The animal liberation movement or animal rights movement (sometimes called the animal personhood movement or animal advocacy movement), is a social movement. It is made up of activists, academics, lawyers, campaigns, and organized groups who oppose the use of non-human animals for any reason (in research, as food, as clothing, or as entertainment).

In some form or another, the concept of animal rights has been around for thousands of years.
Ahiṃsā, meaning non-violence, is a central principle of Eastern religions such as Buddhism, Taoism, and Jainism.
Jainism stresses non-cruelty towards animals. It doesn't allow its followers to work at zoos, cut trees, or use any fabrics which are produced through harming other living beings (including silk).
Within Europe and North America, there were many precursors of the modern-day animal rights movement.
The first animal cruelty legislation was passed in 1635. The law made it illegal to tear wool off of living sheep.
In 1822 Richard Martin, known as “Humanity Dick”, passed Martin’s Act aimed at preventing cruelty towards cattle. Martin went on to be one of the founding members of the Royal Society for the Prevention of Cruelty to Animals, the world’s first animal welfare charity, in 1824.
