Under the leadership of William and his Minister President Otto von Bismarck, Prussia achieved the unification of Germany and the establishment of the German Empire. Despite his long support of Bismarck as Minister President, William held strong reservations about some of Bismarck's more reactionary policies, including his anti-Catholicism and tough handling of subordinates. In contrast to the domineering Bismarck, William was described as polite, gentlemanly and, while a staunch conservative, more open to certain classical liberal ideas than his grandson Wilhelm II.

paragraph_text: ``Snow White ''is a 19th - century German fairy tale which is today known widely across the Western world. The Brothers Grimm published it in 1812 in the first edition of their collection Grimms' Fairy Tales. It was titled in German: Sneewittchen (in modern orthography Schneewittchen) and numbered as Tale 53. The name Sneewittchen was Low German and in the first version it was translated with Schneeweißchen. The Grimms completed their final revision of the story in 1854.

paragraph_text: Italian unification was the political and social movement that annexed different states of the Italian peninsula into the single state of Italy in the 19th century. There is a lack of consensus on the exact dates for the beginning and the end of this period, but many scholars agree that the process began with the end of Napoleonic rule and the Congress of Vienna in 1815, and approximately ended with the Franco-Prussian War in 1871, though the last città irredente did not join the Kingdom of Italy until after World War I.

paragraph_text: During the following years Northumbria repeatedly changed hands between the English kings and the Norwegian invaders, but was definitively brought under English control by Eadred in 954, completing the unification of England. At about this time, Lothian, the northern part of Northumbria (Roman Bernicia), was ceded to the Kingdom of Scotland. On 12 July 927 the monarchs of Britain gathered at Eamont in Cumbria to recognise Æthelstan as king of the English. This can be considered England's' foundation date ', although the process of unification had taken almost 100 years.

paragraph_text: The unification of Germany into a politically and administratively integrated nation state officially occurred on 18 January 1871, in the Hall of Mirrors at the Palace of Versailles in France. Princes of the German states, excluding Austria, gathered there to proclaim Wilhelm I of Prussia as German Emperor after the French capitulation in the Franco - Prussian War. Unofficially, the de facto transition of most of the German - speaking populations into a federated organization of states had been developing for some time through alliances formal and informal between princely rulers -- but in fits and starts; self - interests of the various parties hampered the process over nearly a century of autocratic experimentation, beginning in the era of the Napoleonic Wars, which saw the dissolution of the Holy Roman Empire of the German Nation (1806), and the subsequent rise of German nationalism.

paragraph_text: Upon unifying, Italy had a predominantly agrarian society as 60% of the active population worked in agriculture. Advances in technology, the sale of vast Church estates, foreign competition along with export opportunities rapidly transformed the agricultural sector in Italy shortly after unification. However, these developments did not benefit all of Italy in this period, as southern Italy's agriculture suffered from hot summers and aridity damaged crops while the presence of malaria prevented cultivation of low-lying areas along Italy's Adriatic Sea coast.

paragraph_text: A three-year civil war followed his death. By the Treaty of Verdun (843), a kingdom between the Rhine and Rhone rivers was created for Lothair to go with his lands in Italy, and his imperial title was recognised. Louis the German was in control of Bavaria and the eastern lands in modern-day Germany. Charles the Bald received the western Frankish lands, comprising most of modern-day France. Charlemagne's grandsons and great-grandsons divided their kingdoms between their descendants, eventually causing all internal cohesion to be lost.[N] In 987 the Carolingian dynasty was replaced in the western lands, with the crowning of Hugh Capet (r. 987–996) as king.[O][P] In the eastern lands the dynasty had died out earlier, in 911, with the death of Louis the Child, and the selection of the unrelated Conrad I (r. 911–918) as king.

paragraph_text: During the Risorgimento, proponents of Italian republicanism and Italian nationalism, such as Alessandro Manzoni, stressed the importance of establishing a uniform national language in order to better create an Italian national identity. With the unification of Italy in the 1860s, standard Italian became the official national language of the new Italian state, while the various unofficial regional languages of Italy gradually became regarded as subordinate "dialects" to Italian, increasingly associated negatively with lack of education or provincialism. However, at the time of the Italian Unification, standard Italian still existed mainly as a literary language, and only 2.5% of Italy's population could speak standard Italian.

paragraph_text: The Napoleonic Wars were the cause of the final dissolution of the Holy Roman Empire, and ultimately the cause for the quest for a German nation state in 19th-century German nationalism. After the Congress of Vienna, Austria and Prussia emerged as two competitors. Austria, trying to remain the dominant power in Central Europe, led the way in the terms of the Congress of Vienna. The Congress of Vienna was essentially conservative, assuring that little would change in Europe and preventing Germany from uniting. These terms came to a sudden halt following the Revolutions of 1848 and the Crimean War in 1856, paving the way for German unification in the 1860s. By the 1820s, large numbers of Jewish German women had intermarried with Christian German men and had converted to Christianity. Jewish German Eduard Lasker was a prominent German nationalist figure who promoted the unification of Germany in the mid-19th century.

paragraph_text: Giuseppe Sirtori (17 April 1813 – 18 September 1874) was an Italian soldier, patriot and politician who fought in the unification of Italy.

Italy entered the war on 10 June 1940 and attempted an invasion of France.

paragraph_text: A widespread belief says that in June 1889 the pizzaiolo Raffaele Esposito, Pizzeria Brandi's chef, invented a dish called ``Pizza Margherita ''in honor of the Queen of Italy, Margherita of Savoy, and the Italian unification, since toppings are tomato (red), mozzarella (white) and basil (green), representing the same colors of the national flag of Italy.

paragraph_text: Historians debate whether Otto von Bismarck -- Minister President of Prussia -- had a master plan to expand the North German Confederation of 1866 to include the remaining independent German states into a single entity or simply to expand the power of the Kingdom of Prussia. They conclude that factors in addition to the strength of Bismarck's Realpolitik led a collection of early modern polities to reorganize political, economic, military, and diplomatic relationships in the 19th century. Reaction to Danish and French nationalism provided foci for expressions of German unity. Military successes -- especially those of Prussia -- in three regional wars generated enthusiasm and pride that politicians could harness to promote unification. This experience echoed the memory of mutual accomplishment in the Napoleonic Wars, particularly in the War of Liberation of 1813 -- 14. By establishing a Germany without Austria, the political and administrative unification in 1871 at least temporarily solved the problem of dualism.

paragraph_text: From Italy, the disease spread northwest across Europe, striking France, Spain, Portugal and England by June 1348, then turned and spread east through Germany and Scandinavia from 1348 to 1350. It was introduced in Norway in 1349 when a ship landed at Askøy, then spread to Bjørgvin (modern Bergen) and Iceland. Finally it spread to northwestern Russia in 1351. The plague was somewhat less common in parts of Europe that had smaller trade relations with their neighbours, including the Kingdom of Poland, the majority of the Basque Country, isolated parts of Belgium and the Netherlands, and isolated alpine villages throughout the continent.
