The death of Justice Ruth Bader Ginsburg concludes an era of faith in courts as partners in the fight for progress and equality.

The death of Justice Ruth Bader Ginsburg ends an incredible legal career, one that advanced gender equality and inspired millions. RBG, as she became popularly known, was, like Thurgood Marshall before her, one of the handful of justices who, through their work as lawyers fighting for justice, can truly be said to have earned their spot on the judicial throne.

This faith is more recent than many people recognize. A century ago, the biggest critics of the federal judiciary were on the left, and for good reason. For most of its history, the Supreme Court was the most conservative of the three branches of government, consistently blocking, or at least delaying, efforts at social, political, and economic reform. From Dred Scott and Plessy v. Ferguson, in which the Court upheld the subordination of racial minorities, to Lochner, which denied the government the ability to regulate much of economic life, the Court epitomized what William F. Buckley would later identify as the conservative credo: the impulse to “stand athwart history, yelling Stop.” By the Progressive Era and the Great Depression, it was widely held that the Supreme Court could only hinder, not help, the cause of reform.
