Why Florence killed its entire ruling class – Ada Palmer

Main Ideas / Concepts

• How republics are said to fall: The speaker claims republics typically collapse when power shifts to noble families, especially those dominant in the military class. In this worldview, military commanders are expected to have noble blood, and threats to a republic’s independence often come from the nobility.

• Florence’s response to a near takeover: After a major near-miss in which Florence was nearly taken over, Florence’s leaders decide to remove the nobility as a political threat.

• Violent elimination of the old ruling class: The speaker describes an extreme purge:

  • Most nobles were massacred, with heads cut off.
  • The heads were placed on pikes.
  • Noble houses were burned.
  • Salt was raked into the earth (a symbolic act of destruction/denial).
  • A celebration is described as taking place “on their graves,” framed as a typical practice when removing a class of people.

• Selective accommodation for “acceptable” nobles: Some noble families are allowed to avoid destruction by:

  • Renouncing their nobility
  • Changing their names
  • Declaring themselves commoners
  • Forming a “commoner republic.”

• Who rules instead: The new regime’s power base is described as merchant-guild owners rather than artisans/workers:

  • The “merchant guild” member is framed as the owner of productive businesses/invested capital (e.g., workshops, firms, warehouses, architectural/sculpture firms), not the laborers.

• Diplomatic legitimacy problem: In surrounding societies (where rulers and envoys are assumed noble-blooded), Florence’s leaders are treated as low-status:

  • The speaker claims ambassadors from Florence would be taken seriously only if they had noble blood, implying Florence’s ruling class lacks the expected pedigree.

• Military/policing workaround: Because Florence no longer has nobles internally:

  • It supposedly cannot run its own armies or police effectively (in the speaker’s framing, because people would not obey orders from non-noble commanders).
  • Therefore Florence must hire a nobleman to enforce order “in the name of the Holy Roman Emperor.”
  • This noble authority is portrayed as temporary, heavily controlled, and removed permanently.

Methods / “Instructions” Described (as a System)

A) Hiring and controlling a noble chief of police / enforcement

• Bring in a nobleman to Florence to act as chief of police (and enforce laws on behalf of the Holy Roman Emperor).
• The nobleman:
  • Lives in the palace, described as also functioning as a prison.
  • Arrests people who enforce or uphold the law.

Compensation and removal:

• Florence pays him handsomely at the end of the year.
• The city escorts him out to the gates.
• He is banished for life under penalty of death to prevent return and power reassertion.

B) Lottery-based power sharing to “prevent tyranny”

• Select eligible candidates among merchant-guild members based on fitness:

  • Not ill or dying
  • Not insane
  • Not so deeply in debt that creditors/manipulators can influence them

• Random selection / lottery:

  • Put names in a bag.
  • Choose nine men at random.

• Governance structure:

  • The nine chosen rule from a locked/towered setting (kept in a tower to reduce bribery/kidnapping).
  • They govern for about 2–3 months.

• Rotation:

  • After their term, they are thanked and escorted out.
  • Nine new randomly selected men take over.

• Designed-in “tyrant-proof” governance logic:

  • The speaker claims the design requires consensus (not even simple majority) among the randomly selected group.
  • The aim is to make it hard for any one person or faction to seize control.
