CEVAP:

 A confederal system is one where loose states agree to abide by the dictates of a powerful central government.  Nations that constitute the confederacy are not obliged to follow the lead of a weak central government. Examples of confederacies include the former Soviet Union, the Confederate States of the United States (1861-1865), and Switzerland’s Canton system. A confederation can be described as a union of sovereign states whereby each constituent party maintains its autonomy. Another example of a confederation is the German Confederation.
