Pacifism
Pacifism was the ethical position that violence and war were immoral. Strict pacifists refrained from all forms of violence, while restricted pacifists made some exceptions, for example, in cases of self-defense. 

Pacifism often arose out of a respect for other forms of life, even hostile ones. As such, tendencies of pacifism and vegetarianism often overlapped. 

Sometimes pacifism was tied to religious beliefs, but this was not necessarily the case. As with Vulcans, secular ethics based on pure reason could result in pacifism. 

Pacifists were often looked down upon by warrior races such as the Kzinti. () 

One who attempted to maintain peace was known as a peacekeeper. In 2258 of the alternate reality, Admiral  questioned whether  had claimed to be a peacekeeper, saying he and his cronies were in fact war criminals. ()

In the late 1930s of an alternate timeline created by Leonard McCoy's escape through the Guardian of Forever, Edith Keeler lead a pacifist movement that delayed the United States' entry into World War II, thereby giving Germany the time they needed to develop the atomic bomb first and win the war.
