Baskerville supported the Iranian constitutional revolution from the beginning of his arrival in Tabriz. After school, he was serving food for constitutionalists on the battlefield and criticizing the Anglo-Russian Convention with his students. Baskerville became close to Hassan Sharifzadeh, who was a literature teacher at the same school and was one of the influential leaders of the constitutional revolution in Tabriz. Sharifzadeh's assassination in 1908 deeply affected and upset him. This incident had a great impact on his joining the ranks of constitutional fighters.
