The heartfelt words of Prioress Barbara Wiseman and the Bridgettine sisters in Lisbon to the Spanish Infanta might have been written by any of the exiled English nuns during the seventeenth century. As members of a religious minority which was not permitted officially to practise its faith, hundreds of women left their homeland to join expatriate religious communities abroad. The exodus began in the aftermath of Henry VIII's dissolution of the monasteries when groups of Bridgettines, Dominicans, Poor Clares and possibly nuns of other orders travelled abroad to continue their pious vocation in continental cloisters. Likewise, individuals determined to maintain their vows settled in foreign houses. The numbers of English Catholics desiring a monastic life for themselves or their female kin were so high that by the late sixteenth century the first post-Reformation abbey was established for Benedictines in Brussels. An English Poor Clare convent was founded at St Omer in 1608, and in 1609 the English women resident in the Flemish cloister of Augustinian canonesses in Louvain departed to form their own community. By the end of the seventeenth century, there were twenty-two contemplative English convents which had survived the vicissitudes of exile and poverty described by the Bridgettine nuns eighty years earlier. Twenty-one were located within a relatively small part of north-western Europe, in the Low Countries and in France, while the Bridgettines resided to the south in Lisbon.

The history of the English Bridgettines is thus closely connected with that of the other expatriate cloisters, yet it is also distinct. Unlike the other post-Reformation religious houses which had tenuous links with the pre-dissolution monastic orders, the Bridgettine nuns could claim direct continuity with pre-Reformation Syon Abbey in Isleworth.
