Jacques Nicolas Augustin Thierry (10 May 1795 – 22 May 1856; also known as Augustin Thierry) was a French historian. Although originally a follower of Henri de Saint-Simon, he later developed his own approach to history. A committed liberal, his approach to history often introduced a romantic interpretation, although he did engage in research of primary sources. He nevertheless was recognised as a significant historian of the evolution of communal governance. Source: Wikipedia (en)
