I’ve been doing background research for my new project on geography and Asian American history, which I’m tentatively calling Barred Zones after the “Asiatic Barred Zone” established in 1917. Part of the article/chapter I’m writing involves systems of longitude and latitude—which fascinates my inner geek. While most people associate these systems with geography and think of them as, in a sense, “natural” because they locate places on the Earth, they are actually “social,” produced by people and institutions within specific historical contexts and circumstances, including politics, local, regional, national and international. A nice example demonstrating this point is the Washington meridian and its use in defining state and territorial borders within the United States in the late 19th century.
