Protestant doctrinal statement formulated in Bohemia by the Czech Utraquists (moderate Hussites) in 1575 and subscribed to by the Unitas Fratrum, Lutherans, and Calvinists in the kingdom. The document was based on the Augsburg Confession, and it upheld the Lutheran position on justification and the Calvinist interpretation of the Eucharist. Though Emperor Maximilian II withheld formal approval of the Confession, he orally guaranteed religious freedom to the Protestants of Bohemia. Eventually Emperor Rudolf II granted official recognition to Bohemia's Protestants with his Letter of Majesty (1609). Previously, the Unitas Confession (1535), introduced by Martin Luther and published by him at Wittenberg as a sign of agreement between Lutherans and Utraquists, had been presented to Emperor Ferdinand I for legal recognition, but without success.
