The kalinga war, however, become  a turning point in ashoka’s  life. The death and destruction in this war filled him with remorse.

 

Deeply influenced by the Buddhist teachings  of peace, non-violence and compassion, ashoka embraced Buddhism and devoted his life to the welfare of his subjects.

Ashoka replaced the policy of dig bijaya with dhamma vijaya .

Chandragupta maurya  was an able and ambitious ruler.

He built a bast empire, stretching from hindu kush in the west to Bengal in the east and from the Himalayas in the north to narmada in the south.

Chandragutpa maurya  was succeeded by his son bindusara.

During  his reign bindusara expanded the empire up to mysore.

He was succeeded by his son ashoka.

Ashoka  ascended the throne in 273BCE.

At that time powerful kingdom, kalinga was not under mauryan control.

Kalinga controlled the land sea routes to south india and south-east asia.

Ashoka attacked kalinga in 216 BCE and comquered it after a bitter struggle.

The mauryan empire reached the height of  its political power during ashoka’s rule.

It stretched from the hindu kush in the west to Brahmaputra in the east and from the Himalayas in the north to mysore in the south.

By the beginning of the 4^th century ce many small kingdoms and republics in north india were united under

The gupta dynasty, which dominated the history of india for the next 200 years.

The gupta rule is offen called the golden age of the Indian history of guptas.

Chandragupta.

Chandragupta 1, the founder of the gupta dynasty, ascended the throne of Magadha in 320 BCE.

He ruled from pataliputra  and expanded his kingdom as far as Allahabad.

He ruled for 15 years and took the title of maharaja dhiraja.

For the first time in Indian history, by the 4^th century BCE, a large empire was built in Indian under the mauryas.

The mauryan empire politically unified a large part of the country.

The two main sources of information on the mauryan period are Indian by megasthenes  and arthashastra by chanakya.

The rock and pilar edicts of ashoka provide valuable information as will.

The first king of the mauryan  dynasty was Chandragupta maurya.

In 322 BCE, he overthrew the last nanda king dhana nanda and seized the throne of magda.

During their nomadic life the prehistoric humans took shelter in caves to protect themselves form rain, heat and wind.

They decorated the wall of these caves with beautiful paintings of animal , birds , hunting scenes and human fihures.

Historians believe that these images also depict their religious beliefs.

The cave complex was opened to the public in 1948. By 1955, the carbon dioxide, heat, humidity, and other contaminants produced by 1,200 visitors per day had visibly damaged the paintings and introduced lichen on the walls. The cave was closed to the public in 1963 to preserve the art.

During  Neolithic age the lifestyle of human had improved a lot.

Human being had started building mud houses growing crops and domesticating animals.

They thus become food producers from gatheres.

The termination of the Neolithic period is marked by such innovations as the rise of urban civilization or the introduction of metal tools or writing. Again, the criteria vary with each case. The earliest known development of Neolithic culture was in SW Asia between 8000 B.C. and 6000 B.C.

In Egypt it is generally accepted that prehistory ended around 3500 B.C.E. whereas in New Guinea the end of the prehistoric era is set much more recently, at around 1900 C.E. The earliest historical document is said to be the Egyptian Narmer Palette,dated 3200 B.C.E.

By this time early human had discovered fire and tools had become smaller sharper and pointed.

Microlith  was a special stone tool used as a blade.

During  the Mesolithic age the climate became warmer and drier.

                               

The Mesolithic or Middle Stone Age. The last Ice Age glaciers of Central Europe retreated between 15,000 and 12,000 BC. The climate became increasingly warm. At the same time the forests spread to higher altitudes in the mountains.

          

                

Palaeolithic: Much of this diet would have consisted of meat (including marrow and animal organs like the liver, kidneys and brains that are extremely rich sources of nutrition), fish and shellfish. Leafy vegetables, fruit, nuts and insects making up the remaining part of their diet.

In short, neanderthals covered most of their body in cold environments, less so during the warm. They often wore gloves and shoes, but only wore hats during the coldest times. However, these clothes were likely just simple furs or skins, tied or just draped over their body.

          

The palaeolithic age or the old stone age dates back to mearly 2.5 million years ago. In this age, early human lived in caves and near rivers.

                                      

                       

During this time humans used stone to make tools and stone was used many times as part of the actual tool. Tools are objects that make our lives easier. A computer or smart phone are examples of modern-day tools. Paleolithic is a word that comes from the two Greek words palaios, meaning old, and lithos, meaning stone.

The life of the prehistoric  human depended largest on stone. That is why this period is also called the stone age their tools were made of stones.

They used these stone tools to defends themselves, hunt animals cut meat bones and trees, scrape skins of animals and stitch clothes.

Thousands of years ago humans had to collect food by hunting animals and gathering fruits and berries from forest they had to travel ling distance in search of water.

Prehistory  is the study of human life that existed many hundreds of thousand of year ago when humans did not know how to read or write the early humans were known as hominids, who where not human beings but shared similar characteristics to human beings.

All our information about this period comes from fossils and artefacts such as bones, tools and cave pantings.

Geographical of a place always influences its history. Why do you think all the major civilizations of the world such as the  Indus valley and the Egyptian flourished on the bank of river

This is because the rivers provided water for domestic use, irrigation and transportation. It promoted trade and led to the growth of towns and cities.

        

             

  

Long year ago we made a tryst with destiny, and now the time comes when we shall redeem our pledge, not wholly or in full measure, but very substantially. At the stroke of the midnight hour, when the world sleeps, india will awake to life and freedom. A moment comes, which comes but rarely in the  history ,  when an ages ends, and when the soul of a nation, long suppressed, finds utterance. It is fitting that at this solemn moment we take the pledge of dedication to the service of india and her people and to the still larger cause of humanity.
