The policies that John's father had pursued made the Portuguese court wealthy, the national economy stable, and the imperial military strong. This made a richly varied and interesting childhood possible for John. As a child, he was under the tutelage and heavy influence of the Jesuit Fathers Francisco da Cruz, João Seco, and Luís Gonzaga. Father Luís Gonzaga was in charge of the education of all of King Peter's children; he taught them military education, politics, astronomy, nautical studies, mathematics, and history. As John grew up, he was mentored in political affairs by Luís da Cunha, a prominent Portuguese diplomat.
