Two Factors Driving Greek & Phoenician Colonization (8th–6th C. BCE)

1. Population Pressure & Land Hunger

• Greece: Mountainous terrain → limited arable land. Population growth (800–500 BCE) outstripped capacity. Stasis (civil strife) between landless and aristocrats. Colonies = safety valve (e.g., Cyrene, Syracuse, Massalia).
• Phoenicia (Tyre, Sidon, Byblos): Narrow coastal strip backed by mountains. High urban density. Trade profits funded colonization but land scarcity pushed surplus population westward.

2. Trade & Resource Access

• Greece: Needed metals (tin, copper, silver, iron), grain (Black Sea), timber, slaves. Colonies secured supply chains: Massalia (tin route), Olbia (grain), Thasos (gold/silver).
• Phoenicia: Masters of maritime trade. Colonies as commercial waystations — Cadiz (silver), Carthage (hub), Lixus (fish/dye), Mogador (purple dye). Monopoly on Mediterranean luxury goods (purple, glass, cedar).

Synergy

Overpopulation created migrants; trade networks provided routes, knowledge, and economic rationale. City-states (polis) often sponsored colonies (apoikia) with oaths, sacred fire, and political ties to mother city (metropolis).
