# Athens founds Amphipolis as a colonial strongpoint on the Strymon

Date: 437

## The fact

In 437/36 BCE Athens founded Amphipolis on the Strymon under Hagnon. The dated colony is not a generic empire-killing heading and not the later 424 loss to Brasidas. [Pericles](/people/pericles)’s documented role is: Hagnon founded Amphipolis with Athenian and allied settlers. Pericles’ city sent the colony; local Edonians were displaced; he did not uniquely survey the site. Do not twin this with the Delian empire extraction row as a mere adjective. Amphipolis is a named colony. Later editors, printers, and excavators remain named where they appear. Pericles's documented role is: Hagnon founded Amphipolis with Athenian and allied settlers. Pericles’ city sent the colony; local Edonians were displaced; he did not uniquely survey the site.

## Context

Earlier failed attempts at Ennea Hodoi, unnamed settlers, and Edonian land already sit in the file. A colony is not unique authorship of Macedon. Later Philip II is not 437. Named others on the file: Hagnon as founder, unnamed settlers, and local Edonians share the foundation. The public setting is the file around -0437-01-01. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays Athens founds Amphipolis as a colonial strongpoint on the Strymon. The setting of Athens founds Amphipolis as a colonial strongpoint on the Strymon is the public file around -0437-01-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [forced-displacement-scale](/drivers/forced-displacement-scale) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Shared responsibility is part of Athens founds Amphipolis as a colonial strongpoint on the Strymon. Naming Pericles does not delete co-authors, institutions, or later transmitters. The lag from -0437-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

## Significance

Worsening forced-displacement path: a colonial strongpoint on inhabited Thracian land. Complex shared foundation. Welfare reading worsening. The attached mechanism is A dated colonial foundation put a public dispossession-and-timber-gold heading into Thrace. Lag to any modern indicator is not treated as zero. This path is attached because the mechanism is named from this act, not because a driver list needed coverage. The welfare reading on this path is worsening.

The attached driver is forced-displacement-scale. The welfare reading used in this dossier is worsening. That reading is an impact-path choice, not a property stored on the Fact itself.
