Document 4: Battle of Mohi: The Battle of Mohi (today Muhi), also known as Battle of the Sajó River or Battle of the Tisza River (11 April 1241), was the main battle between the Mongol Empire and the Kingdom of Hungary during the Mongol invasion of Europe. It took place at Muhi, southwest of the Sajó River. After the invasion, Hungary lay in ruins. Nearly half of the inhabited places had been destroyed by the invading armies.

Document 6: Crimean War: In the west, the Russians were dissuaded from attacking Vidin by the presence of the Austrian forces, which had swelled to 280,000 men. On 28 May 1854 a protocol of the Vienna Conference was signed by Austria and Russia. One of the aims of the Russian advance had been to encourage the Orthodox Christian Serbs and Bulgarians living under Ottoman rule to rebel. However, when the Russian troops actually crossed the River Pruth into Moldavia, the Orthodox Christians still showed no interest in rising up against the Turks.:131, 137 Adding to the worries of Nicholas I was the concern that Austria would enter the war against the Russians and attack his armies on the western flank. Indeed, after attempting to mediate a peaceful settlement between Russia and Turkey, the Austrians entered the war on the side of Turkey with an attack against the Russians in the Principalities which threatened to cut off the Russian supply lines. Accordingly, the Russians were forced to raise the siege of Silistra on 23 June 1854, and begin abandoning the Principalities.:185 The lifting of the siege reduced the threat of a Russian advance into Bulgaria.
Document 7: Han dynasty: During the turbulent reign of Wang Mang, Han lost control over the Tarim Basin, which was conquered by the Northern Xiongnu in AD 63 and used as a base to invade Han's Hexi Corridor in Gansu. Dou Gu (d. 88 AD) defeated the Northern Xiongnu at the Battle of Yiwulu in AD 73, evicting them from Turpan and chasing them as far as Lake Barkol before establishing a garrison at Hami. After the new Protector General of the Western Regions Chen Mu (d. AD 75) was killed by allies of the Xiongnu in Karasahr and Kucha, the garrison at Hami was withdrawn. At the Battle of Ikh Bayan in AD 89, Dou Xian (d. AD 92) defeated the Northern Xiongnu chanyu who then retreated into the Altai Mountains. After the Northern Xiongnu fled into the Ili River valley in AD 91, the nomadic Xianbei occupied the area from the borders of the Buyeo Kingdom in Manchuria to the Ili River of the Wusun people. The Xianbei reached their apogee under Tanshihuai (檀石槐) (d. AD 180), who consistently defeated Chinese armies. However, Tanshihuai's confederation disintegrated after his death.
Document 8: Crimean War: Russia had previously obtained recognition from the Ottoman Empire of the Tsar's role as special guardian of the Orthodox Christians in Moldavia and Wallachia. Now Russia used the Sultan's failure to resolve the issue of the protection of the Christian sites in the Holy Land as a pretext for Russian occupation of these Danubian provinces. Nicholas believed that the European powers, especially Austria, would not object strongly to the annexation of a few neighbouring Ottoman provinces, especially considering that Russia had assisted Austria's efforts in suppressing the Hungarian Revolution in 1849.
Document 9: Skhodnya River: Skhodnya River (), also known as Sukhodnya, Vkhodnya, Vykhodnya and Vskhodnya is a river in the northwest of Moscow, the second largest tributary (after the Yauza River) of the Moskva River. The length of the Skhodnya is 47 km (5 km in Moscow proper). The area of its basin is 17,2 km² (within the city). The Skhodnya originates near the village of Alabushevo (part of Zelenograd) and flows into the Moskva River near the Tushino Airfield. The Skhodnya River is connected with a derivational canal, which supplies water from the Volga River through the Khimki Reservoir (with the help of the Skhodnenskaya hydroelectric plant) to Moscow for sanitary irrigation.
Document 10: Crimean War: Nicholas felt that, because of Russian assistance in suppressing the Hungarian revolution of 1848, Austria would side with him, or at the very least remain neutral. Austria, however, felt threatened by the Russian troops in the Balkans. On 27 February 1854, the United Kingdom and France demanded the withdrawal of Russian forces from the principalities; Austria supported them and, though it did not declare war on Russia, it refused to guarantee its neutrality. Russia's rejection of the ultimatum caused the UK and France to enter the war.

Document 12: Kievan Rus': The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.

Document 14: Tura River: The Tura River (), also known as Dolgaya River (Long River, ) is a historically important Siberian river which flows eastward from the central Ural Mountains into the Tobol River, a part of the Ob River basin. The main town on it is Tyumen.
Document 15: Crimean War: Russia, as a member of the Holy Alliance, had operated as the "police of Europe", maintaining the balance of power that had been established in the Treaty of Vienna in 1815. Russia had assisted Austria's efforts in suppressing the Hungarian Revolution of 1848, and expected gratitude; it wanted a free hand in settling its problems with the Ottoman Empire — the "sick man of Europe". The United Kingdom could not tolerate Russian dominance of Ottoman affairs, as that would challenge the British domination of the eastern Mediterranean.
