John Ryan Fischer‘s book Cattle Colonialism: An Environmental History of the Conquest of California and Hawai’i (University of North Carolina Press, 2015) is a fascinating look at how a common animal—the cow—changed the landscapes, economies and peoples of both California and Hawai’i, and linked them together in unexpected ways, in the late 18th and early 19th centuries. After the introduction of cattle into each of these societies by Europeans, not only did the cows bring ecological change, but they fundamentally altered how people lived, worked, earned their living and interacted with the world at large. As California’s and Hawai’i’s economies became increasingly focused on cattle, especially the hide and tallow industries in the 1820s and 30s, the changes both in the land and the people who worked it paved the way for broader colonial projects both by European countries and eventually the United States.
