Question: When was the Muslim conquest of the area where the screening was prevented?

full_context: Document 1: North African campaign: The campaign was fought between the Allies, many of whom had colonial interests in Africa dating from the late 19th century, and the Axis Powers. The Allied war effort was dominated by the British Commonwealth and exiles from German - occupied Europe. The United States officially entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942.
Document 2: Black people: Historians estimate that between the advent of Islam in 650CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million sub-Saharan Black Africans were enslaved by Arab slave traders and transported to the Arabian Peninsula and neighboring countries. This number far exceeded the number of slaves who were taken to the Americas. Several factors affected the visibility of descendants of this diaspora in 21st-century Arab societies: The traders shipped more female slaves than males, as there was a demand for them to serve as concubines in harems in the Arabian Peninsula and neighboring countries. Male slaves were castrated in order to serve as harem guards. The death toll of Black African slaves from forced labor was high. The mixed-race children of female slaves and Arab owners were assimilated into the Arab owners' families under the patrilineal kinship system. As a result, few distinctive Afro-Arab black communities have survived in the Arabian Peninsula and neighboring countries.
Document 3: Dwight D. Eisenhower: In November 1942, he was also appointed Supreme Commander Allied Expeditionary Force of the North African Theater of Operations (NATOUSA) through the new operational Headquarters Allied (Expeditionary) Force Headquarters (A(E)FHQ). The word "expeditionary" was dropped soon after his appointment for security reasons. The campaign in North Africa was designated Operation Torch and was planned underground within the Rock of Gibraltar. Eisenhower was the first non-British person to command Gibraltar in 200 years.
Document 4: Sahara: The Byzantine Empire ruled the northern shores of the Sahara from the 5th to the 7th centuries. After the Muslim conquest of Arabia (Arabian peninsula) the Muslim conquest of North Africa began in the mid-7th to early 8th centuries, Islamic influence expanded rapidly on the Sahara. By the end of 641 all of Egypt was in Muslim hands. The trade across the desert intensified. A significant slave trade crossed the desert. It has been estimated that from the 10th to 19th centuries some 6,000 to 7,000 slaves were transported north each year.
Document 5: Battleship (film): The film was originally planned to be released in 2011, but was rescheduled to May 18, 2012, in the United States. The film's world premiere took place in Tokyo on April 3, 2012. The event was attended by director Peter Berg, actors Taylor Kitsch, Brooklyn Decker, Alexander Skarsgård and Rihanna. Later on they initiated a Press Tour visiting Madrid, London and Cartagena de Indias to promote the film.
Document 6: Ike: Countdown to D-Day: The film does not have action sequences, focusing instead on the inner workings of Supreme Headquarters Allied Expeditionary Force that led to the successful D-Day invasion of World War II. Concentrating on decisions actually made by Eisenhower and the pressures brought to bear on him personally, it includes his personal relationship with British Prime Minister Winston Churchill (Ian Mune) and his own Chief of Staff, Lieutenant General Walter Bedell Smith, US Army (Timothy Bottoms).
Document 7: Middle Ages: Religious beliefs in the Eastern Empire and Persia were in flux during the late 6th and early 7th centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it.[J] Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634–635 and reaching Egypt in 640–641, Persia between 637 and 642, North Africa in the later 7th century, and the Iberian Peninsula in 711. By 714, Islamic forces controlled much of the peninsula in a region they called Al-Andalus.
Document 8: Middle Ages: Religious beliefs in the Eastern Empire and Iran were in flux during the late sixth and early seventh centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it. Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634–635 and reaching Egypt in 640–641, Persia between 637 and 642, North Africa in the later seventh century, and the Iberian Peninsula in 711. By 714, Islamic forces controlled much of the peninsula in a region they called Al-Andalus.The Islamic conquests reached their peak in the mid-eighth century. The defeat of Muslim forces at the Battle of Tours in 732 led to the reconquest of southern France by the Franks, but the main reason for the halt of Islamic growth in Europe was the overthrow of the Umayyad Caliphate and its replacement by the Abbasid Caliphate. The Abbasids moved their capital to Baghdad and were more concerned with the Middle East than Europe, losing control of sections of the Muslim lands. Umayyad descendants took over the Iberian Peninsula, the Aghlabids controlled North Africa, and the Tulunids became rulers of Egypt. By the middle of the 8th century, new trading patterns were emerging in the Mediterranean; trade between the Franks and the Arabs replaced the old Roman economy. Franks traded timber, furs, swords and slaves in return for silks and other fabrics, spices, and precious metals from the Arabs.
Document 9: The Spy in Black: "The Spy in Black" was filmed at Denham Studios, with location shooting at Northchurch Common in Berkhamsted, Hertfordshire and in Orkney, Scotland. The film wrapped production on 24 December 1938 and was released in the U.K. on 12 August 1939 – 22 days before the country again went to war with Germany. Its American premiere was held in New York City on 5 October of that year, and it went into general release two days later.
Document 10: Ossessione: Visconti adapted the script with a group of men he selected from the Milanese magazine "Cinema". The members of this group were talented filmmakers and writers and played a large role in the emerging neorealist movement: Mario Alicata, Gianni Puccini, Antonio Pietrangeli and Giuseppe De Santis. When "Ossessione" was completed and released in 1943, it was far from the innocent murder mystery the authorities had expected; after a few screenings in Rome and northern Italy, prompting outraged reactions from Fascist and Church authorities, the film was banned by the Fascist government reestablished in the German occupied part of Italy after the September 1943 armistice. Eventually the Fascists destroyed the film, but Visconti managed to keep a duplicate negative from which all existing prints have been made. After the war, "Ossessione" encountered more problems with mass distribution, this time in the United States. As a result of the wartime production schedule, Visconti had never obtained the rights to the novel and Metro-Goldwyn Mayer began production on another version of the film, directed by Tay Garnett ("The Postman Always Rings Twice", 1946), while the Fascist ban on Visconti's work was still in effect.
Document 11: Middle Ages: The Islamic conquests reached their peak in the mid-8th century. The defeat of Muslim forces at the Battle of Poitiers in 732 led to the reconquest of southern France by the Franks, but the main reason for the halt of Islamic growth in Europe was the overthrow of the Umayyad dynasty and its replacement by the Abbasid dynasty. The Abbasids moved their capital to Baghdad and were more concerned with the Middle East than Europe, losing control of sections of the Muslim lands. Umayyad descendants took over the Iberian Peninsula, the Aghlabids controlled North Africa, and the Tulunids became rulers of Egypt. By the middle of the 8th century, new trading patterns were emerging in the Mediterranean; trade between the Franks and the Arabs replaced the old Roman patterns of trade. Franks traded timber, furs, swords and slaves in return for silks and other fabrics, spices, and precious metals from the Arabs.
Document 12: Middle Ages: The migrations and invasions of the 4th and 5th centuries disrupted trade networks around the Mediterranean. African goods stopped being imported into Europe, first disappearing from the interior and by the 7th century found only in a few cities such as Rome or Naples. By the end of the 7th century, under the impact of the Muslim conquests, African products were no longer found in Western Europe. The replacement of goods from long-range trade with local products was a trend throughout the old Roman lands that happened in the Early Middle Ages. This was especially marked in the lands that did not lie on the Mediterranean, such as northern Gaul or Britain. Non-local goods appearing in the archaeological record are usually luxury goods. In the northern parts of Europe, not only were the trade networks local, but the goods carried were simple, with little pottery or other complex products. Around the Mediterranean, pottery remained prevalent and appears to have been traded over medium-range networks, not just produced locally.
Document 13: Casablanca (film): Although an initial release date was anticipated for early 1943, the film premiered at the Hollywood Theater in New York City on November 26, 1942, to coincide with the Allied invasion of North Africa and the capture of Casablanca. It went into general release on January 23, 1943, to take advantage of the Casablanca Conference, a high-level meeting in the city between British Prime Minister Winston Churchill and American President Franklin D. Roosevelt.  The Office of War Information prevented screening of the film to troops in North Africa, believing it would cause resentment among Vichy supporters in the region.
Document 14: Sahara: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
Document 15: Central African Republic: During the 16th and 17th centuries slave traders began to raid the region as part of the expansion of the Saharan and Nile River slave routes. Their captives were slaved and shipped to the Mediterranean coast, Europe, Arabia, the Western Hemisphere, or to the slave ports and factories along the West and North Africa or South the Ubanqui and Congo rivers. In the mid 19th century, the Bobangi people became major slave traders and sold their captives to the Americas using the Ubangi river to reach the coast. During the 18th century Bandia-Nzakara peoples established the Bangassou Kingdom along the Ubangi River.
