The Taney Court refers to the Supreme Court of the United States from 1836 to 1864, when Roger Taney served as the fifth Chief Justice of the United States. Taney succeeded John Marshall as Chief Justice after Marshall's death in 1835. Taney served as Chief Justice until his death in 1864, at which point Salmon P. Chase took office. Taney had been an important member of Andrew Jackson's administration, an advocate of Jacksonian democracy, and had played a major role in the Bank War, during which Taney wrote a memo questioning the Supreme Court's power of judicial review. However, the Taney Court did not strongly break from the decisions and precedents of the Marshall Court, as it continued to uphold a strong federal government with an independent judiciary. Most of the Taney Court's holdings are overshadowed by the decision in Dred Scott v. Sandford, in which the court ruled that African-Americans could not be citizens. However, the Taney Court's decisions regarding economic issues and separation of powers set important precedents, and the Taney Court has been lauded for its ability to adapt regulatory law to a country undergoing remarkable technological and economic progress.

Roger Brooke Taney was an American lawyer and politician who served as the fifth chief justice of the United States, holding that office from 1836 until his death in 1864. Taney infamously delivered the majority opinion in Dred Scott v. Sandford (1857), ruling that African Americans could not be considered U.S. citizens and that Congress could not prohibit slavery in the U.S. territories. Prior to joining the U.S. Supreme Court, Taney served as the U.S. attorney general and U.S. secretary of the treasury under President Andrew Jackson. He was the first Catholic to serve on the Supreme Court.
