The Keswick Convention is an annual gathering of evangelical Christians in Keswick, in the English county of Cumbria.
The Keswick Convention began in 1875 as a focal point for the Higher Life movement in the United Kingdom. It was founded by an Anglican, Canon T. D. Harford-Battersby, and a Quaker, Robert Wilson. They held the first Keswick Convention in a tent on the lawn of St John’s vicarage, Keswick, beginning with a prayer meeting on the evening of Monday, 28 June. During the conference—which continued till Friday morning—over 400 people attended uniting under the banner of „All One in Christ Jesus”—which is still the convention’s watchword.
In 1975 the centenary celebrations were held, with the highlight being an address by Billy Graham before some 15,000 people gathered at the town’s Crow Park on the shores of Derwentwater.
