Final answer:
Confederal systems are uncommon today due to a lack of unity and coordination among member states, and the rise of federal systems. One example is the Articles of Confederation in the United States.
Step-by-step explanation:
Confederal systems are not common today primarily because they often suffer from a lack of unity and coordination among the member states. In a confederal system, power is decentralized and held by individual states, with only limited authority given to a central government. This can lead to disagreements and difficulties in making collective decisions, which can hinder the effectiveness and overall functioning of the system.
One example of a confederal system is the Articles of Confederation in the United States. This system proved to be too weak and ineffective, leading to the adoption of a federal system with a stronger central government.
Additionally, as societies and economies become more complex and interconnected, there is a growing recognition of the need for strong central authority and coordination in decision-making. This has led to the rise of federal systems, where power is shared between central and regional governments, rather than confederal systems.
