CBSE Class 9 History Chapter 2 Notes | Socialism in Europe and the Russian Revolution| Important History note for OAVs

   Class 9 History Chapter 2 Notes

     Socialism in Europe and the Russian Revolution 


         The French Revolution had a great impact on the world and brought about a dramatic change in the way in which society was formed. Before the 18th century, society was broadly divided into estate and orders. Economic and social power were controlled by the church and the aristocracy. Suddenly, after the revolution, it seemed possible to change this. New ideas about the individual rights and who controlled the social power began to be discussed in Europe, Asia and many part of the world. 


      The Age of Social change


After French Revolution many social and political changes took place all over Europe. Although not everyone in Europe wanted a complete Transformation of society. 

       People were kind of three types

a. Liberal  -  

    Liberal were the kind of people believed in change of society. They wanted a nation, which tolerate all religion. 

 They opposed unrestricted absolute power of the monarch. They argued for a representative, elected parliamentary government. 

They also  favoured a well- trained Independent judiciary. 

But these liberals were not Democrats and they did not favour Universal adult Franchise. They wished voting rights to be restricted to men of property. 


b.  Radicals -

    Radicals wanted a nation in which government was based on the majority of a country's population. 

  

  They supported women's right to vote. They were against the privileges of propertied class. Although they were not against private property but disliked the concentration of it in the hand of few. 


c. Conservatives -

    Conservatives were those who were in support of radicals and liberals. 

    Although they were not in favour of any changes but French revolution open theis mind to the need for changes. 

By 19th century, conservatives accepted that some changes was inevitable that the past had to be respected. 


     Industrial Society and Social Change


  This was the period of economical and social change. 

Men women and children were driven into industrial facilities for low wages.

  Revolutionaries who were processing plant proprietors felt that laborers' work should be encouraged. 


   Coming up Socialism in Europe

      Socialist Opposed Private property and claimed that it is the root of all social evils. 

      They believed that the rich class of the society only concern with their personal gain and they are not cared for the welfare of the lower class people who  made the property productive. 

      So they suggested that instead of individuals control, property should be controlled collectively. 

   Robert Owen sought to build a cooperative community called New Harmony in Indiana (USA). 

    French socialist Louis Blanc wanted the government to encourage cooperative and replace capitalist enterprises. 

    Karl Marx and Friedrich Engels

    Karl Marx and Friedrich Engels were two famous socialism who opposed capitalist society. 

  Karl Marx in his famous book 'Das Kapital'     raised voice for the Industrial labourers who were not get their share of profit comparison to their contribution. 

  He wanted production units should be nationalised. 

     Friedrich Engels joined Karl Marx to establish dictatorship of Proletariat. 

    Karl Marx and Friedrich Engels argued that industrial society was capitalist. Marx believed that to be free the workers themselves from capitalist exploitation, workers had to construct a radically society where all property would socially controlled. 


   Support for Socialism

 By the mid 19th century, 1870's  socialist ideas spread to every corner of Europe. Socialist formed an International body namely - 'The second International'. 

    Similar Association being formed in other part of the world.

Most of the Industries were owned by private Individuals. In craft units and small workshop working hours were 15 hours. Government supervised large factories to ensure limited working hours of 12 hours and minimum wages. 

Workers were divided by skills - Metal workers of St. Petersburg considered themselves aristocrats among workers. 

Women made of 31% of total workforce in factories by 1914.

Russian Peasants stand different from other European countries. Peasants were deeply religious. They refused to pay rent and sometimes murdered landlords. In 1902  these incidents took place in a large scale. Later it spread to all over Russia by 1905.

Impact of World war I on Russia

The war of 1914 had severely affected Industries in Russia which were less in numbers. 

Due to war railway lines broke down and the country was cut off from other supplier of industrial goods. 

Physically strong people recruited in wars.

Soldiers and striking laborers assembled to frame a 'soviet' or 'board' in a similar structure as the Duma met and it is named as the Petrograd Soviet. 

Soviet leaders and Duma leaders  framed a Provisional Government to run the country.

 Russia's future would be taken by a constituent assembly, chosen based on Universal adult suffrage. 

Petrograd  soviet had driven the February Revolution that  thrown out the monarchy in February 1917.


After February

In newly formed Provisional government the army officials, industrialist and landowners were powerful. But the liberals and socialist were under the elected government. 

As Restrictions on Public meeting and associations withdrawn like Petrograd soviet several Soviets were set up everywhere.

Bolsheviks signed a treaty with Germany at Brest Litovsk. 


CIVIL WAR

 A Civil war is fought between The Bolsheviks  ( the red) in one side and the Pro- Tsarist ( the white)and socialist revolutionaries (the green)  in 1918 - 1919.


In the process of civil war the Bolsheviks helped by the non-Russian people and Muslim Jadidists and took the control of former Russian empire by 1920.

They were given political autonomy in the USSR created by the Bolsheviks in 1922.


Stalinism and Collectivisation 


Joshep Stalin became the leader of Soviet Communist Party after the death of Lenin in January 1924.

  Stalian Policy

By 1924- 1928 , the towns in Russia were facing acute problem of grain supplies. 

In 1928 survey was conducted by party members. 

After 1929 , the Communist party forced the peasants to cultivate in collective lands. 

Those who opposed to this they got punished by the government. They were forced to remove from one's own country ( Deported) or to Exiled (forced to live away from own country) 


Large numbers of peasants did not liked to work in collective land showing different reasons. So Stalin government allowed few to cultivate in independent land. But the production did not increased immediately. 

Bad harvest of 1930-33 brought about 4 billion death. 


Global Influence of Russian Revolution

i. The Bolsheviks ideas inspired many colonies. 

ii. By the time of the outbreak of the second World War, the USSR had given socialism as a global face. 


Conclusion

After 1950s the style of government in the USSR changed. It's industry and agriculture had developed . It had denied the essential freedoms to it's citizens and carried out it's developmental projects through repressive policies. By the end of 20th century, the international reputation of the USSR as a socialist country had declined, though it was recognised that socialist were still enjoyed respect among its people.

Class 7 NCERT TIdes | Definition | What cause tides

                    TIDES


Definition - Periodic rise and fall of ocean water at regular interval, twice a day is called Tide. 

➡️  Tides are experienced in the ocean and seas. 

➡️ When the level of sea water  rises, it is high tide and when the level falls it is low tide. 


Causes - Tides are caused by the gravitational pull  of the moon and the sun on the earth. 

ii) The attraction of the moon is stronger because the moon is much closer to earth than the sun is. 

         The Opposite side of Gravitational force is known as centrifugal force. 

      


iii)  The height of tides depends upon the relative position of the moon and the sun with respect to the earth. 

iv) During full moon and new moon days, the sun, the moon and the earth are in the same line resulting in extra high tides. These are called Spring tides. 

  


When the moon is in the first and third quarter, the sun and moon are at right angles and the water gets drawn in  diagonally opposite directions. This results in low tides which are called neap tides. 





How tides are useful                                                   •     The rise in water level during high tides allows big ships   to enter or leave harbours safely. The port of Kandla in Gujarat and Diamond Harbour in West Bengal depend on such tides. 

•      During high tide, water rushes up the mouth of rivers. This helps large ships to move in and out of river ports like Kolkata, London, Hamburg, Rotterdam and Network. 


•   Tides helps in Fishing . During high tides more fish come near shore helping the fishermen to get plentiful catch

•  Tides also help to generate electricity. As the sea water gushes in during a high tide, it's energy can be tapped and used to generate electricity. India is yet to start utilising tidal energy.

Rocks - The Concept, Types and Uses| CTET |

 Rocks - Meaning - Types- Characteristics - Uses


                 ROCKS

                        ⬇

         Rocks are  Solid materials of  the Earth's Crust. It may hard or soft. They are of different composition size, texture and colours. 

       Rocks also include loose materials such as sand and silt. 

 Rocks are made up of one or more minerals but they do not have a definite chemical composition. 


                              TYPES

On the basis of formation rocks are of three types

              1.  Igneous Rocks

              2.  Sedimentary Rocks

              3.  Metamorphic Rocks



      IGNEOUS ROCKS

i) The term igneous derived from the Latin word            'ignis' - which means 'fire'

ii) Deep below the earth's, rocks are in a molten  state called Magma.when magma cools and solidifies, it forms a very hard rock known as igneous rocks. 

iii) There are two types of formation of igneous rocks

     a.  Extrusive igneous rock formation

                                   ⬇

                When the molten lava comes on Earth's  Surface and cools down rapidly on the                            crust , forms extrusive igneous rocks. 


      b.   Intrusive igneous rocks formation

                                   ⬇

        When molten magma cools down deep inside the earth's crust, the cooling process is slow and the rocks are called intrusive igneous rocks. 

               


Characteristics:-

i) Igneous rocks are called primary rocks because other types of rocks are formed from these rocks. 

ii) These rocks are hard and compact. They are impervious rocks and do not contain the remains of animals and plants. 

iii) Basalt, Granite, dolorite etc are ex of igneous rocks. 


   SEDIMENTARY ROCKS


i) The word ' Sedimentary' derived from the Latin word Sedimenter which means ' Settle down'. 

ii) Sedimentary rock is a type of rock formed by the deposition and hardening of layers of sediment. 

iii) These rocks are generally formed under water. 

iv) Sand Stone, limestone, shale, gravel, clay and conglomerate are the examples of sedimentary rock. 


Characteristics:-

i)  Sedimentary rocks are softer than igneous rocks. 

ii) These rocks contains fossils of plants and animals. Petroleum  and coal occurred in sedimentary rock. 

iii) these rocks constitute 70% of all rocks found on the surface of earth. 


METAMORPHIC ROCKS


i) The word metamorphic means change  of form. 

ii) These rocks formed when igneous and sedimentary rocks get changed due to heat and pressure. 

iii) Marble ( made from limestone),  Slate ( formed from shale) ,quartzite ( from sandstone) and Gneiss are example of metamorphic rocks. 


Characteristics:-

Metamorphic rocks are hard and take a long time in its formation. They are harder than the other rocks. 




                           Extra Facts 


  What is the difference between Magma and      Lava  ?? 

     Magma is the molten rocks that is in the underground  and Lava is molten rocks  that breaks through the Earth's  surface.
