However, during this period of Europeanization, adverse feelings towards the foreigners started spreading across Japan. Following Spain's conquest of the Philippines between 1565 and 1597, Toyotomi Hideyoshi, the supreme military/political authority in Japan at the time, began to more strongly doubt the Europeans' good intentions, and questioned the loyalty of the Christian "daimyōs". Seeing the threat that Christianity potentially posed to political stability, and to the "daimyōs" loyalty to him over the Church, he issued Anti-Christian Edicts, expelling foreign missionaries, and ordering the crucifixion of a number of prominent Catholic proselytizers and converts. However, it was not until the reign of Tokugawa Iemitsu that anti-Christian policies were more fully expanded and more permanently put into effect.
