The basic unit of every political organization in the Igbo pre-colonial era was the

Analyze the question: It asks about the basic unit of political organization in pre-colonial Igbo society. Igbo society was largely stateless (acephalous) and decentralized, with no central king in most areas.

Explain the concept: Traditional Igbo political structure was built up from small groups into larger ones:

1. Family (nuclear/extended family, headed by the Okpara or eldest male): the smallest and most basic unit. The head settled family disputes and represented the family at higher levels.
2. Kindred/lineage (Umunna): a group of related families.
3. Village: made up of several kindreds, run by a village council or assembly of elders (Ohanaeze/Ndichie).
4. Village group/town: a federation of villages.

Other institutions cut across this structure. Age-grades carried out public works, defense, and law enforcement. Secret societies, the Ozo title holders, and oracles such as Aro Chukwu also played roles. However, they were functional institutions, not the foundational unit of organization.

Evaluate the options:

• A. ala: refers to land or the earth goddess (Ala/Ani), a religious and moral authority. It is not a political unit.
• B. family: the foundation on which the kindred, village, and village group were built. ✔
• C. age-grade: important for executing decisions, but it is not the basic unit.
• D. village council: a higher-level body, composed of family and lineage heads.

Exam tip: Remember the Igbo ladder as Family → Kindred → Village → Village group. When a question says "basic unit," pick the smallest building block. For Igbo, that is the family.
