Context: <response>: Until recently, for absence of agreement on top clear and precise definition, people bin dey think say federalism mean 'division of power between two levels of government'. But new research don show say this no dey correct, as dividing power - when you understand am well well as the final and absolute source of political authority for inside one political community - no fit happen. The time wey United States enter Civil War for mid-nineteenth century, because of wahala about competences wey never allocate concerning slavery and finally the right to secede, show this one. One level of government fit get power to decide these kind matters, but e no fit be both at the same time. So, dem dey suggest now say federalism dey more better defined as 'division of powers wey dey flow from sovereignty between two levels of government'. Wetin make this concept different from other political forms wey get different levels na the equality of standing between the two levels of government wey dey established. This clear definition don open way to identify two different federal forms, where before na only one dey known, based on whether sovereignty dey for the whole (for one people) or for the parts (for many peoples): the federal state (or federation) and the federal union of states (or federal union), respectively. Examples of federal state include United States, Germany, Canada, Switzerland, Australia and India. The main example of federal union of states na the European Union.
