What is Secularism?

"Secularism espouses the cause of the world versus theology; of the secular and temporal versus the sacred and ecclesiastical. Secularism claims that religion ought never to be anything but a private affair; it denies the right of any kind of church to be associated with the public life of a nation, and proposes to supersede the official influence which religious institutions still exercise in both hemispheres."

George Holyoake was an English freethinker and one of the last persons in England to be convicted and jailed for blasphemy. He coined the term "secularism" while being an editor for the secularist newspaper "The Reasoner".
