Problem: Prime minister:

Problem: Some researchers believe that the first Russian settlement in Alaska was established in the 17th century. According to this hypothesis, in 1648 several koches of Semyon Dezhnyov's expedition came ashore in Alaska by storm and founded this settlement. This hypothesis is based on the testimony of Chukchi geographer Nikolai Daurkin, who had visited Alaska in 1764–1765 and who had reported on a village on the Kheuveren River, populated by "bearded men" who "pray to the icons". Some modern researchers associate Kheuveren with Koyuk River.
During which years didn't Nikolai Durkin visit Alaska?

During the rule of the Fatimid and Mamluk dynasties and their successor states in the medieval Middle East, many of the ruling elite founded madaris through a religious endowment known as the waqf. Not only was the madrasa a potent symbol of status but it was an effective means of transmitting wealth and status to their descendants. Especially during the Mamlūk period, when only former slaves could assume power, the sons of the ruling Mamlūk elite were unable to inherit. Guaranteed positions within the new madaris thus allowed them to maintain status. Madaris built in this period include the Mosque-Madrasah of Sultan Ḥasan in Cairo.
How were the madaris funded during the medieval period?
A: through a religious endowment


Context and question: German cinema dates back to the very early years of the medium with the work of Max Skladanowsky. It was particularly influential during the years of the Weimar Republic with German expressionists such as Robert Wiene and Friedrich Wilhelm Murnau. The Nazi era produced mostly propaganda films although the work of Leni Riefenstahl still introduced new aesthetics in film. From the 1960s, New German Cinema directors such as Volker Schlöndorff, Werner Herzog, Wim Wenders, Rainer Werner Fassbinder placed West-German cinema back onto the international stage with their often provocative films, while the Deutsche Film-Aktiengesellschaft controlled film production in the GDR.
What did Murnau produce during the Nazi era?

Question: Due to the patriarchal nature of Arab society, Arab men, including during the slave trade in North Africa, enslaved more black women than men. They used more black female slaves in domestic service and agriculture than males. The men interpreted the Qur'an to permit sexual relations between a male master and his female slave outside of marriage (see Ma malakat aymanukum and sex), leading to many mixed-race children. When an enslaved woman became pregnant with her Arab master's child, she was considered as umm walad or "mother of a child", a status that granted her privileged rights. The child was given rights of inheritance to the father's property, so mixed-race children could share in any wealth of the father. Because the society was patrilineal, the children took their fathers' social status at birth and were born free.
Is there an answer to this question: Who was enslaved more often?

Answer: black women

In the early 20th century, the writings of Albert Richardson were responsible for a re-awakening of interest in pure neoclassical design. Vincent Harris (compare Harris's colonnaded and domed interior of Manchester Central Reference Library to the colonnaded and domed interior by John Carr and R R Duke), Bradshaw Gass & Hope and Percy Thomas were among those who designed public buildings in the neoclassical style in the interwar period. In the British Raj in India, Sir Edwin Lutyens' monumental city planning for New Delhi marked the sunset of neoclassicism. In Scotland and the north of England, where the Gothic Revival was less strong, architects continued to develop the neoclassical style of William Henry Playfair. The works of Cuthbert Brodrick and Alexander Thomson show that by the end of the 19th century the results could be powerful and eccentric.
In what period did Percy Thomas design public building in neoclassical?
A:
interwar period
