The last volcanic eruption of Mount Guntur in West Java occurs in October 1847.

Mount Guntur or Gunung Guntur, an active stratovolcano in western Java, is part of a complex of several overlapping stratovolcanoes about ten kilometers (six point two miles) northwest of the city of Garut.

The last eruption was in 1847. At an elevation of 2,249 m (7,379 ft), Mount Guntur rises about 1,500 m (4,900 ft) above the plain of Garut.

It has produced frequent explosive eruptions in the first half of nineteenth century, making it one of the most active volcanoes of western Java.

The name Guntur means "thunder" in the Indonesian language.


 







    October –

The Thai-Annamese War ends inconclusively in 1847.

The Cambodian King continues to pay tribute to the Annamese Emperor.

China's economic tensions, military defeats at Western hands, and anti-Manchu sentiments all combine to produce widespread unrest, especially in the south.

South China had been the last area to yield to the Qing conquerors and the first to be exposed to Western influence.

The southern Chinese province of Guangdong, the homeland of the Taiping people, is beset with accelerating social unrest.

After the first Opium War, government prestige declines, and officials lose their capacity to reconcile communal feuding.

The greatest among such conflicts is that between the native settlers and the so-called guest settlers: the clannish, industrious Hakka, a Han subgroup who had migrated in the late twelfth century from North China, to Kwangsi and western Guangdong, mainly from eastern Guangdong.

Hong Xiuquan, founding ruler of the Heavenly Kingdom, the youngest son of four children in a poor but proud Hakka family, had shown early signs of great intelligence, and his entire village sponsored him in his studies, hoping that he would eventually pass the Confucian civil service examination, enter the government bureaucracy, and bring wealth and honor to his family and friends.

Hung, an epileptic, had failed the civil service examination several times however, and, influenced by Christian teachings, had a series of visions and believed himself to be the son of God, the younger brother of Jesus Christ, sent to reform China.

His schoolmate Feng Yunshan, an able organizer, utilizes Hong's ideas to organize a new religious group, the Pai Shang-ti Hui ("God Worshipers"), which he forms among the impoverished miners, charcoal workers and peasants of central Kwangsi, most of whom belong to the Hakka.

In 1847, Hung joins Feng and the God Worshippers, and is immediately accepted as the new leader of the group.

Conditions in the countryside are deplorable, and sentiment runs high against the foreign Manchu rulers of China.

As a result, Hung and Feng begin to plot rebellion.

Hong's movement—perhaps under the impact of Protestant missions—is quite austere, and it opposes magic, idols, and belief in spirits.

He considers the New Testament to be authoritative for his new sect, and its rapid growth-aided by connections with other revolutionary movements-soon results in a genuine danger to the Manchu emperor.

The cholera epidemic in Russia that starts in 1847 will last until 1851, killing over one million people.

Among the liberal critics condemning Nikolai Gogol’s reactionary Selected Passages from Correspondence is the influential Vissarion Belinsky, now the foremost Russian literary critic and a leader of the progressive intelligentsia.

Widely known for his annual surveys of Russian literature and essays on major figures of Russian and world literature, Belinsky has attempted to synthesize his conception of literature as an organ of social progress with German idealist aesthetics.

A committed revolutionary, Belinsky believes that literature should, if necessary, sacrifice artistic excellence to social values.

Hermann von Helmholtz, with several other associates in the sciences, particularly Emil duBois-Reymond and Karl Ludwig, forms the so-called 1847, or mechanistic, school of physiology, which attempts to explain physiological phenomena in terms of chemistry and physics.

Helmholtz completes a series of papers published between 1843 and 1847 in which he applies these principles to animal heat and muscle contraction, then outlines the physical and philosophical basis of the law of the conservation of energy (a hot topic at this time) “On the Conservation of Energy.”

The Transylvanian Diet in 1847 enacts a law requiring the government to use Magyar.

Transylvania's Romanians protest in vain.

Serbian culture has made significant strides in the eighteenth and nineteenth centuries.

Dositej Obradovic, Vuk Karadzic (1787-1864), and other scholars have accelerated a national renaissance.

Obradovic had spread the Enlightenment to the Serbs through his translations and autobiography.

Collections of Serbian folk songs and poems edited by Karadzic in the 1820s and 30s have awakened pride in national history and traditions.

Karadzic, having also overcome clerical opposition to reform the Cyrillic alphabet and the Serbian literary language, translates the New Testament in 1847.

His work widens the concept of Serbian nationhood to include language as well as religious and regional identifications.

General Harry Smith, fresh from fighting the Sikhs in India the previous year, becomes Cape Colony governor in 1847.
