turning point in Jacob I's reign came with the intervention of Emperor William I of New Sarovia. Recognizing the potential benefits of a friendly Sacro, Emperor William embarked on a diplomatic mission to establish an alliance with Jacob. Through a series of negotiations, the two leaders found common ground and forged a political and military partnership. As a symbol of their alliance, Emperor William offered the hand of his daughter, Princess Brianna, in marriage to Jacob.

Sacrovian Empire[edit | edit source]

Following their marriage, Jacob I became Emperor Consort of the New Sarovian Empire, effectively unifying his nation of Sacro with the Sarovian crown, which was known informally as the Sacrovian Empire. With the passing of Emperor William I and a brief reign of Princess Brianna's brother, Edward I, Brianna ascended to the throne as the Empress Brianna. Consequently, JacoI assumed the role of Emperor Consort, consolidating his power and influence alongside his wife. Jacob's previous appointment as the governor of the Sarovian 2nd Corps granted him the responsibility of overseeing both Sacro and the military affairs of the 2nd Corps. Throughout their co-reign, Jacob I and Empress Brianna dedicated their efforts to managing and strengthening their combined territories. Their leadership ensured stability and prosperity for the New Sarovian Empire and its allies, including Sacro.

Jacob was known as an ambitious overachiever, and originally attempted to domestic reformer. Jacob would attempt begin to push his wife out of affairs of state to seize absolute control for himself. In a seeming "counter-attack" by his wife, it was declared that a portion of Sacro and Sarovia would be merged to form a third kingdom, the Kingdom of Nassau, which would be part of Sarovia but led by Jacob. This ensured that upon his passing, a chunk of Sacro would be merged into Sarovia. Jacob was furious but legally unable to stop the declaration. When a Sarovian general officer Hizack Bonhart led a rebellion against the sovereignty of Jacob I in the Kingdom of Nassau and in II Corps, it led to a long and bloody conflict. Brianna managed to drag her heels in aiding the rebellion, knowing that the affairs would concern her husband more than her. During the rebellion, Brianna would appoint key allies with little talent or skill into important positions of office such as Field Marshal Marie Moonee, which irritated and caused so much frustration to Jacob being unable to bypass the appointments that he gave up almost entirely on controlling his wife's reign. In an informal agreement, Jacob agreed to concern himself with domestic affairs only within Sacro in exchange for aiding to put down Hizack's rebellion. Jacob would aid infrequently in issues of foreign affairs, but after disasterous decisions he himself made on the battlefield, he would retreat further into being a puppet Emperor.

Death[edit | edit source]

After the death of the Empress Brianna, their son, George I Vasa-Nassau succeeded to the Sarovian throne, continuing the family's dynasty. He was legally both the King of the Sarovians and of Sacro, but agreements made by the Viscount Lochland allowed Jacob I to hold onto the throne as the "Father-Emperor" and maintained his role as the administrator of the Sarovian 2nd Corps for a brief period following his wife's passing. His dedication to the governance of Sacro and the military exemplified his commitment to the welfare and security of his people. Jacob I's death marked the end of an era for Sacro and the New Sarovian Empire. His reign, characterized by diplomacy, poor military leadership, and successful alliance-building, contributed significantly to the stability and growth of the region. His legacy as a skilled statesman and partner is remembered as an important chapter in the history of Estos and the New Sarovian Empire.
