What it is
Maximilian I composed a personal act of consecration written in his own blood, dedicating himself and the Duchy of Bavaria to the Virgin Mary at the shrine of Our Lady of Altötting during the Thirty Years' War, and concealed it beneath the miraculous image in the altar of grace. He travelled to Altötting with his entire court to place Bavaria under Mary's protection at one of Germany's most ancient and revered Marian shrines. The letter survives to this day, preserved in the base of the tabernacle beneath the Black Madonna, and remains the most extraordinary personal devotional document left by any Wittelsbach ruler. It exemplifies the Marian program of Bavarian state religion in its most intense form and stands as a monument to princely piety under existential political crisis.
Why it still matters
The tradition of personal or communal Marian consecration that Maximilian enacted continues in Catholic spirituality today, most famously through the Consecration to Mary in the tradition of St. Louis de Montfort; his example is instructive for any Christian leader bringing their responsibilities before God in prayer.

Spiritual Exercises (Exercitia Spiritualia)
The foundational Jesuit method of prayer and discernment composed by the Spanish-Basque Ignatius of Loyola, structuring a four-week guided retreat through meditations on sin, the life of Christ, the Passion, and the Resurrection. Its Habsburg connection runs deep: Joanna of Austria (1535–1573), daughter of Charles V and sister of Philip II, was secretly admitted to the Society of Jesus under the alias 'Mateo Sánchez' after undertaking the Exercises under the direction of Francis Borgia, former Duke of Gandia and a close Habsburg courtier—making her the only woman ever enrolled in the Jesuit order. Philip II was unaware of his sister's membership, yet the Ignatian network shaped the spiritual climate of the court from within.
Peter Canisius: Manuale Catholicorum (Manual of Catholics)
A comprehensive Catholic devotional manual for personal prayer published by Canisius near the end of his life in Fribourg in 1587, with the full title Manuale Catholicorum. In usum pie precandi, containing prayers for all hours and occasions of the Christian day and year. Canisius had maintained deep ties to Bavaria since the 1550s through his foundational work at Ingolstadt and his close relationship with Duke Albert V, and his devotional writings circulated throughout the Wittelsbach court's spiritual network. William V's documented devotional reading habits and his intimate Jesuit connections make his household's use of the Manuale plausible, though no named ownership record has been located. It represents the mature expression of Canisius's vision of a fully Catholic lay prayer life.
Thomas à Kempis: De Imitatione Christi (The Imitation of Christ)
Perhaps the most widely read Christian devotional work after the Bible, the Imitation of Christ counsels interior piety, Eucharistic devotion, and detachment from worldly ambition — values promoted at both the Wittelsbach Counter-Reformation court and in Erasmian Lutheran circles in Saxony. The Jesuits recommended it throughout their German mission work, making it a standard text in the Bavarian court milieu under Albert V and William V; Luther himself was formed in the Devotio Moderna tradition from which it springs. No single Wettin or Wittelsbach ownership record has been located, and the dual-house listing reflects the near-universal presence of the text in every German Catholic and Erasmian Protestant court of the period rather than documented patronage.
