During the last forty years there has been a remarkable resurgence in interest by 16th-century historians in the Strasbourg Reformer, Martin Bucer (1491-1551). The components and originality of his thoughts and his actions, as well as the reality of his ideas are emerging more and more. This is largely due to the new edition of his works undertaken by an international committee, established in 1952. This edition is divided into three sections: Opera Latina (of which 5 volumes have appeared since 1953: vols. 1-3, 15 and 15 bis); Deutsche Schriften (10 volumes since 1960: vols. 1-6, 3, 7 and 17); Correspondance (vol. 1, 1979). The present second volume of the Correspondance (1524-1526) essentially covers five themes: 1) the controversies with the Roman church, 2) the evangelical propaganda, especially in the Roman speaking countries, 3) the sacramentarian dispute and the search for reconciliation, 4) the Peasant war and 5) the beginning of the anabaptist crisis.
