In addition, modern historians such as Linda Colley and anthropologists such as Pauline Turner Strong have also found the North American narratives useful in analyzing how the colonists or settlers constructed the "other". They also assess these works for what the narratives reveal about the settlers' sense of themselves and their culture, and the experience of crossing the line to another. Colley has studied the long history of English captivity among other cultures, both the Barbary pirate captives who preceded those in North America, and British captives in cultures such as India or East Asia, which began after the early North American experience.
