Martin Luther, the most towering figure of the Reformation, was a supporter of Bibliander's efforts in Basel and the best example of a theologian who sought to learn more about Islam. Luther studied the Qur'an, albeit in its Latin version, and gave considerable attention to Islam and Muslims based on some of this study. That said, his greater knowledge did not translate into a more benevolent assessment of Islam. Many of his thoughts reflected the medieval prejudices that went before him, and his writings more often than not served to justify violence and aggression against the Turks, just as many medieval Christian constructions of Islam served to authorize violence against Muslims during the Crusades and the Reconquista.

XREF: Runs against the assumption that familiarity breeds tolerance; parallels how greater knowledge can reinforce existing frameworks.
