Paolo Arese served as the Bishop of Tortona from his appointment on July 20, 1620, until his resignation in 1644. Here are some key events and aspects of his tenure:

1. Appointment and Ordination: Paolo Arese was appointed Bishop of Tortona on July 20, 1620, and was ordained as a bishop on September 20, 1620 (Catholic-Hierarchy).

2. Pastoral Leadership: During his tenure, Arese was responsible for overseeing the spiritual and administrative affairs of the Diocese of Tortona. The diocese, part of the church's broader effort during that period, was focusing on implementing the reforms of the Council of Trent, which included enhancing clergy discipline, improving liturgical practices, and promoting active pastoral care.

3. Resignation and Death: He resigned in 1644, not long before his death on June 14, 1644 (Wikipedia).

No other specific major events or controversies directly linked to his administrative actions are widely documented in available historical records. However, his tenure occurred during a significant era marked by the Catholic Counter-Reformation, suggesting his work likely contributed to the broader ecclesiastical reforms of that period.
