The location which is now "Crawford Square" was an elevated slope about one mile (1.6 km) east of the original city of Pittsburgh. In 1800, only 1565 people lived in Pittsburgh. Separate annexations occurred in 1837, 1847, 1868, 1874, and 1906. In 1900, 321,616 residents were counted, including a group of Jews who had constructed the first synagogue (now demolished and replaced) near Elm Street. At that time, a local term for the large general area was "Jews Hill." Despite that name, other sorts of people lived there, including Italians, African Americans, Russians, and more.
