The Introduction is in three parts. The first introduces the object of study and the sources and methodology used to study it and puts the topic in its historiographical context. The second locates it in terms of the religio-political developments of the period between the 1590s and the 1620s. The third addresses the immediate political and polemical circumstances in which Laudianism rose to prominence and then power in the mid- to late 1620s, and then identifies the 1630 edition of Lancelot Andrewes’ sermons as the movement’s key foundational text or mission statement.
