Answer:
In the 1790s, Philadelphia, Pennsylvania, was America's largest city. Between 1790 and 1800, Philadelphia served as the nation's capital. It was the center of wealth and power in the new nation. Prosperous Europeans as well as foreign government officials visited the city and were wined and dined in grand style.
In 1682, William Penn (1644–1718), Pennsylvania's founder, laid out Philadelphia's streets, forming square blocks for houses and buildings. The city was a mix of fine homes and modest houses, wealthy families and working people. It boasted fine taverns (central meeting places that included rooms in which to eat, drink, and spend the night) and nicely appointed boardinghouses, paved streets, many churches, private schools, and a busy waterfront. Philadelphia was also the printing and publishing center of the United States.
