This book is a modern and accessible edition of a manuscript journal kept by Thomas Juxon, a Puritan Londoner, who produced and traded in sugar. Juxon’s journal focuses on public affairs and political and military developments during years of intense political manoeuvring, from the latter stages of the civil war and post-war attempts to reach a settlement with the king, to the crisis of the summer of 1647 and the army’s occupation of London. It sheds fresh light on the emergence and course of party and factional politics both within Parliament and in the City of London, and reveals the thoughts and convictions of an informed Londoner who was a committed participant in these events. Keith Lindley and David Scott’s substantial introduction provides a full account of Juxon’s life, describes the format of the journal and discusses its historical value, while the text is supported by full scholarly apparatus.
