King Saint Stephen of Hungary wished to be crowned on the day of the Assumption in the year 1001. He had an image of Mary embroidered on his royal cloak, and near his palace he built a splendid church dedicated to the Virgin Mary.
On the day of the Assumption 1038, the king renewed the act of consecration of his country to the Virgin and offered her his crown, asking for her protection over the young Church of his country.
The first Bishop of Csanád (d. 1046), the Benedictine monk Saint Gerard Sagredo, invited the Hungarians to invoke the Virgin as "Magna Domina," "Great Lady of the Hungarians," giving her all the honor that had formerly been offered to the pagan goddess of fertility and life, "Boldog Asszony."
The prayer of the Angelus, recited three times a day, at dawn, noon and in the evening, was introduced in Hungary after the victory over the Turks in Belgrade in 1456. Later, Budapest fell under Ottoman rule (Turkish Muslims) from 1541 to 1686.
Following its liberation in 1693, Emperor Leopold I renewed the national act of consecration of Hungary to Mary.
