A federal system of government is a system in which power is shared between a central government and regional governments (e.g., states or provinces). It has several advantages, including:

1. Economies of Scale – Federalism allows regions to pool resources for large-scale projects like infrastructure, security, and economic planning, reducing costs and increasing efficiency.
2. Uniform Development – It ensures that all regions receive attention in national development policies, reducing disparities between wealthy and less developed areas.
3. Political Unity – Federalism helps maintain national unity by giving diverse groups a say in governance while preventing excessive centralization of power.
