An economic history of the last half of the 18th century demonstrating the symbiotic economic relationship between Russia and great Britain during the period. Kaplan (history, U. of Indiana) presents new archival documents, interpreting a mountain of data from customs and commercial manuscripts that indicate Russia contributed to Britain's industrial revolution and imperial strategic military and political power by its supply of manufactured and natural resources. The research evaluation includes commercial policy prior to Catherine II, Russian commodity exports, the influence of war and contraband, and both the balance of trade and culture between the two countries. Includes tables and graphs. Annotation c. by Book News, Inc., Portland, Or.
