The 14th amendment was passed in 1868, to settle important matters arising from the civil war, including how we define equality before the law. Ever since, it has served as the foundation for one landmark supreme court decision after another, from Brown v Board of Education (1954), which banned segregation in public schools, to Obergefell v Hodges (2015), which legalized gay marriage.
In recent times, a little-known feature has come into sharp focus. Six days after the January 6 Capitol attack, Eric Foner, a historian of the US civil war and the Reconstruction era, argued that section 3 of the amendment forbids an “officer of the United States” from holding office if he or she has sworn an oath to the constitution, then participated in an “insurrection or rebellion”.
