Ferdinand II of Bohemia

Ferdinand II of Bohemia (1578–1637) was Holy Roman Emperor and King of Bohemia, known for his strong Catholic beliefs. His efforts to enforce religious uniformity led to the Thirty Years' War, a major conflict across Europe that involved religious, political, and territorial disputes. His reign was marked by efforts to centralize power and promote Catholicism, which intensified tensions with Protestant nobles and other states. Ferdinand's actions contributed to significant upheaval in Europe, shaping the political and religious landscape for years to come.
