Prior to the nineteenth century, algebra meant the study of the solution of polynomial equations. By the twentieth century algebra came to encompass the study of abstract, axiomatic systems such as groups, rings, and fields. This presentation provides an account of the intellectual lineage behind many of the basic concepts, results, and theories of abstract algebra.

This book charts the contributions made to the development of the late medieval English economy by enterprise, money, and credit in a period which saw its major export trade in wool, which earned most of its money-supply, suffer from prolonged periods of warfare, high taxation, adverse weather, and mortality of sheep. Consequently, the economy suffered from severe shortages of coin, as well as from internal political conflicts, before the plague of 1348-9 halved the population. The book examines from the Statute Merchant certificates of debt, the extent to which credit, which normally reflects economic activity, was affected by these events, and the extent to which London, and the leading counties were affected differently by them. The analysis covers the entire kingdom, decade by decade, and thereby contributes to the controversy whether over-population or shortage of coin most inhibited its development.
