The campaign enabled the rebel militia to reclaim most ...

Turnpikes
From their earliest introduction in Pennsylvania in the late eighteenth century to their modern incarnations as high-speed highways, turnpikes have expanded Philadelphia’s reach to points west and linked the region with other commercial centers and suburbs of the eastern seaboard.

Twin Houses
Semidetached or "twin" houses, sometimes referred to as "doubles," began appearing in the Philadelphia region in the mid-nineteenth century and were constructed in significant numbers until World War II, after which the GI Bill and spacious suburban tracts spurred on construction of detached houses.

United States Colored Troops
During the American Civil War (1861-65), Philadelphians raised eleven regiments of the United States Colored Troops (USCT).

Regarded as the largest playable instrument in the world, the Wanamaker Grand Court Organ remained a highlight of the Center ...
War in Afghanistan
