# Spartan dual kingship sends one king to a blocking pass

Date: 480

## The fact

Oligarchic-military kingship as later told is a resilience-cost of medium confidence, not a modern dictatorship file. The dated public instrument is stored under 1920-03-01. [Leonidas I](/people/leonidas-i) did not operate this later page as a civil-registry autograph.

It is one event.

## Context

Shared institutions, unnamed crews, and later editors remain in the record and do not erase a documented heading.

Leonidas I Shared work with other named actors remains in the record.

Leonidas I’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

The surviving file is narrow: [Herodotus](/people/herodotus) as later English, later lives, a modern monument, and encyclopedia pages.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Britannica — Leonidas I and Cambridge Companion to Archaic Greece independently describe this instrument.

Official or archival record: Britannica — Leonidas I (https://www.britannica.com/biography/Leonidas-king-of-Sparta; Encyclopaedia Britannica).

## Significance

Oligarchic-military kingship as later told is a resilience-cost of medium confidence, not a modern dictatorship file.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Leonidas I.

They are not a public rating.

The driver `democratic-resilience` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Leonidas I did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct.
