Centralisation in the context of "Power structure"

A palace economy or redistribution economy is a system of economic organization in which a substantial share of the wealth flows into the control of a centralized administration, the palace, and out from there to the general population. In turn the population may be allowed its own sources of income but relies heavily on the wealth distributed by the palace. It was traditionally justified on the principle that the palace was most capable of distributing wealth efficiently for the benefit of society. The temple economy (or temple-state economy) is a similar concept.

The concept of economic distribution is at least as old as the advent of the pharaohs. Anthropologists have noted many such systems, from those of tribesmen engaged in common subsistence economies of various sorts to complex civilizations, such as that of the Inca Empire, which assigned segments of the economy to specific villages. The essence of the idea is that a central administration plans production, assigns elements of the population to carry it out, collects the goods and services thus created, and redistributes them to the producers.

In the Soviet Union, a Union Republic (Russian: Сою́зная Респу́блика, romanized: Soyúznaya Respúblika) or unofficially a Republic of the USSR was a constituent federated political entity with a system of government called a Soviet republic, which was officially defined in the 1977 constitution as "a sovereign Soviet socialist state which has united with the other Soviet republics to form the Union of Soviet Socialist Republics" and whose sovereignty is limited by membership in the Union. As a result of its status as a sovereign state, the Union Republic de jure had the right to enter into relations with foreign states, conclude treaties with them and exchange diplomatic and consular representatives and participate in the activities of international organizations (including membership in international organizations). The Union Republics were perceived as national-based administrative units of the Union of Soviet Socialist Republics (USSR).

The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russian SFSR (RSFSR), Transcaucasian Federation, and Ukraine, by which they became its constituent republics of the Union of Soviet Socialist Republics (Soviet Union). For most of its history, the USSR was a one-party state led by the Communist Party of the Soviet Union. Key functions of the USSR were highly centralized in Moscow until its final years, despite its nominal structure as a federation of republics; the light decentralization reforms during the era of perestroika (reconstruction) and glasnost (voice-ness, as in freedom of speech) conducted by Mikhail Gorbachev as part of the Helsinki Accords are cited as one of the factors which led to the dissolution of the USSR in 1991 as a result of the Cold War and the creation of the Commonwealth of Independent States.

European integration is the process of political, legal, social, regional and economic integration of states wholly or partially in Europe, or nearby. European integration has primarily but not exclusively come about through the European Union and its policies, and can include cultural assimilation and centralisation.

The history of European integration is marked by the Roman Empire's consolidation of European and Mediterranean territories, which set a precedent for the notion of a unified Europe. This idea was echoed through attempts at unity, such as the Holy Roman Empire, the Hanseatic League, and the Napoleonic Empire. The devastation of World War I reignited the concept of a unified Europe, leading to the establishment of international organizations aimed at political coordination across Europe. The interwar period saw politicians such as Richard von Coudenhove-Kalergi and Aristide Briand advocating for European unity, albeit with differing visions.

The Declaration and Treaty on the Formation of the Union of Soviet Socialist Republics (Russian: Декларация и договор об образовании Союза Советских Социалистических Республик) officially created the Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union. It de jure legalised a political union of several Soviet republics that had existed since 1919 and created a new federal government whose key functions were centralised in Moscow. Its legislative branch consisted of the Congress of Soviets of the Soviet Union and the Central Executive Committee of the Soviet Union (TsIK), while the Council of People's Commissars composed the executive.

The Treaty, along with the Declaration of the Creation of the USSR was approved on 30 December 1922 by a conference of delegations from the Russian SFSR, the Transcaucasian SFSR, the Ukrainian SSR and the Byelorussian SSR. The Treaty and the Declaration were confirmed by the First All-Union Congress of Soviets and signed by heads of delegations – Mikhail Kalinin, Mikhail Tskhakaya, and Grigory Petrovsky, Alexander Chervyakov respectively on December 30, 1922. The treaty provided flexibility to admit new members. Therefore, by 1940 the Soviet Union grew from the founding four (or six, depending on whether 1922 or 1940 definitions are applied) republics to 16 republics.

Before the perestroika reforms of Mikhail Gorbachev that promoted a more liberal form of socialism, the formal ideology of the Communist Party of the Soviet Union (CPSU) was Marxism–Leninism, a form of socialism consisting of a centralised command economy with a vanguardist one-party state that aimed to realize the dictatorship of the proletariat. The Soviet Union's ideological commitment to achieving communism included the national communist development of socialism in one country and peaceful coexistence with capitalist countries while engaging in anti-imperialism to defend the international proletariat, combat the predominant prevailing global system of capitalism and promote the goals of Bolshevism. The state ideology of the Soviet Union – and thus Marxism–Leninism – derived and developed from the theories, policies, and political praxis of Karl Marx, Friedrich Engels, Vladimir Lenin, and Joseph Stalin.

Wicca (English: /ˈwɪkə/), is a modern pagan, syncretic, Earth-centred religion. Considered a new religious movement by scholars of religion, the path evolved from Western esotericism, developed in England during the first half of the 20th century, and was introduced to the public in 1954 by Gerald Gardner, a retired British civil servant. Wicca draws upon ancient pagan and 20th-century Hermetic motifs for theological and ritual purposes. Doreen Valiente joined Gardner in the 1950s, further building Wicca's liturgical tradition of beliefs, principles, and practices, disseminated through published books as well as secret written and oral teachings passed along to initiates.

Many variations of the religion have grown and evolved over time, associated with a number of diverse lineages, sects, and denominations, referred to as traditions, each with its own organisational structure and level of centralisation. Given its broadly decentralised nature, disagreements arise over the boundaries that define Wicca. Some traditions, collectively referred to as British Traditional Wicca (BTW), strictly follow the initiatory lineage of Gardner and consider Wicca specific to similar traditions, excluding newer, eclectic traditions. Other traditions, as well as scholars of religion, apply Wicca as a broad term for a religion with denominations that differ on some key points but share core beliefs and practices.

A revived language is a language that at one point had no native speakers, but through revitalization efforts has regained native speakers.

The most frequent reason for extinction is the marginalisation of local languages within a wider dominant nation state, which might at times amount to outright political oppression. This process normally works alongside economic and cultural pressures for greater centralisation and assimilation. Once a language has become marginalised in this way, it is often perceived as being "useless" by its remaining speakers, who associate it with low social status and poverty, and consequently fail to pass it on to the next generation.
