 Barnard 1965 (chs. 3–5 cover Herder’s political thought very well); Beiser 1992 (ch. 8 on Herder’s political philosophy is excellent); Berlin 1976; Bernasconi 1995; Ergang 1931 (helpful on Herder’s political thought and on his intellectual influence, but marred by a false assimilation of Herder’s nationalism to later German nationalism, and by an unduly warm assessment of such a position); Forster 2010 (ch. 7), 2017a, 2018 (ch. 9); Sikka 2011.
