The Erie doctrine, established by Erie Railroad Co. v. Tompkins (1938), mandates that federal courts sitting in diversity jurisdiction (cases with parties from different states) must apply the substantive law of the state where they are located, not federal common law, while still using federal procedural rules. Its main goals are to prevent forum shopping (where parties choose federal court just for favorable law) and ensure fairness by having state law govern state-law claims, whether it's from statutes or state court common law.
