Back in the 1920 the Indian National Congress the main party of the freedom struggle had promised that once the country won independence each major linguistic group would have its own province however after independence the Congress did not take any steps to honour this promise for India had been divided on the basis of religion faspite the wishes and efforts of Mahatma Gandhi freedom had. Come not to one nation but to two as a result of the partition of India more that aillion people had been killed in riots between Hindus and Muslims could the country afford further divisions on the basis of language?

Lifting Indian and Indians out of poverty and building a modern technical and industrial base were among the major objectives of the new nation in 1950 the government set up a planning commission to help design and executs suitable policies for economic development. There was a broad agreement on what was called a mixed economy model here both the state and the private sector would play important and complementary roles in increasing production and generating jobs. What specifically these roles were to be which industries should be initiated by the state and which by the market how to achieve a balance between the different regions and states was to be defined by the planning commission 

On 15 Auh 2007, India celebrated Sixty years of its existence as a free nation. How well has the country done in this time? And to what extent has it fulfilled the ideals set out in its constitution? That India is still united, and that it is still democratic are achievements that we might justly be proud of. Many foreign observers had felt that India could not survive as a single country that it would break up into many parts with each region or linguistic group seeking to form nation of its own. Others believed that it would come under military rule. However as many as thirteen general elections have been held since independence, as well as hundreds of state and local elections there is a free press as well as an independent judiciary finally the fact that people speak different languages or practise different faiths has not come in the way of national unity. On the other hand deep divisons persist bespite constitutional guarrrantees the untouchables or as they are now referred to the balits face violence and discrimination. In many parts of rural India they are not allowed access to water sources temples parks and other public pla ces. And despite the secular ideals enshrined in the constitution, there have been clashes between different religious groups in many states above all as many observers.

Production of wootz steel required a highly specialised technique of refining iron. But iron smelting in india was extremely common till the end of the nineteenth century. In bihar and cental india in particular. Every district has smelters that used local deposits of ore to produce iŕon which was widely used for the manufacture of implements  and  tools of daily  use. The furnaces were smelting was done by men while women worked the bellows. Pumping air that kept the charcoal burning.

{  . The sword of Tipu sultan and wootz steel.    }​​​​​​​​​​​​​​​​​​

we begin the story of Indian steel and iron metallurgy by recounting the famous story of Tipu sultan who ruled Mysore till 1799 fought four wars with the British and died fighting with his sword in his hand. Tipu's legendary swords are now part of valuable collections in museums in England. But do you know why the sword was so special? The sword had an incredibly hard and sharp edge that could easily rip through the opponent Armour. This quality of the sword came from a special type of high carbon steel called wootz which was produced all over south India.  Wootz steel when made into swords produced a very sharp edge with a flowing water pattern. This pattern came from very small carbon crystals embedded in the iron. Francis Buchanan who toured through Mysore in 1800 a year after Tipu sultan's death has left us an account of the technique by which wootz steel was produced in many hundreds of smelting furnaces in Mysore. In these furnaces iron was mixed with charcoal and put inside small clay pots. Through an intricate control of temperature. 

Mahatma Gandhi decided to initiate a new phase of movement against the British in the middle of the second world war. The British must quit India immediately he told them to the people he said do or die in your effort to fight the British but you must fight non violently. Gandhiji and other leaders were jailed at once but the movement spread lt specially attracted peasants and the youth who gave up their studies to joined it communications and symbols of state authority were attacked all over the country. In many areas the people set up their own governments. The first response of the British was severe repression by the end of 1943 over 90,000 people were arrested and around 1, 000 killed in police firing in many areas orders were given to machine gun crowds from airplanes. The rebellion however ultimately brought the raj to its knees. Bh
