Tretyakov Gallery in the context of "Islamic slave trade"

The history of slavery in the Muslim world was throughout the history of Islam with slaves serving in various social and economic roles, from powerful emirs to harshly treated manual laborers. Slaves were widely in labour in irrigation, mining, and animal husbandry, but most commonly as soldiers, guards, domestic workers. The use of slaves for hard physical labor early on in Muslim history led to several destructive slave revolts, the most notable being the Zanj Rebellion of 869–883. Many rulers also used slaves in the military and administration to such an extent that slaves could seize power, as did the Mamluks.

Most slaves were imported from outside the Muslim world. Slavery in the Muslim world did not have a racial foundation in principle, although this was not always the case in practice. The Arab slave trade was most active in West Asia, North Africa (Trans-Saharan slave trade), and Southeast Africa (Red Sea slave trade and Indian Ocean slave trade), and rough estimates place the number of Africans enslaved in the twelve centuries prior to the 20th century at between six million to ten million. The Ottoman slave trade came from raids into eastern and central Europe and the Caucasus connected to the Crimean slave trade, while slave traders from the Barbary Coast raided the Mediterranean coasts of Europe and as far afield as the British Isles and Iceland.

The Virgin of Vladimir, also known as Vladimir Mother of God, Our Lady of Vladimir (Russian: Владимирская икона Божией Матери), is a 12th-century Byzantine icon depicting the Virgin and Child and an early example of the Eleusa iconographic type. It is one of the most culturally significant and celebrated pieces of art in Russian history. Many consider it a national palladium with several miracles of historical importance to Russia being attributed to the icon. Following its near destruction in the thirteenth century, the work has been restored at least five times.

The icon was painted by an unknown artist most likely in Constantinople. It was sent to Kiev as a gift before being transferred to the Assumption Cathedral in Vladimir. It is traditionally said that the icon did not leave Vladimir until 1395, when it was brought to Moscow to protect the city from an invasion by Timur, although the historical accuracy of this claim is uncertain. By at least the sixteenth century, it was in the Dormition Cathedral in Moscow where it remained until it was moved to the State Tretyakov Gallery after the Russian Revolution.

A staff of office is a staff, the carrying of which often denotes an official's position, a social rank or a degree of social prestige.

Apart from the ecclesiastical and ceremonial usages mentioned below, there are less formal usages. A gold- or silver-topped cane can express social standing (or dandyism). Teachers or prefects in schools traditionally carried less elaborate canes which marked their right (and potential threat) to administer canings, and military officers carry a residual threat of physical punishment in their swagger sticks. Orchestral conductors have in their batons symbols of authority as well as tools of their trade.

Blachernitissa (Greek: Βλαχερνίτισσα), also called Theotokos of Blachernae (Θεοτόκος των Βλαχερνών, Θεοτόκος η Βλαχερνίτισσα) or Our Lady of Blachernae (Παναγία η Βλαχερνίτισσα), is a 7th-century encaustic icon representing the Most Holy Theotokos and Ever-Virgin Mary. It is also the name given to the Church built in honour of the Virgin Mary in the Blachernae section of Constantinople. The name Blachernae possibly derived from the name of a Vlach (sometimes written as Blach or Blasi), who came to Constantinople from the lower Danube.
