The Battle of Gaugamela (1 October 331 BCE) was the decisive battle in which Alexander the Great defeated the Persian King Darius III, effectively ending the Achaemenid Persian Empire. @t[=331 BCE] The date is confirmed by Babylonian astronomical diaries. [^3]
## Key Facts
- Date: 1 October 331 BCE @t[=331 BCE]

- Darius leveled the battlefield to give his scythed chariots and cavalry a decisive advantage; some Persian forces were equipped with Macedonian-style sarissae [^3]

- [x]`@q[ambiguous]` Line 13: "Commanders: Alexander the Great vs. Darius III" - what does "III" mean in this context?
> III is the regnal number — Darius III Codomannus was the third Persian king named Darius. Standard historical convention.
- [x]`@q[ambiguous]` Line 25: "Darius III was later murdered by his own satrap Bessus (330 BCE)" - what does "III" mean in this context?
> Same as above — III is the regnal number for Darius III. Standard convention.
- [x]`@q[stale]` Line 26: "Marked the end of the Achaemenid dynasty after ~220 years [^2]" - Heckel source from 2008 may be outdated, is this still accurate?
> Heckel (2008) remains a standard reference. The end of the Achaemenid dynasty in 330 BCE is undisputed historical fact. Still accurate.
