Preservation of interests

Nevertheless, a full incorporating union may preserve the laws and institutions of the former states, as happened in the creating of the United Kingdom. This may be simply a matter of practice or to comply with a guarantee given in the terms of the union. These guarantees may be to ensure the success of a proposed union, or in the least to prevent continuing resistance, as occurred in the union of

, though they were continued as a matter of practice. The informal recognition of such interests represents the different circumstances of the two Unions, the small base of institutional power in Ireland at the time (those who were the beneficiaries of the Protestant Ascendancy) had faced a revolution in the Irish Rebellion of 1798, and as a result there was an institutional drive toward unification, limiting the Irish negotiating power. However, informal guarantees were given to preclude the possibility of further Irish unrest in the period following the French Revolution of 1789 and the 1798 rebellion. These types of informal arrangements are more susceptible to changes; for example,

Federal annexation occurs when a unitary state becomes a federated unit of another existing state, the former continuing its legal existence. The new federated state thus ceases to be a state in international law but retains its legal existence in domestic law, subsidiary to the federal authority.

, he says:
Two kinds of union have been proposed – federal and legislative. By the first, the separate legislature of each province would be preserved in its present form and retain almost all its present attributes of internal legislation, the federal legislature exercising no power save in those matters which may have been expressly ceded to it by the constituent provinces. A legislative union would imply a complete incorporation of the provinces included in it under one legislature, exercising universal and sole legislative authority over all of them in exactly the same manner as the Parliament legislates alone for the whole of the British Isles.
However, unification is not merely voluntary. To meet this requirement, we need to have a balance of power between the two or more states, which can create an equal monetary, economic, social and cultural environment. We need also to take in account that those states eligible to unify must agree to a transition from anarchy, where there is no sovereignty above the state level, to hierarchy. States can decide to enter a voluntary union as a solution for existing problems and to face possible threats, such as environmental threats for instance. The task of triggering a political crisis and to get the attention of the citizens toward the unification's necessity is in the hands of the elites. Despite it being quite rare, in some cases it works (see Switzerland and the United States unification), while in most of the cases it turns to be a failure or leads to a forced unification (Italy, URSS) where the unified states are deeply unequal. From a realist perspective, small states can unify in order to face strong states or to conquer weak ones. One of the reasons to seek unification to a stronger state besides a common threat can be a situation of negligence or ignorance on behalf of the weak state which is, to simplify it, desperate and almost derelict.

, unions were motivated by security threats. According to Ryan Griffiths, all instances of mutually willful unification from 1816 onwards were between states that spoke the same languages.
