Why Nerva was a good leader?

Nerva was a good leader primarily due to his ability to restore stability to the Roman Empire after the tumultuous reign of Domitian. He implemented financial reforms that alleviated burdens on the populace and promoted social welfare, earning him popular support. Additionally, Nerva's decision to adopt a successor, Trajan, set a precedent for a smoother transition of power, which contributed to a period of prosperity and relative peace known as the Five Good Emperors. His emphasis on cooperation and inclusivity helped foster unity within the empire.
