Question: In 1939 East Prussia had 2.49 million inhabitants, 85% of them ethnic Germans, the others Poles in the south who, according to Polish estimates numbered in the interwar period around 300,000-350,000, the Latvian speaking Kursenieki, and Lietuvininkai who spoke Lithuanian in the northeast. Most German East Prussians, Masurians, Kursieniki, and Lietuvininkai were Lutheran, while the population of Ermland was mainly Roman Catholic due to the history of its bishopric. The East Prussian Jewish Congregation declined from about 9,000 in 1933 to 3,000 in 1939, as most fled from Nazi rule. Those who remained were later deported and killed in the Holocaust.

Question: The Late Middle Ages in Europe as a whole correspond to the Trecento and Early Renaissance cultural periods in Italy. Northern Europe and Spain continued to use Gothic styles, which became increasingly elaborate in the 15th century, until almost the end of the period. International Gothic was a courtly style that reached much of Europe in the decades around 1400, producing masterpieces such as the Très Riches Heures du Duc de Berry. All over Europe secular art continued to increase in quantity and quality, and in the 15th century the mercantile classes of Italy and Flanders became important patrons, commissioning small portraits of themselves in oils as well as a growing range of luxury items such as jewellery, ivory caskets, cassone chests, and maiolica pottery. These objects also included the Hispano-Moresque ware produced by mostly Mudéjar potters in Spain. Although royalty owned huge collections of plate, little survives except for the Royal Gold Cup. Italian silk manufacture developed, so that western churches and elites no longer needed to rely on imports from Byzantium or the Islamic world. In France and Flanders tapestry weaving of sets like The Lady and the Unicorn became a major luxury industry.
Is there an answer to this question: What is a notable masterpiece of the International Gothic style?

Answer: the Très Riches Heures du Duc de Berry


Question: The Pacific War saw the Allied powers pitted against the Empire of Japan, the latter briefly aided by Thailand and to a much lesser extent by its Axis allies, Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the United States Army Air Forces, accompanied by the Soviet invasion of Manchuria on 8 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal and official surrender of Japan took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. Following its defeat, Japan's Shinto Emperor stepped down as the divine leader through the Shinto Directive, because the Allied Powers believed this was the major political cause of Japan's military aggression and deconstruction process soon took place to install a new liberal-democratic constitution to the Japanese public as the current Constitution of Japan.
Is there an answer to this question: What was the process called whereby the leader of Japan stepped down?

Answer: Shinto Directive
