Khwajah Kamaluddin was a prominent figure of the early Ahmadiyya movement and the author of numerous works about Islam, born in Punjab, India in 1870.

He was educated at the Forman Christian College, Lahore, where he was drawn to Christianity, but he was later exposed to the writings of Mirza Ghulam Ahmad, the founder of the Ahmadiyya movement, and experienced a renewed devotion to Islam. In 1893, he joined the movement and became a close disciple of Ghulam Ahmad.

During his life Khwajah Kamaluddin has written numerous books, many of which have been translated and published in English. Among these we mention The Holy Quran and the Bible, Mysticism in Islam, Islam and Civilisation, Muhammad the Most Successful Prophet, The Sources of Christianity, The Problem of Human Evolution, and The Five Pillars of Islam.

Ethics of War, the Kamaluddin’s short essay that today we propose to our readers, was written in 1901.

«To ensure peace we have often to disturb peace, and then the martial spirit that has been implanted in us by God for our safety comes into play. The protection of life and property is a common instinct, but it has often served as a pretext for oppression and tyranny».
