On 26 March 1678 he was sent for on the charge of having written a pamphlet called A Letter from a Jesuit in Paris, showing the most efficient way to ruin the Government and the Protestant Religion, in which the names of various members of parliament were introduced.
[2] Nalson then published several other pamphlets, undertook to make a collection of documents in answer to John Rushworth (1682), and printed the Trial of Charles I (1684), prefixing to his historical works long polemical attacks on the whigs.
He begged William Sancroft for preferment; he asked on 21 July 1680 for the deanery of Worcester, on 14 August 1680 for the mastership of Trinity College, Cambridge, and to be given a prebend either at Westminster or Ely.
[2] Nalson's major work is the Impartial Collection of the Great Affairs of State, from the beginning of the Scotch Rebellion in the year 1639 to the murder of King Charles I.
Some documents from Nalson's collection were printed by Zachary Grey in his answer to Daniel Neal's History of the Puritans (1737-9), and others by Francis Peck in his Desiderata Curiosa (1735).
[2] Nalson is notable for making the claim that Cardinal Richelieu of France was involved in secretly stoking the initial stages of the Irish Rebellion of 1641 and the unrest of Scottish Covenanters in the Bishops' Wars during the reign of Charles I of England.
