Kramer received a papal bull, Summis desiderantes affectibus, in 1484. It directed Bishop of Strasburg (then Albert of Palatinate-Mosbach) to accept the authority of Heinrich Kramer as an Inquisitor, although the motivation of the papal bull was likely political.Darst, 1979, p. 298. The Malleus Maleficarum was finished in 1486 and the papal bull was included as part of its preface, implying papal approval for the work.Russell, pp. 229–231
