The Supreme Court’s interest in personal jurisdiction has waxed and waned since the iconic International Shoe Co. v. Washington, cycling between thirteen-year spurts of jurisdictional pronouncements followed by two decades of silence. From International Shoe in 1945 to Hanson v. Denckla in 1958, the Supreme Court issued six personal jurisdiction decisions that developed the minimum contacts analysis under the Due Process Clause. The Court then took an almost twenty-year break before returning to the adjudicative jurisdictional fray in another thirteen-year stint from 1977 to 1990, this time resolving ten personal jurisdiction cases. After failing to coalesce around a majority opinion in its last two attempts, the Supreme Court withdrew again from the field, leaving the lower federal and state courts to their own devices for slightly more than twenty years, until the Roberts Court re-engaged with personal jurisdiction a decade ago.
