The Augsburg Confession is the confession of faith, which was submitted to His Imperial Majesty Charles V at the diet of Augsburg in the year 1530. This is one of the most important documents from the Lutheran reformation. Charles V had asked a number of Germans to explain their faith in the hope of bringing about religious and political unity in the Holy Roman Empire. The Augsburg Confession gives 21 basic articles of faith and seven articles that are listed as Disputer Articles Listing Abuses That Have been Corrected. The Apology of the Augsburg Confession was a response to the Catholic "Confutation of the Augsburg Confession" which was written to answer the Lutheran Augsburg Confession. Melanchthon wrote this as a defense of the original Confession, and a refutation of the Confutation that Emperor Charles V had commissioned.
