Andrew Báthory

Andrew Báthory, born in 1563, was a prominent Catholic priest and a significant figure in the ecclesiastical and political landscape of Eastern Europe during the late sixteenth century. He served as the Cardinal-deacon of Sant'Adriano al Foro from 1584 to 1599 and held the esteemed position of Prince-Bishop of Warmia from 1589 until his death. His lineage connected him to the influential Báthory family, being the favorite nephew of Stephen Báthory, the ruler of the Polish–Lithuanian Commonwealth.

Invited to Poland by his uncle in 1578, Andrew pursued his studies at the Jesuit college in Pułtusk. By 1581, he had become a canon in the Chapter of the Roman Catholic Diocese of Warmia, and two years later, he was appointed provost of the Monastery of Miechów. His rise in the church was marked by his appointment as cardinal by Pope Gregory XIII during a visit to Rome in 1584, followed by his installation as coadjutor bishop of Warmia.

Following the death of Stephen Báthory in 1586, Andrew was a candidate for succession in Poland and Lithuania. However, he chose to support Sigismund Vasa, another candidate, under the persuasion of Jan Zamoyski, the Chancellor of Poland. After Sigismund Vasa's election as king in 1587, Andrew played a crucial role in rallying support against Maximilian of Habsburg, who also sought the throne. His tenure as Prince-Bishop began after the passing of Bishop Marcin Kromer in 1589.

In the early 1590s, tensions arose between Andrew and his brother Balthasar Báthory against Sigismund Báthory regarding the Jesuit presence in Protestant Transylvania. The situation escalated when Sigismund's alliance with the Holy League against the Ottoman Empire led to Balthasar's execution and the confiscation of Andrew's estates in 1594. Following a series of defeats for the Holy League, Sigismund abdicated in 1598 but later returned to power.

Ultimately, Andrew and Sigismund reconciled, with Sigismund renouncing Transylvania in favor of Andrew in March 1599. Supported by Poland and the Ottoman Empire, Andrew faced military challenges from Michael the Brave, who defeated his forces at the Battle of Sellenberk. In a tragic turn of events, Andrew was captured and killed by Székely serfs while attempting to flee to Poland.
