After 18 months the Alternatives to Religion cataloguing project reaches its conclusion this week. The project has unearthed the histories of three influential non-theistic organisations, making their archives freely accessible for the first time.
Throughout the 20th century the National Secular Society kept records of local secular society branches and affiliated groups. This included organisations both in the UK and abroad. From the National Secular Society archive, this photograph captures the Birmingham Branch on their annual outing in 1926.
