History and development

The county takes its name from the Penobscot people, an Indigenous nation whose homeland includes the river basin. Euro-American settlement intensified in the 18th and early 19th centuries. Bangor grew in the 19th century as a lumber and shipbuilding center, its economy later diversifying while still linked to timber and paper manufacturing.

Today the county's economy blends higher education, health care, retail, government services and natural-resource industries. The University of Maine, founded in the 19th century and located in Orono, is an important research and employment anchor for the region.
