Exclusion Crisis
In the late 1660s, Bohun became associated with William Sancroft, Samuel Parker and Leoline Jenkins, in a group of High Church proto-Tory thinkers. He began to write against the Whigs after the Exclusion Crisis of the 1680s. He attacked Whig theories and in particular Algernon Sidney in his "Defence of Sir Robert Filmer" (1684). Sancroft asked Bohun to edit Robert Filmer’s works, for an edition of 1685, and its preface Bohun attacked James Tyrrell.
