Ottomanism ("Osmanlılık" or "Osmanlıcılık") was a concept which developed prior to the First Constitutional Era of the Ottoman Empire.
 Its proponents believed that it could solve the social issues that the empire was facing.
 Ottomanism was strongly influenced by thinkers such as Montesquieu and Rousseau and the French Revolution.
 It promoted equality among the "millet"s.
 The idea originated amongst the Young Ottomans in areas such as the acceptance of all separate ethnicities in the Empire regardless of their religion, i.e. they were all 'Ottomans' with equal rights.
 Put simply, Ottomanism stated that all subjects were equal before the law.
 Ideally, all citizens would share a geographical area, a language, culture, and a sense of a 'non-Ottoman' party who were different than them.
 The essence of the "millet" system was not dismantled, but secular organizations and policies were applied.
 Primary education, conscription, head tax and military service were to be applied to non-Muslims and Muslims alike.
Picasso's African Period, which was three years long, lasted from 1906 to 1909, was the period when Pablo Picasso painted in a style which was strongly influenced by African sculpture and particularly traditional African masks.

The Ostrogothic Papacy was a period from 493 to 537 where the papacy was strongly influenced by the Ostrogothic Kingdom, if the pope was not outright appointed by the Ostrogothic King.
 The selection and administration of popes during this period was strongly influenced by Theodoric the Great and his successors Athalaric and Theodahad.
 This period terminated with Justinian I's (re)conquest of Rome during the Gothic War (535–554), inaugurating the Byzantine Papacy (537-752).
The French Revolution (French: "Révolution française" ] ) was a period of far-reaching social and political upheaval in France that lasted from 1789 until 1799, and was partially carried forward by Napoleon during the later expansion of the French Empire.
 The Revolution overthrew the monarchy, established a republic, experienced violent periods of political turmoil, and finally culminated in a dictatorship under Napoleon that rapidly brought many of its principles to Western Europe and beyond.
 Inspired by liberal and radical ideas, the Revolution profoundly altered the course of modern history, triggering the global decline of absolute monarchies while replacing them with republics and liberal democracies.
 Through the Revolutionary Wars, it unleashed a wave of global conflicts that extended from the Caribbean to the Middle East.
 Historians widely regard the Revolution as one of the most important events in human history.
Tigran Hamasyan (Armenian: Տիգրան Համասյան ; born July 17, 1987) is an Armenian jazz pianist.
 He plays mostly original compositions, which are strongly influenced by the Armenian folk tradition, often using its scales and modalities.
 In addition to Tigran's folk influence, he is much influenced by American jazz traditions and to some extent, as on his album "Red Hail", by progressive rock.
 His solo album "A Fable" is most strongly influenced by Armenian folk.
 Even on his most overt jazz compositions and renditions of well-known jazz pieces, his improvisations often contain embellishments based on scales from Middle Eastern/South Western Asian traditions.
Mughlai cuisine consists of dishes developed in Medieval India at the centers of the Mughal Empire.
 It represents a combination of the cooking style and recipes of Central Asia and North India.
 The Mughlai cooking styles is used in the traditional cuisine of North India (especially Uttar Pradesh and Delhi), the Indian city of Hyderabad and the Pakistani city of Karachi (particularly among Muhajir migrants from India).
 The cuisine is strongly influenced by Central Asian cuisine, the region where the Turco-Mongol Mughal rulers originally hailed from, and it has in turn strongly influenced the regional cuisines of modern India, Pakistan and Bangladesh.
The art of Urartu refers to a historical and regional type of art from Urartu (Ararat), the ancient state of Western Asia which existed in the period from the 13th to the 6th centuries BC in the Armenian Highland.
 The art of Urartu was strongly influenced by nearby Assyria, the most prominent state of that period in the region.
 It peaked around the 8th century BC but was mostly looted, scattered and destroyed with the fall of Urartu about a century later.
The Cultural Revolution (or People's Revolution) in Libya was a period of political and social change in Libya.
 It started with Gaddafi's declaration of a cultural revolution during a speech in Zuwara on 15 April 1973.
 This came after increasing tensions between Gaddafi and his colleagues in the Revolutionary Command Council (RCC) had led him to agree to step down.
 Gaddafi had told the RCC that he would announce his resignation to the people at the Zuwara speech, but he instead surprised them with his declaration of the Cultural Revolution.
 By the end of the Cultural Revolution period, Gaddafi was the uncontested leader of Libya.
RX J0806.3+1527 or HM Cancri (sometimes shortened to "HM Cnc" or "J0806" after establishing identity) is an X-ray binary star system about 1600 ly away.
 It comprises two dense white dwarfs orbiting each other once every 321.5 seconds (in this system the "year" duration is of only 5.4 minutes), at an estimated distance of only 80000 km apart (about 1/5 the distance between the Earth and the Moon).
 The two stars orbit each other at speeds in excess of 400 km/s .
 The stars are estimated to be about half as massive as the Sun.
 Like typical white dwarfs, they are extremely dense, being composed of degenerate matter, and so have radii of order the radius of Earth.
 Astronomers believe that the two stars will eventually merge, based on data from many X-ray satellites, such as Chandra X-Ray Observatory, XMM-Newton and the Swift Gamma-Ray Burst Mission.
 These data show that the orbital period of the two stars is steadily decreasing at a rate of 1.2 milliseconds per year as they thus are getting closer by approximately 60 cm per day.
 At this rate, they can be expected to merge in approximately 340,000 years.
 With a revolution period of 5.4 minutes RX J0806 is the shortest orbital period binary system currently known.
