Zagorin then produced a series of monographs on particular participants in the troubles of 17th-century England, first "Milton: Aristocrat & Rebel" (1992), looking at the political beliefs of the poet John Milton. Next was "Francis Bacon" (1999), about the English philosopher and courtier, Sir Francis Bacon, that explored the dissonance between the soaring ideals of Bacon's philosophical ambitions and his life as courtier, politician, and lawyer serving in government. A final monograph on Thomas Hobbes, "Hobbes and the Law of Nature", was published posthumously in 2009.
