Keystone State (Pennsylvania)

The "Keystone State" is a nickname for Pennsylvania, derived from its historical importance in the founding of the United States. Pennsylvania was considered the "keystone" because it held a central position among the original colonies and played a vital role in shaping the nation's development. The term also reflects how the state serves as a crucial support element, much like a keystone in an arch. Today, Pennsylvania is known for its diverse economy, rich history, and cultural contributions, making it an essential part of the American story.
