It was not long after Urban II launched the First Crusade in 1095 that the ideas of crusading were being used within the borders of Christendom; as early as 1100, Landulf of Milan likened freeing the Church from simoniacs to the crusade, and three years later Robert of Flanders was offered remission of his sins if he fought against the people of Liége. Crusading began to be used as a way of removing religious and political enemies and troublemakers, either by launching crusades against them or, as with Thomas Becket's murderers, by sending them to the Holy Land to fight. These developments were not confined to the most prominent crusading countries in Europe, but were expanded over time to include places, like Wales, which tend to be overlooked when the growth of the use of crusading in politics is considered. Although Archbishop Baldwin's preaching tour of 1188 has been analysed on numerous occasions, notably by Huw Pryce and Peter Edbury, it has not yet been put into the context of developments in the use of crusading in Anglo-Welsh relations over the century that followed. This paper will seek to remedy this by considering how the tour tried, in part, to extend the power of the English Church and Crown, and will examine how this laid the groundwork for the developments in the use of the crusade in its theoretical, symbolic and material forms over the long thirteenth century, contrasting it with the proposal put to Dafydd ap Gruffydd in 1282 by Archbishop Pecham.
