Which emperor exempted all Roman teachers from taxation and military service?

• A. Trajan
• B. Constantine
• C. Antoninus Pius
• D. Theodosius

Answer: (C)

Educators in Rome held a crucial role in spreading literacy and supporting administration, so emperors sometimes used privileges to support teaching. Teachers, known as ludi magister, were typically subject to taxes and could be required to serve in the militia like other free men. When a policy shields teachers from these burdens, it directly encourages the maintenance and growth of schools.

Antoninus Pius is the emperor who granted exemption from both taxation and military service to all teachers, a broad and stabilizing protection for the profession. This kind of privilege helped secure the supply of educated people across the empire, reinforcing the state’s administrative and cultural needs.

The other emperors listed pursued different reforms—Trajan’s focus was expansion and public works, Constantine’s on religious and administrative changes, and Theodosius’s on religion and governance—rather than a universal tax and service exemption for teachers.
