He began to study theology at the University of Copenhagen and later taught himself law, history and language. He was not particularly interested in theology as a career, settling for an "attestats" (similar to a Bachelor's degree today), which gave him the right to work as a priest; he did not attempt a baccalaureus, magister or doctorate in the subject, nor did he follow a career as a theology professor, priest, or bishop. In Holberg's youth, it was common to study theology and specialize according to one's degree, for example in Greek, Latin, philosophy or history. For the purpose of becoming a lawyer, it was normal to study abroad. In 1736 the Danish Lawyer degree was established at the University of Copenhagen, a degree which continued to be granted for 200 years, and for which Holberg's writings remained common reading material throughout this time. Holberg was formally appointed assistant professor after having first worked as one without pay. He had to accept the first available position, which was teaching metaphysics. Later, he became a professor and taught rhetoric and Latin. Finally, he was given a professorship in the subject which he prized most and was most productive in, history.
