The National Secular Society (NSS) is a UK-based organization that advocates for the separation of religion from government and public life. Founded in 1866, it promotes secularism, which ensures that individuals are free to practice any religion or none at all, without interference from the state. The NSS works to challenge religious privilege and discrimination, aiming to create a society where everyone is treated equally, regardless of their beliefs. The NSS engages in various activities, including campaigning for reforms in education, healthcare, and law to uphold secular principles. It also provides resources and support for individuals facing issues related to religious influence in public affairs. Through its efforts, the NSS seeks to foster a more inclusive and rational society.
