John Marshall (September 24, 1755 – July 6, 1835) was the fourth Chief Justice of the Supreme Court of the United States (1801–1835). His court opinions helped lay the basis for United States constitutional law and many say made the Supreme Court of the United States a coequal branch of government along with the legislative and executive branches. Previously, Marshall had been a leader of the Federalist Party in Virginia and served in the United States House of Representatives from 1799 to 1800. He was Secretary of State under President John Adams from 1800 to 1801
