Kazan in the context of "Volga Federal District"

Our Lady of Kazan, also called Mother of God of Kazan (Russian: Казанская Богоматерь, romanized: Kazanskaya Bogomater'), is a holy icon of the highest stature within the Russian Orthodox Church, representing the Virgin Mary as the protector and patroness of the city of Kazan, and a palladium of all of Russia and Rus', known as the Holy Protectress of Russia. As is the case for any holy entity under a Patriarchate in communion within the greater Eastern Orthodox Church, it is venerated by all Orthodox faithful.

According to legend, the icon was originally acquired from Constantinople, lost in 1438, and miraculously recovered in pristine state over 140 years later in 1579. Two major cathedrals, the Kazan Cathedral, Moscow, and the Kazan Cathedral, St. Petersburg, are consecrated to Our Lady of Kazan, and they display copies of the icon, as do numerous churches throughout the land. The original icon in Kazan was stolen, and probably destroyed, in 1904.

Religious pluralism is an attitude or policy regarding the diversity of religious belief systems co-existing in society. It can indicate one or more of the following:

• Recognizing and tolerating the religious diversity of a society or country, promoting freedom of religion, and defining secularism as neutrality (of the state or non-sectarian institution) on issues of religion as opposed to opposition of religion in the public forum or public square that is open to public expression, and promoting friendly separation of religion and state as opposed to hostile separation or antitheism espoused by other forms of secularism.
• Any of several forms of religious inclusivism. One such worldview holds that one's own religion is not the sole and exclusive source of truth, and thus acknowledges that at least some truths and true values exist in other religions. Another concept is that two or more religions with mutually exclusive truth claims are equally valid; this may be considered a form of either toleration (a concept that arose as a result of the European wars of religion) or moral relativism.
• Perennialism (based on the concept of philosophia perennis) is the understanding that the exclusive claims of different religions turn out, upon closer examination, to be variations of universal truths that have been taught since time immemorial. While some perennialists are universalists who accept religious syncretism, those of the Traditionalist School reject it, and uphold the importance of the historical, "orthodox" faiths.
• Sometimes as a synonym for ecumenism, i.e., the promotion of some level of unity, co-operation, and improved understanding between different religions or different denominations within a single religion.
• As a term for the condition of harmonious co-existence between adherents of different religions or religious denominations.

Boris Nikolayevich Yeltsin (1 February 1931 – 23 April 2007) was a Russian politician and statesman who served as President of Russia from 1991 to 1999. He was a member of the Communist Party of the Soviet Union (CPSU) from 1961 to 1990. He later stood as a political independent, during which time he was viewed as being ideologically aligned with liberalism.

Yeltsin was born in Butka, Ural Oblast. Growing up in Kazan and Berezniki, he worked in construction after studying at the Ural State Technical University. After joining the Communist Party, he rose through its ranks, and in 1976, he became First Secretary of the party's Sverdlovsk Oblast committee. Yeltsin was initially a supporter of the perestroika reforms of Soviet leader Mikhail Gorbachev. He later criticized the reforms as being too moderate and called for a transition to a multi-party representative democracy. In 1987, he was the first person to resign from the Politburo of the Communist Party of the Soviet Union, which established his popularity as an anti-establishment figure and after which he earned the reputation of the leader of the anti-communist movement. In 1990, he was elected chair of the Russian Supreme Soviet and in 1991 was elected president of the Russian Soviet Federative Socialist Republic (RSFSR), becoming the first popularly-elected head of state in Russian history. Yeltsin allied with various non-Russian nationalist leaders and was instrumental in the formal dissolution of the Soviet Union in December of that year. With the dissolution of the Soviet Union, the RSFSR became the Russian Federation, an independent state. Through that transition, Yeltsin remained in office as president. He was later re-elected in the 1996 Russian presidential election, which critics assert was rigged.

Konstantin Sergeevich Mereschkowski (Russian: Константи́н Серге́евич Мережко́вский, IPA: [mʲɪrʲɪˈʂkofskʲɪj]; 4 August 1855 [O.S. 23 July] – 9 January 1921) was a Russian biologist and botanist, active mainly around Kazan, whose research on lichens led him to propose the theory of symbiogenesis – that larger, more complex cells (of eukaryotes) evolved from the symbiotic relationship between less complex ones. He presented this theory in 1910, in his work, The Theory of Two Plasms as the Basis of Symbiogenesis, a New Study of the Origins of Organisms, although the fundamentals of the idea had already appeared in his earlier 1905 work, The nature and origins of chromatophores in the plant kingdom.

Tatarstan, officially the Republic of Tatarstan, sometimes also called Tataria, is a republic of Russia located in Eastern Europe. It is a part of the Volga Federal District; and its capital and largest city is Kazan, an important cultural centre in Russia. The region's main source of wealth is oil with a strong petrochemical industry.

The republic borders the oblasts of Kirov, Ulyanovsk, Samara and Orenburg, as well as the republics of Mari El, Udmurtia, Chuvashia and Bashkortostan. Tatarstan has strong cultural, linguistic and ethnic ties with its eastern neighbour, Bashkortostan, which is also a republic of Russia. The area of Tatarstan is 68,000 square kilometres (26,000 sq mi), occupying 0.4% of the total surface of the country. As of the 2021 Census, the population of Tatarstan was 4,004,809.

The Kama (UK: /ˈkæmə/ KA-mə, US: /ˈkɑːmə/ KAH-mə; Russian: Кама [ˈkamə]; Udmurt: Кам), also known as the Chulman (/tʃuːlˈmɑːn/ chool-MAHN; Tatar: Чулман, romanized: Çulman [tɕuɫˈmɑn]), is a 1,805-kilometre (1,122 mi) long river in Russia. It has a drainage basin of 507,000 square kilometres (196,000 sq mi). It is the longest left tributary of the Volga and the largest one in discharge. At their confluence, in fact, the Kama is even larger in terms of discharge than the Volga.

It starts in the Udmurt Republic, near Kuliga, flowing northwest for 200 kilometres (120 mi), turning northeast near Loyno for another 200 kilometres (120 mi), then turning south and west in Perm Krai, flowing again through the Udmurt Republic and then through the Republic of Tatarstan, where it meets the Volga south of Kazan.

Pan-Turkism (Turkish: Pan-Türkizm) or Turkism (Turkish: Türkçülük or Türkizm) is a political movement that emerged during the 1880s among Turkic intellectuals who lived in the Russian region of Kazan (Tatarstan), South Caucasus (modern-day Azerbaijan) and the Ottoman Empire (modern-day Turkey), with its aim being the cultural and political unification of all Turkic peoples. Turanism is a closely related movement but it is a more general term, because Turkism only applies to Turkic peoples. However, researchers and politicians who are steeped in the pan-Turkic ideology have used these terms interchangeably in many sources and works of literature.

Although many of the Turkic peoples share historical, cultural and linguistic roots, the rise of a pan-Turkic political movement is a phenomenon of the 19th and 20th centuries. Ottoman poet Ziya Gökalp defined pan-Turkism as a cultural, academic, and philosophical and political concept advocating the unity of Turkic peoples. Ideologically, it was premised on social Darwinism. Pan-Turkism has been characterized by pseudoscientific theories known as Pseudo-Turkology.

The 2024 BRICS summit was the sixteenth annual BRICS summit, held in Kazan, Russia. It was the first BRICS summit to include Egypt, Ethiopia, Iran, and the United Arab Emirates as members, following their accession to the organization at the 15th BRICS summit.

The Temple of All Religions (Russian: Храм всех религий, Tatar: Барлык диннәр гыйбәдәтханәсе, romanized: Barlıq dinnär ğibädätxanäse) or the Universal Temple (Russian: Вселенский храм) is an architectural complex in the Staroye Arakchino Microdistrict of Kazan, Russia. It consists of several types of religious architecture including an Orthodox church, a mosque, and a synagogue, among others. It is currently under construction since 1992, started by local artist and philanthropist Ildar Khanov (1940 - 2013). The structure now serves as a cultural center and a residence for Khanov's brother and sister, who both continue to serve as guides and supervisors of the complex.

Khanov was known for his efforts in the treatment of alcoholism, drug addiction, and various other addictions. His patients helped him to maintain and develop the Temple, either by direct involvement in the construction work or through sponsorship.
