(i) Paper was used by people to write holy text, letters and teachings of saints, ruler's chronicles, petitions and judicial records and for maintaining accounts and taxes.
(ii) Manuscripts were collected by wealthy people, rulers, temples and monasteries. These manuscripts were placed in libraries and archives that provided a lot of details to historians.

Rajputs word has been derived from 'Rajaputra', the son of a ruler. Between the eighth and fourteenth centuries, the term was applied to a body of warriors, who claimed Kshatriya caste status.
This term not only included rulers and chieftains but also commanders and soldiers. They served in the armies of different monarchs all over the subcontinent.

The time frame of medieval history is taken as one thousand years, from roughly 750 to 1750, which is further divided into two parts:
(a) Early medieval period
(b) Later medieval period
The medieval history is strongly associated with Islamic influence and rule in India. It also witnessed the rise and fall of many religion and dynasties.

In our city records are kept in Tehsil. The government officials writes these records. Yes, Archive manager manages it. Documents related to old history are stored there. Historians and Research scholars of history use it

Technological Changes Buses, cars, bikes, bicycles, auto-rickshaw are seen and people uses mobile telecommunication. Houses are tall, beautiful.
Economic Changes People are busy in money making by taking different professions.
Social Changes No jati, sub-caste, Jati Panchayat is seen, equality to all is maintained by the state. Rule of law and not the rule of king is there.

Economic Changes People now sell their produce in near by market. Cash crops are more widely grown.
Social Changes People now can eat, talk, sit with any caste, whosoever. Jati Panchayat is not so powerful than judicial court.
Cultural Changes People now talk usually in Hindi, not their particular dialect. Health and hygiene are taken care of.

In the medieval period as society became more differentiated, people were grouped into Jatis or sub-castes. They ranked on the basis of their backgrounds and their occupations.
Jatis framed their own rules and regulations to manage the conduct of their members. These regulations were enforced by an assembly of elders.They were described in some areas as the jati panchayat. Jatis were also required to follow the rules of their villages which were governed by a chieftain.

In the medieval period, we find the spread of peasant societies, the rise of regional and imperial state formations sometimes at the cost of pastoral and forest people. Medieval period shows the development of Hinduism and Islam and the arrival of European trading companies. Modern age shows a sense of material progress and intellectual advancement. Societies reached a certain level of prosperity.

'Time' is used by historians in a way, different from the other people in the society. It does not mean just a passing of hours, days or years. For them, it reflects the changes in social and economic organisation, in the persistence and transformation of different ideas and beliefs.

The term 'Hindustan' was first used by Minhaj-i- Siraj, a Persian chronicler, in the 13th century. Amir Khusrau, the notable poet, used the word 'Hind' for the first time in the 14th century in his poems. Mughal Emperor Babur used the term 'Hindustan' to describe the geography, the fauna and the culture of the inhabitants.

For any historians, time is not just passing of hours, days or years. Instead, it is the reflection of social, economic, cultural and religious changes that occur through the ages. Division of past events, happenings into large segments that is periods, make it easy to study time for any historians. British historians divided the history of India into three periods: Hindu, Muslim and British. 
This division was based on the idea that the religion of rulers was the only important historical change.
But this division ignored the rich diversity of the Indian subcontinent. Most historians take social and economic factors into account in order to characterise the major elements of different moments of the past. Historians thus faced difficulties to describe the entire period as one historical unit. 

In early days manuscripts'were handwritten. They used palm leaves which was difficult to maintain. The later paper became cheaper and more widely available. People used it to write holy texts, chronicles of rulers, letters and teachings of saints etc. There was no printing press in those days, so scribes copied manuscripts by hand.
As scribes copied manuscripts, sometimes they introduced changes according to their  own. So, the different manuscripts of the same text became substantially different from one another over the centuries. Historians have to read the different versions and guess what the author had originally written.

By 700 AD, many regions of Indian sub-continent already possessed distinct geographical dimensions and their own language and cultural characteristics. An empire comprises of the areas of many smaller regions or smaller kingdoms.
Pan-regional empire was developed in different dynasties. e.g. the empires of Chola, Tughluqs and Mughals without losing their distinctiveness.

The affairs of jatti were regulated in the following ways
Jatis were grouped or divided as per their family backgrounds and occupations that their family carried on. People had to accept these rules.
Jatis were the sub-castes as per the power, influence and resources controlled by members of the Jati. 
An assembly or group of elders was responsible for enforcing these regulations and were Called as Jati Panchayat. 
However, the Jati or caste of one area varies from that of other areas in many aspects.

My state is Delhi and Mughal Empire ruled over it. Delhi Sultanate was also ruling Delhi for long time. TughIaqs, Khaljis and Sayyids and the Slave dynasties ruled over Delhi. Indraprastha was the name of Delhi in ancient time ruled by the Pandavas.

Rulers made the exaggerated claims of conquests as they wanted to show others that they had control over large areas. They were the real rulers of the country. No other ruler could fight or challenge them. They showed power to make others fearful towards them.
