  Beginning in 1969, a spate of short articles were published on coercion. The earliest of significance was Robert Nozick's “Coercion.” It was followed shortly by a collection of essays by political philosophers published in a volume of the Nomos series, focused on coercion (Pennock and Chapman 1972). These articles were in turn followed by an outpouring of responses and original discussions of coercion that continued throughout the 1970s and 80s. The influence of these early discussions of coercion remains strong. So it is useful to begin thinking about contemporary treatments of coercion by looking at how these early articles framed the topic.
