2016 marked the 800th anniversary of the foundation of the Dominican Order of Preachers. This history sets St Dominic and his Order’s developing mission in the context of major social changes through the centuries and across the globe. The story is enriched by the contribution of major saints and leading figures such as St Thomas Aquinas, St Catherine of Siena, Girolamo Savonarola, Bartolomé de Las Casas, St Martin de Porres, Henri-Dominique Lacordaire, and Yves Congar. Particular attention is given to some of the English-speaking provinces.
