Confederate naval building during the US Civil War (1861–1865) was a form of “self-strengthening” that had much in common with similar efforts across the Pacific World in the 1860s and 1870s. To overcome structural limitations (a lack of industrial capacity or existing warships), Confederate navy builders relied on foreign acquisitions and local innovations such as the torpedo to compete with the materially superior United States. The US Civil War was, in this sense, a vast practical experiment for small or industrially weak states confronting North Atlantic power. Beginning in the 1860s, the template set by the Confederacy – local adaptation with cheap asymmetric weapons and the overseas acquisition of qualitatively advanced systems – found numerous adopters in Pacific newly made navies. Reciprocally, many industrial producers in Europe were stimulated by demand from the Confederacy to produce novel weapons for Pacific states.
