 Through the publication of a four-volume extract from his "Allgemeine Geschichte", Rotteck made its contents accessible to the widest possible audience.At the university, where the revitalization of the critical method of historical research posed more earnest requirements to the practitioner than those which Rotteck could fulfill, in 1818 Rotteck exchanged his history pulpit for one in political science and natural law.In this field as well, his inclination to practical achievement felt the need to spread his teaching beyond the walls of his lecture hall, and from 1829 to 1836, he published in four volumes his "Primer of political science and rational law" () which in his mind promised to outdo the almost unprecedented success of his world history in its effect on contemporary public opinion.
