Silver Strike at Zacatecas
Spanish prospectors struck rich silver veins in the arid highlands of Zacatecas, opening a second great American silver frontier alongside Potosi. Mines, haciendas, and mission churches spread along the Camino Real de Tierra Adentro, and northern New Spain was pulled violently into the global economy. The patio process for amalgamating silver with mercury made Mexican mines enormously productive, consuming vast quantities of imported mercury.
Ignatius Publishes the Spiritual Exercises
Ignatius of Loyola's short handbook of meditations on the life of Christ appeared in print after years of manuscript circulation. The Exercises drilled Jesuit novices through weeks of guided prayer and self-examination. They would shape the interior lives of Catholic reformers for the next four hundred years. The Exercises' systematic progression became the model for Catholic spiritual formation, influencing meditation practices that persist in secular contexts today.
Interim of Augsburg
Charles V imposed the Augsburg Interim on the German Protestant princes after his victory at Muehlberg, allowing limited Protestant practices while restoring most Catholic doctrine and ceremonies. Lutheran pastors resisted and many fled into exile. The settlement collapsed within a few years when Maurice of Saxony turned against the emperor.
Anne of Cleves Comfortable Retirement
Anne of Cleves, long since divorced from Henry VIII but respected as the King's good sister, lived quietly in her English country estates. She would outlive all of Henry's other wives, attend Mary I's coronation, and be buried in Westminster Abbey, the only one of Henry's queens granted that honor.
