What does a constitution do?
A constitution sets out how a government works and what citizens may expect from it.
- Government: it states the work and functions of the government or organisation.
- Officials: it states the functions of the officials of the government.

What is constitutionalism?
Constitutionalism is the practice of governing according to the constitution, so that the powers of government are limited by law.
- Supremacy of the constitution: no person or office is above the constitution.
- Rule of law: everyone, including leaders, is equal before the law.
- Limited government: the powers of rulers are defined and restricted.
- Separation of powers: the executive, legislature and judiciary have separate roles.
- Fundamental human rights: the rights of citizens are protected.
- Independent judiciary: courts can interpret the constitution without interference.
- Free and fair elections: leaders are chosen and changed peacefully at regular intervals.
- Accountability: office holders answer to the people for their actions.

| Nature | A document or set of rules | An idea and a way of governing |
| Focus | What the rules are | Whether the rules are followed and power is limited |

What are the features of a constitution?
The features of a constitution are the standard parts found in most constitutions.

What are the types of constitution?
Constitutions are classified in three ways: by form (written and unwritten), by ease of amendment (rigid and flexible), and by distribution of power (federal, unitary and confederal).
What is a written constitution?
A written constitution is one in which the fundamental laws of a country are written and codified in a single document.
- Examples: Nigeria, USA, India, France, Canada, Sierra Leone and the Gambia.
Features of a written constitution

- Amendable: it can be changed when the need arises.
- Minority protection: the interests of minorities are protected.
- Stability: it defines the powers of government and how to use them, so it reduces conflict.
Disadvantages of a written constitution
- Rigidity: most written constitutions are rigid, which creates problems with amendment.
- Disaffection: it may cause discontent if it does not favour some sections of the country.
- Out of date: unless it is amended often, it will not meet present and future needs.

- Slow: amendment takes a long time.
- Costly: the amendment process may be expensive.
What is an unwritten constitution?
An unwritten constitution is one whose fundamental laws are not codified in a single document, although some parts may be written down.
