HISTORY (13)

Philip Y.L. Woo

The following is a brief

survey of some basic facts.

about China from 1898 to 19119

THE HUNDRED. DAY REFORM, 1898

A.Reasons:

17China's defeat in the

Sino-Japanese War (1894-

95)

2.New demands of Western

Powers in the Scramble for Concessions (1896-99'). B.Radical reformers:

1.Kang Yu-wei (1858-1927)= scholar-gentry background and education, explained China's tradition in. radically new ways, aroused anger of other scholars.

when hot.

(c) What is gas X!

(a) hat can be seen when an onia solution is added to solution

3?

Question 21

(a) explain, with the help of

ionic equationis, each of the follwoing observations. (1) When a copper wire is

placed in aqueous bilver nitrate solution for some time, it becomes coated- with white crystalline solid and a pale blue solution is resulted.

(ii) When carbon dioxide is pened into lime w ter, white precipitate is seen. but it dimelves again when an excess of carbon dioxide is pashed into it. (iii) Wien chlorine gas is.

passed into the colourless potassium iodide solution, it gradually becomes brown and finally, dark grey solids appear at the bot- tom of the test-tube. (iv) When acidified silver

nitrate is added to a metallic chloride solu- tion, white precipitate is observed. The precip - itate disappears when an excess of anconia solution is added to the mixture.

(b). An element called europium,

symbol Eu, exists naturally as a mixture of equal quan- tities of two isotores. They may be represented by the

2.Liang Ch'i-ch'ao (1873-

1929),K¦ang's follower. 3.Tan 5su-t'ung (1865-46),

advocating deep western- ization,freedom and equality.

Political activities of reformers:

A

1. Reform societies were set

up, journals for reform

were published; memorial

sent by scholars at

Peking to the dynasty. 2.The reformers.in power.

the Hundred Days of Reform (June 1898) a.Kuang-hau Emperor lent

support to reform. b.Reform edicts issued:

education and examina- tion updated, army re- organized,central government administra- tion to be made more. efficient, plans for local government. c.Overthrow of reformers:

reformers asked Yuan Shih-k ai (1859-1916) to capture press Dowager, but Yuan betray- ed reformers. Tz'u-hsi (Empresa Dowager) came back to power, Kuang- hsu lost influence. Fate of reformers: escape of Kang Yu-wei and Liang Ch'i-chao, six other reformers

(including Tan Ssu- tung) were killed.

d. Reasons for failure of

reform::

1)reform measures

aroused oppositions. from corrupt officials & Manchus (who feared Chinese dominance). )Objections of Confu- cian conservatives. 3)Lack of planning & far-sightedness, on the part of reformers. D. Continuity of reform ideas:

1.Moderate reform continued.

e.g. Chang Chih-tung's reform program. Chang's

idea, "Chinese learning as

the foundation; Western learning as the means" very popular.

2.Yen Fu translated Western ideas, in support of full- scale westerhization, liberalism, need to

strengthen China. Beginn- ing of Chinese national- ism.

THE BOXER UPRISING & LATE CHLING REFORM 1900-1911

A. Boxer Rebellion(1898-1901)

1.Origins of Boxer Movement:

a.Secret societies b.Anti-foreign ideas and

acts

b.hatred toward missionary

activities & anti- Christian ideas.

2. Different policies of

Ch'ing officials toward- Boxers:

a. Encouragement from

Manchu & reactionary officials.

b. Suppression by other

officials like Yuan

Shih-k'ai (in Shantung -in 1899)

ment in areas under pro- Boxer officials.

d. Boxers in Peking, attack- ing foreign legations. Tz tu-hai encouraged Boxers, declared war on all foreign: Powers. f.Viceroys like Li Hung-

chang & Chang Chih-

tung in the south

remained neutral..

3. Foreign expeditionary

force to Peking:

a.Defeat of Boxers & fall

of Peking

b.Escape of emperor &

Tzju-hei from Peking

4.Boxer Protocol 1901:

a.China had to pay large

indemnity.

b. Punishment of pro-Boxer

officials

5. Effects of Boxer Uprising a.China's national rights

further violated by

harsh Frotocol. /

b. Tzu-hsu realised need..

for reform, thus the Late Ch'ing reform (1901-11)

c.Political decentraliza- tion,as viceroys dis- obeyed the dynasty.

d. More people turned to welcome revolution, e.China's determination to fight foreigners checked foreign imper- falism, end to the Scramble for Concessions. e.Tensions between Japan & Russia in Manchuria, since Russla occupied the place during Boxer disturbances,

B.The Late Ch'ing deform"

(1901-1911)

1.Military reforms & power

of Yuan Shih-k'aig

a. Further modernization.

of Chinese army... b.Tzu-hai and Kuang-hsi

died in 1908, Yuan forced to retire.

Educational reforms: a.Abolition of civil

service exam system in 1905:

b.spread of modern schools

& Western studies e.Founding of Peking

University.

3.Political reforms:

a. Constitutional movement

due to demand in the provinces impact of Japanese victory in the Russo-Japanese War (1904-

05).

b. In 1908,creation of

local self-governments, in 1909, creation of provincial assembles, in 1910, creation of national assembly formation of the first cabinet in 1911.. Reasons for failure.

a. Education reforms gave

rise to patriotic students &

intellectuals hostile to the dynasty. b.Political reforms led

to further political decentralization and ⠀ disloyalty in provinces. c.Military reforms creat-

ed regional forces nearly independent of Peking's control. d.Tz'u-hsi was insincere. e. Really able officials were lacking to carry out reform f.The Dynasty's economic

conditions were poor. g.foreign imperialism

had harmful effects on China

h.Conservatism was strong.

in society.
