Pennsylvania, officially the Commonwealth of Pennsylvania, one of the Middle Atlantic states, and
one of the 13 original states of the United States. It entered the Union on December 12, 1787, making it second after Delaware. Pennsylvania means "Penn's woodland." It was named in honor of Admiral William
Penn, whose son, William Penn, founded the colony as a haven for members of the Society of Friends, or Quakers, and other
religious minorities in 1682.
