The Society of Friends, commonly known as QUAKERS, is a religious group founded in England in the 17th century. They are known for their commitment to peace, simplicity, and equality. QUAKERS believe that there is an 'inner light' within each person that can be used to guide one's life. They also emphasize the importance of living in harmony with nature and the environment. QUAKERS have been influential in many social movements, including the abolition of slavery, women's rights, and the civil rights movement.
