Although the courts of appeals are frequently called "circuit courts", they should not be confused with the former United States circuit courts, which were active from 1789 to 1911, during the time when long-distance transportation was much less available, and which were primarily first-level federal trial courts that moved periodically from place to place in "circuits" in order to serve the dispersed population in towns and the smaller cities that existed then. The current "courts of appeals" system was established in the Judiciary Act of 1891, also known as the Evarts Act.
