Alpha International is a charity which publishes and promotes the Alpha course in 169 countries worldwide. Today it oversees not only the Alpha Course, but also a range of associated ministries including Relationship Central, Worship Central, the William Wilberforce Trust, God at Work and St Paul's Theological Centre.
When curate Nicky Gumbel took over the running of the church course at Holy Trinity Brompton in 1990, he noticed its appeal to those who would not describe themselves as Christians. The course became increasingly popular and, after the first training conference for church leaders in 1993, began running in other churches in the UK and around the world.
The Alpha Course began as an introduction to the Christian faith for new Christians attending Holy Trinity Brompton church in central London.
