Pacifism is opposition to war, militarism, or violence. The word pacifism was coined by the French peace campaigner Émile Arnaud (1864–1921) and adopted by other peace activists at the tenth Universal Peace Congress in Glasgow in 1901. A related term is ahimsa (to do no harm), which is a core philosophy in Buddhism, Jainism, and Hinduism. While modern connotations are recent, having been explicated since the 19th century, ancient references abound.
In Christianity, Jesus Christ's injunction to "love your enemies" and asking for forgiveness for his crucifiers "for they know not what they do" have been interpreted as calling for pacifism. In modern times, interest was revived by Leo Tolstoy in his late works, particularly in The Kingdom of God Is Within You. Mohandas Gandhi (1869–1948) propounded the practice of steadfast nonviolent opposition which he called "satyagraha", instrumental in its role in the Indian Independence Movement. Its effectiveness served as inspiration to Martin Luther King Jr., James Lawson, James Bevel,Thich Nhat Hanh and many others in the Civil Rights Movement. Pacifism was widely associated with the much publicized image of Tiananmen Square Protests of 1989 with the "Tank Man", where one protester stood in nonviolent opposition to a column of tanks.
