Russia (rɐˈsʲijə), officially the Russian Federation (p), is a country in Eurasia. At, Russia is the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 144 million people as of December 2017, excluding Crimea. About 77% of the population live in the western, European part of the country. Russia's capital Moscow is one of the largest cities in the world; other major cities include Saint Petersburg, Novosibirsk, Yekaterinburg and Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Finland, Estonia, Latvia, Lithuania and Poland (both with Kaliningrad Oblast), Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia and North Korea. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait. The East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, the medieval state of Rus arose in the 9th century. In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' ultimately disintegrated into a number of smaller states; most of the Rus' lands were overrun by the Mongol invasion and became tributaries of the nomadic Golden Horde in the 13th century. The Grand Duchy of Moscow gradually reunified the surrounding Russian principalities, achieved independence from the Golden Horde. By the 18th century, the nation had greatly expanded through conquest, annexation, and exploration to become the Russian Empire, which was the third largest empire in history, stretching from Poland on the west to Alaska on the east. Following the Russian Revolution, the Russian Soviet Federative Socialist Republic became the largest and leading constituent of the Union of Soviet Socialist Republics, the world's first constitutionally socialist state. The Soviet Union played a decisive role in the Allied victory in World War II, and emerged as a recognized superpower and rival to the United States during the Cold War. The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the world's second largest economy, largest standing military in the world and the largest stockpile of weapons of mass destruction. Following the dissolution of the Soviet Union in 1991, twelve independent republics emerged from the USSR: Russia, Ukraine, Belarus, Kazakhstan, Uzbekistan, Armenia, Azerbaijan, Georgia, Kyrgyzstan, Moldova, Tajikistan, Turkmenistan and the Baltic states regained independence: Estonia, Latvia, Lithuania; the Russian SFSR reconstituted itself as the Russian Federation and is recognized as the continuing legal personality and a successor of the Soviet Union. It is governed as a federal semi-presidential republic. The Russian economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2015. Russia's extensive mineral and energy resources are the largest such reserves in the world, making it one of the leading producers of oil and natural gas globally. The country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction. Russia is a great power as well as a regional power and has been characterised as a potential superpower. It is a permanent member of the United Nations Security Council and an active global partner of ASEAN, as well as a member of the G20, the Shanghai Cooperation Organisation (SCO), the Council of Europe, the Asia-Pacific Economic Cooperation (APEC), the Organization for Security and Co-operation in Europe (OSCE), and the World Trade Organization (WTO), as well as being the leading member of the Commonwealth of Independent States (CIS), the Collective Security Treaty Organization (CSTO) and one of the five members of the Eurasian Economic Union (EEU), along with Armenia, Belarus, Kazakhstan and Kyrgyzstan.

Sikhism (ਸਿੱਖੀ), or Sikhi,, from Sikh, meaning a "disciple", or a "learner"), is a monotheistic religion that originated in the Punjab region of the Indian subcontinent about the end of the 15th century. It is one of the youngest of the major world religions, and the fifth-largest. The fundamental beliefs of Sikhism, articulated in the sacred scripture Guru Granth Sahib, include faith and meditation on the name of the one creator, divine unity and equality of all humankind, engaging in selfless service, striving for social justice for the benefit and prosperity of all, and honest conduct and livelihood while living a householder's life. In the early 21st century there were nearly 25 million Sikhs worldwide, the great majority of them (20 million) living in Punjab, the Sikh homeland in northwest India, and about 2 million living in neighboring Indian states, formerly part of the Punjab. Sikhism is based on the spiritual teachings of Guru Nanak, the first Guru (1469–1539), and the nine Sikh gurus that succeeded him. The Tenth Guru, Guru Gobind Singh, named the Sikh scripture Guru Granth Sahib as his successor, terminating the line of human Gurus and making the scripture the eternal, religious spiritual guide for Sikhs.Louis Fenech and WH McLeod (2014),, 3rd Edition, Rowman & Littlefield,, pages 17, 84-85William James (2011), God's Plenty: Religious Diversity in Kingston, McGill Queens University Press,, pages 241–242 Sikhism rejects claims that any particular religious tradition has a monopoly on Absolute Truth. The Sikh scripture opens with Ik Onkar (ੴ), its Mul Mantar and fundamental prayer about One Supreme Being (God). Sikhism emphasizes simran (meditation on the words of the Guru Granth Sahib), that can be expressed musically through kirtan or internally through Nam Japo (repeat God's name) as a means to feel God's presence. It teaches followers to transform the "Five Thieves" (lust, rage, greed, attachment, and ego). Hand in hand, secular life is considered to be intertwined with the spiritual life., page.

Taqiyah (cap)

The taqiyah (also spelled tagiya; طاقية / ALA-LC: ṭāqīyah)Turkish: "takke", Urdu, Hindi "topi"; ٹوپی / ALA-LC: “ṭopī”, টুপি ṭupi, Somali: "Koofi") is a short, rounded skullcap. They are often worn for religious purposes; for example, Muslims believe that Muhammad used to keep his head covered, therefore making it mustahabb (i.e., it is commendable to cover the head in order to emulate him). Muslim men often wear them during the five daily prayers. When worn by itself, the taqiyah can be any colour. However, particularly in Arab countries, when worn under the keffiyeh headscarf, they are kept in a traditional white. Some Muslims wrap a turban around the cap, called an amamah in Arabic, which is often done by Shia and Sufi Muslims. In the United States and Britain taqiyas are usually referred to as "kufis". Topi is a type of taqiyah cap that is worn in India, Bangladesh, Pakistan, and other regions of South Asia. Many different types of topi caps include the Sindhi cap, worn in Sindh, and the crochet topi that is often worn at Muslim prayer services (see salat). The topi cap is often worn with salwar kameez, which is the national costume of Pakistan.
