These items cover four different periods with regard to Bradlaugh: from birth until he left the army, Bradlaugh's political career prior to Parliament, his parliamentary career, and from his deathbed to securing his legacy. The first period, running from 1833 until 1859 includes his birth certificate and papers prior to 1849; these papers are followed by records relating to his short stay in the military. Items covering Bradlaugh's political career, prior to Election to Parliament, shed new light on the Devonport affair, his membership of the Freemasons' Lodge which was expelled by the Grand Lodge of Ireland and England for its commitment to secularism, and his support for Prince Napoleon Joseph Bonaparte (b.1822, d.1891). The first part of Bradlaugh's correspondence and papers during his time in Parliament focusses upon the six legal cases which he was fighting as either the plaintiff or the defendant; the latter part focusses more on Bradlaugh's parliamentary work with particular regard to India. The bulk of the content from 1890 until 1899 focusses upon Bradlaugh's death and the reaction to it. Correspondence and papers from 1900 reveal the depth of Hypatia Bonner (née Bradlaugh)'s determination to protect her father's legacy and correct any reports of him she saw as inaccurate.
