Missionary conversion succeeded among conquered Muslims in Christian lands, not overseas

Evidence

The famous Arabic studium founded by San Ramon claimed ten thousand conversions, and particularly the conversion of the educated. The admission of missionaries to Muslim populations in southern Italy was even the subject of successful negotation between the Pope and Frederick II. These efforts measure the failure of the missions overseas. — Norman Daniel, Islam and the West, 680
