Euler Historica

Certainly, Euler's works were not written in an historical vacuum. They were tempered by the political and social events of the time, advances in the scientific community, availability of documents, technological progress, and so on. While it is impossible to encapsulate the entire 18th century in one source, a number of brief summaries are given below.
