From ancient trials and imperial decrees to school board showdowns and modern firewalls, this episode maps how power tries to control ideas. We trace the recurring playbook of censorship—and what actually stops it.

Key takeaways

• Censorship evolves with technology but keeps the same aims: consolidate power, narrow debate, and make dissent illegible.
• “Protective” language (morals, children, national security) is the most common pretext.
• The antidote is persistent transparency: read the banned books, show up locally, fund independent journalism, and document removals and edits.
