Problem: As the campaigning season of 1789 began, Koca Yusuf Pasha, Grand Vizier of the Ottoman Empire, took steps to defend the provinces of Moldavia and Wallachia. He faced the prospect of offensives from two directions. To the northwest lay an Austrian army of 18,000 men under Coburg. Meanwhile, Suvorov was marching Russian troops into Moldavia from the northeast. Yusuf Pasha determined to attack the Austrian forces before they could link up with their Russian allies. To this end, he ordered Osman Pasha to lead an army of 30,000 men north to Focsani. The town was an important trade center strategically located on the border between Moldavia and Wallachia.Learning of the Ottoman approach, Coburg asked his Russian counterpart for assistance. Suvorov marched with 7,000 men. He left his position at Buirlad on July 28 and marched 40 miles in 28 hours to reach Coburg the next day on the Siret River.

In 1833, 78.9 per cent of secondary-school students were children of nobles and bureaucrats, by 1885 they were 49.1 per cent of such students. The proportion of commoners increased from 19.0 to 43.8 per cent, and the remaining percentage were the children of priests. In fear of an educated proletariat, Tsar Nicholas I of Russia limited the number of university students to 3,000 per year, yet there were 25,000 students, by 1894.

Problem: In the 1650s, Burma became entangled in the dynastic changes in China. In 1651, Ming armies fleeing from the Qing forces entered Kengyun , which had paid tribute to both China and Burma. King Pindale sent five regiments to the front in October 1651. But the armies were driven back by the Ming in December 1651. Pindale would not contest again. In 1658, Zhu Youlang, one of the sons of the last Ming emperor, and his 700 followers were given permission to stay at Sagaing. In early 1659, other fleeing Ming armies entered the Shan states, and occupied Nyaungshwe and Mone with the intention to set up a kingdom for their emperor. For the next two years, the Ming forces proved a menace to Upper Burma. Not only Pindale could not drive out the Ming but it was the Ming that continually threatened the Burmese capital itself, and ransacked Upper Burma districts. On 4 June 1661, Pye Min overthrew his ineffectual brother, and took over the command. He finally drove out the Ming by November 1661. The problems were not yet over for the Burmese. On 21 December 1661, a Qing army of 20,000 under Gen. Wu Sangui showed up at Ava, demanding the surrender of the Ming emperor. The emperor was handed over on 15 January 1662, and the Qing forces left a week later.
