# Ancient History Knowledge Base

## Overview

A structured knowledge base covering ancient history from the earliest civilizations through the fall of the Western Roman Empire @t[..=0476]. The knowledge base spans roughly 3,000 years of human history across Eurasia, North Africa, and the Mediterranean world.

## Scope

This knowledge base documents:

- **Civilizations** — empires, kingdoms, and city-states (Sumer, Akkad, Egypt, Assyria, Persia, Greece, Rome, Carthage, Maurya, Han China, and more)
- **Rulers** — kings, pharaohs, emperors, and generals (Alexander the Great, Hammurabi, Ramesses II, Augustus, Cyrus the Great, and others)
- **Battles** — major military engagements and their strategic significance (Marathon, Thermopylae, Gaugamela, Cannae, Actium, Adrianople)
- **Cities** — major urban centers and archaeological sites (Rome, Athens, Babylon, Alexandria, Ur, Pompeii, Troy)
- **Treaties** — diplomatic agreements and peace settlements (Treaty of Kadesh, Peace of Nicias, Treaty of Apamea)
- **Religions** — belief systems and their development (Greek religion, Egyptian religion, Zoroastrianism, Mesopotamian religion, early Christianity, Roman religion)
- **Technologies** — engineering and material innovations (bronze-working, iron smelting, Roman concrete, aqueducts, roads)
- **Trade routes** — commercial networks and their cultural impact (Silk Road, Incense Route, Amber Road)
- **Legal codes** — foundational law texts (Code of Hammurabi, Code of Ur-Nammu, Twelve Tables)
- **Writing systems** — scripts and literacy (cuneiform, Phoenician alphabet, Egyptian hieroglyphics)
- **Cultural movements** — intellectual and artistic traditions (Greek philosophy, Hellenism)
- **Definitions** — glossary of terms, acronyms, and conventions used throughout

## Conventions

- Dates use BCE/CE notation throughout (not BC/AD)
- Temporal tags use factbase syntax: `@t[=331 BCE]` for exact events, `@t[~2560 BCE]` for approximate dates, `@t[305 BCE..30 BCE]` for ranges
- Approximate dates (common in ancient history) are marked with `~`
- Contested chronologies are noted inline with scholarly variants cited
- Every factual claim cites a source — primary ancient texts or modern archaeological scholarship
- Cross-references link rulers ↔ civilizations ↔ battles ↔ cities where relevant
