Background: Selim III (Ottoman Turkish: slym thlth Selim-i salis) (24 December 1761 - 28 July 1808) was the reform-minded Sultan of the Ottoman Empire from 1789 to 1807. The Janissaries eventually deposed and imprisoned him, and placed his cousin Mustafa on the throne as Mustafa IV. Selim was subsequently killed by a group of assassins.
Context: Selim introduced domestic reforms to strengthen his government. He solicited suggestions throughout the governing institutions. As a basis for change: he created a new treasury, filled in large part from confiscatory punishment leveled at fief holders who had ceased to respect their military obligations, schools were opened, attention was given to printing and to the circulation of Western translations, and young Turks were sent to Europe for further study. The most significant reforms, however, involved the military. The navy was strengthened, and a navigation school was opened. The army commissariat was changed, officer training was improved, the Bosphorus forts were strengthened, the artillery was revitalized, and the new engineering school was reorganized. The major innovation was the founding of a new body of regular troops known as the Nizam-i-Cedid (new regulation), a term also applied to the reforms as a whole. A former Turkish lieutenant in the Russian army formed the first of these new units, uniformed, well disciplined and drilled, in 1792. Other units followed, involving, in some instances, extensive barracks building with related town facilities, such as the mosques and baths of Scutari. Such buildings constitute Selim's major architectural legacy.  Before the reforms, education in the Ottoman Empire had not been a state responsibility but had been provided by the education for Muslims. The first inroads into the system had been made with the creation of naval engineering, military engineering, medical and military science colleges. In this way specialized Western-type training was grafted onto the traditional system to produce specialists for the army. Similar institutions for diplomats and administrators were founded, including the translation bureau and the civil service school the latter was reorganized and eventually became the political science department of the University of Ankara and the major training center for higher civil servants.  The first comprehensive plan for state education was put forward. It provided for a complete system of primary and secondary schools leading to the university level, all under the Ministry of Education. A still more ambitious educational plan, inaugurated in 1869, provided for free and compulsory primary education. Both schemes progressed slowly because of a lack of money, but they provided a framework within which development toward a systematic, secular educational program could take place. There were more than 36,000 Ottoman schools, although the great majority were small, traditional primary schools. The development of the state system was aided by the example of progress among the non-Muslim millet schools, in which the education provided was more modern than in the Ottoman schools included more than 1,800 Greek schools with about 185,000 pupils and some 800 Armenian schools with more than 81,000 pupils. Non-Muslims also used schools provided by foreign missionary groups in the empire

Problem: Background: Celtic Frost () were a Swiss heavy metal band from Zurich. They are known for their strong influence on the development of extreme metal. Formed in 1982 as Hellhammer, the band became Celtic Frost in 1984 and was active until 1993. It re-formed in 2001 and disbanded following frontman Tom Gabriel Fischer's departure in 2008.
Context: One of their more influential recordings was 1985's To Mega Therion which did not feature Ain on bass, but stand-in Dominic Steiner. The cover artwork is a painting by H.R. Giger entitled Satan I. The album was a major influence on the then-developing death metal and black metal genres. Ain did return after the album was recorded however. In 1987 followed Into the Pandemonium. The album is more varied than many of Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs, the album's recurring industrial-influenced rhythmic songs of demons and destruction, traditional Frost styled songs about dreams and fear, and a dark, classical piece with female vocals.  The album is vastly different from the band's previous work and cemented its late 80s avant-garde metal term; it is also a departure from the extreme style found on the band's previous albums, Morbid Tales and To Mega Therion that Celtic Frost had become known for. However, it does have the recurring symphonic elements found on previous albums. The album has a more classic heavy metal style within the songs with elements of industrial, classical and gothic rock, and even has an industrial/electronic body music (EBM)-inspired rhythm in "One in Their Pride". It does have a few black metal elements remaining in Warrior's vocals, though, and some thrash-influenced guitar riffs.  These albums were some of the pivotal LPs for underground metal and introduced a new and more varied sound. Celtic Frost, along with Venom and Bathory were pioneers in the still underground black metal scene, although Celtic Frost were much more experimental with the addition of classical instruments, operatic female vocals and sampling. Celtic Frost was often labeled by critics as avant-garde metal.
