The United States circuit courts were the intermediate level courts of the United States federal court system from 1789 until 1912. They were established by the Judiciary Act of 1789, and had trial court jurisdiction over civil suits of diversity jurisdiction and major federal crimes. They also had appellate jurisdiction over the United States district courts. The Judiciary Act of 1891 (, also known as the Evarts Act) transferred their appellate jurisdiction to the newly created United States circuit courts of appeals, which are now known as the United States courts of appeals. On January 1, 1912, the effective date of the Judicial Code of 1911, the circuit courts were abolished, with their remaining trial court jurisdiction transferred to the U.S. district courts. During the 100 years that the Justices of the U.S. Supreme Court "rode circuit", many justices complained about the effort required. Riding circuit took a great deal of time (about half of the year) and was both physically demanding and dangerous. However, "members of Congress held firm to the belief that circuit riding benefited the justices and the populace, and they turned a deaf ear to the corps of justices that desired to abolish the practice." The Judiciary Act of 1869 established a separate circuit court (and allowed the hiring of judges specifically to handle the cases) but the act required that Supreme Court justices had to ride circuit once every two years. However, this came to a final end in 1891 when the Circuit Courts of Appeals Act was passed. Organization Although the federal judicial districts were grouped into circuits, the circuit courts convened separately in each district and were designated by the name of the district (for example, the "U.S. Circuit Court for the District of Massachusetts"), not by the name or number of the circuit. The designation of circuits served only for the purpose of designating the districts in which a particular Supreme Court Justice, and later a circuit judge, would sit on the circuit court. The circuit court districts were usually, but not always, the same as the districts established for the district courts. Congress had borrowed the general idea of circuit courts from England, but at their creation, the new United States circuit courts were "a unique institution, whose composition and jurisdiction did not resemble any prior court in England or America." Each circuit court was composed initially of two Supreme Court
