Re-emerging from the disruption caused by the Revolution and the War of 1812, the American whaling industry grew to dominate the seas between 1820 and 1860, only to suffer a severe decline during and after the Civil War. In the following article, Professors Davis, Gallman, and Hutchins examine the hypothesis that the U.S. whaling industry collapsed because the stock of whales was being depleted. After investigating the size of the original whale populations, their breeding habits, and the estimates of whales taken during the nineteenth century, the authors conclude that the overfishing of whales of various species occurred either not at all or too late to have been a contributing factor in America's whaling decline.
