Unravelling History through Visualisation

 Learning and Teaching History: 

Unravelling History through Visualisation 

While teaching history, I have often given students a group activity. To introduce the activity, I first take them back in time and place them in the situation they are about to explore.

“Imagine that you are working in the intelligence department of Chhatrapati Shivaji Maharaj’s army. Bahirji Naik has assigned you the responsibility of gathering information about the situation in Surat before the expedition. The objective is clear: to reach Surat in the shortest possible time, assess the situation there accurately, gather the information required for the expedition, and return safely. The task concerns an important trading centre located deep within the Mughal Empire. It is therefore essential to gather as much accurate and varied information as possible before setting out.

Now, you are about to set out on a scouting operation as an intelligence agent. What information will you need to gather? From whom might you obtain it? How might you obtain it? How will you determine whether the information you have gathered is accurate and reliable? If information obtained from different people or sources differs, which information will you accept? Finally, how will you present all this information to Maharaj so that he can make the right decisions based on it?

You need to travel to Surat yourself to gather information. However, before setting out, you must decide exactly what information to collect, from whom to obtain it, and how to obtain it.”

When the situation is presented in this way, students begin to think by putting themselves in that role. Instead of simply trying to learn the textbook lesson on the expedition to Surat, they begin to approach the situation as intelligence agents preparing for an actual task. The question they ask themselves is no longer merely “What do I have to learn from this lesson?” but “What do I need to know to carry out this task successfully?”

This question becomes the starting point for group inquiry. Each group discusses the situation and prepares its own list of questions. What goods are traded in Surat? Who are the merchants? Who works for them? How is the city laid out? What goods are available in its different markets? Is a permit required to enter the city? Who issues it? Merchants from which communities and countries come here? Where is jakat (customs duty) collected? Where are private and government treasuries kept? What is the security system like? Which routes lead to Surat and back? Which is the shortest route? What difficulties might they encounter along the way?

In this way, students themselves identify the information they need and frame the questions that will guide their inquiry.

Next, each group is asked, “From whom will you obtain this information?” Students think of different people who might have useful information, such as a merchant’s accountant, a clerk, a porter, a boatman, a guide, a beggar, a darvesh (mendicant), a record-keeper at a customs post, a local shopkeeper, or a traveller. Through this exercise, they begin to realise that different people may possess different kinds of information.

The next question is, “How will you obtain this information?” Students suggest various methods: engaging in conversation, chatting with people, observing their surroundings, moving through the marketplace, talking to travellers, conducting reconnaissance, working at a particular place to understand the surroundings, or conducting business as a merchant.

At this stage, students become more active in the process. They begin to take on the roles of information seekers, questioners, and selectors of sources.

Next, each group is asked to review its list and consider two questions: “Which of this information do we need in numerical form? Which information do we need in descriptive form?” Through this exercise, students begin to understand the difference between quantitative and qualitative information through their own thinking and experience.

For example, they realise that numerical information is needed to determine the number of merchants, the quantity of goods, or the distance and time required for travel. On the other hand, qualitative information may be needed to understand the nature of the marketplace, merchants’ experiences, the atmosphere of the city, its security arrangements, or the forms of entertainment available.

Having identified what information they need and how it can be obtained, students now move on to experiencing the process through role-play. Some become merchants, accountants, porters, record-keepers at customs posts, travellers, or local residents, while others take on the role of intelligence agents gathering information. The students playing intelligence agents must ask questions, record the information they obtain, compare information gathered from different sources, and consider which information appears more reliable.

As they enact these roles, students realise that, during a covert operation, information cannot always be obtained by asking direct questions. It may have to be gathered indirectly through casual conversation and carefully framed questions, without arousing suspicion. They begin to appreciate how difficult and risky such work can be.

Through this experience, students move beyond merely identifying information to understanding the effort, judgement, and skill involved in gathering it. The textbook account of The reparations from Surat may simply state that Shivaji Maharaj set out from one place, reached Surat, took the treasure, and returned. Through the activity, however, students begin to experience the larger drama hidden behind these brief statements. The event comes alive for them, touching their own world of experience. The complexities of the historical event begin to touch their own world of experience.

Through such activities, students do not merely learn about a historical event. They place themselves in an imagined situation from the past: working as intelligence agents for Chhatrapati Shivaji Maharaj before the expedition to Surat. They think through the questions they would need to ask, the information they would need to gather, and the decisions they would need to make. In doing so, they begin to approach the past as researchers rather than as readers of a textbook.

This is a historical thought experiment—an exercise in using imagination and reasoning to explore how people might have gathered information and acted in a particular historical situation. Students move through a concise sequence of inquiry: framing questions → gathering and recording information → comparing sources and checking reliability → drawing conclusions → presenting findings to support decisions.

The activity naturally leads to further questions: “How will we determine which information is true and reliable?” If different sources provide different accounts, which will we accept? How will we verify the information? Finally, how will we present it to Maharaj so that it helps him plan the expedition and make decisions during its course?



When teaching history, we often find that students can recall numbers and facts from a textbook but struggle to understand what they actually represent. They may remember that a treaty involved the surrender of a certain number of forts, that a large amount was paid as tribute, or that an army travelled a considerable distance over several days. But can they imagine the extent of the territory surrendered, the magnitude of the amount paid, the distance travelled, or the scale of the effort involved? Remembering a number is not the same as understanding what it represents.

While teaching history, we often present students with information about the clauses of treaties, the terms of agreements, the transfer of territories, tribute, or revenue. However, simply hearing this information or reading it in a textbook does not necessarily help students grasp its numerical values and scale. They need to form a mental picture of what these numbers actually represent.

Merely stating the numbers is not enough. Their context and scale need to be connected to students’ own experience. The extent of a territory can be compared with a familiar region; a travel distance can be shown on a map; the amount of revenue or tribute can be related to economic transactions of that period and the present day; and the number of soldiers can be compared with the size of a group familiar to students. In these and many other ways, students can build a mental picture of a historical event.

Such visualisation is not limited to numbers. Historical information can be represented in numerical, descriptive, pictorial, and cartographic forms. Statistics can be presented in tables or graphs. The conditions of a particular historical period can be understood through descriptions and represented through pictures, diagrams, and sketches. Events that unfolded in sequence can be plotted on maps, and the routes they followed can be traced. Through these activities, students can develop a clearer understanding of historical events.

For example, while studying the Treaty of Purandar (1665), students can mark on a map the forts that Chhatrapati Shivaji Maharaj had to surrender under the treaty, along with the territories associated with them. They can examine the geographical extent of these territories and compare them with the territories associated with the forts that remained with him.

Similarly, while studying the Dandi March (1930), students can trace the approximately 390-kilometre journey from Sabarmati Ashram to Dandi on a map. They can then create a visual representation of the distance covered each day and the number of satyagrahis who participated in the march.

Thus, the ability to visualise historical information through different forms of representation, while understanding its nature, scale, extent, and interrelationships, is an important competency in learning history. Rather than merely memorising historical information, students need to understand its context and form a clear mental picture of what it represents. This is an important part of learning history.

An important skill that emerges through this process of learning history is information handling—finding information, identifying its sources, verifying it, classifying it, analysing it, and using it in the appropriate context. While learning history, we do not merely acquire information about people and events of the past. We also learn how to interpret information obtained from different sources, assess its reliability, and draw conclusions on the basis of the available evidence.

For example, while studying the Dandi March, students may encounter information about its route, distance, duration, and participants in a textbook, on a map, or in photographs and accounts of the march. They can compare these sources, check whether the information is consistent, trace the route on a map, and organise relevant details in a table or timeline. Through this process, they begin to understand not only what happened, but also how historical information can be examined and used to understand an event.

While learning history, students do not merely acquire information about people and events of the past. They also learn to interpret information from different sources, assess its reliability, and draw conclusions on the basis of available evidence.

In today’s information age, this ability has become even more important for the study of history. Information may come from books, maps, letters, inscriptions, pictures, oral accounts, newspapers, museum objects, or digital media. Each source has its own characteristics and limitations. Therefore, while teaching history, instead of merely providing students with information, it is essential to let them experience the process of handling information, examining it critically, and using it to build a mental picture of the past.

We cannot travel back through time in a time machine and experience historical events directly. However, the power of imagination can help us understand their scale, nature, and context. Using available historical information, numbers, maps, pictures, and different sources, we can help students build a vivid mental picture of the past.

In this way, beginning with a single historical event, students gradually experience the different stages of historical inquiry: identifying sources, exploring methods of gathering information, distinguishing between quantitative and qualitative information, assessing reliability, verifying evidence, analysing information, and presenting findings. Through such group activities, students experience why learning history involves more than simply acquiring information; it also requires engaging with information thoughtfully and critically.

Through such learning experiences, history becomes more than information read from a textbook; it becomes a subject to be explored and understood. It is here that the competency of information handling begins to develop through students’ own experience of learning history.

In the present day, the use of data and data science in learning history can help students understand historical trends, changes, and interrelationships more clearly. Three important applications are understanding historical trends, visualising historical events, and quantitatively studying socio-cultural changes.

Data science makes it possible to interpret information from different historical sources in greater depth and detail. History should therefore not be viewed merely as a chronological account of events, but also as an opportunity to understand different aspects of human life. Data can help us study human life in its spatial, temporal, resource-related, and social contexts. By digitising, classifying, and analysing historical documents, data science can help uncover new evidence and interpretations for writing history. Analysing information about archaeological sites, the distribution of artefacts, and records of structures can help us understand ancient social life, trade, and urban planning. Similarly, analysing census records, economic statistics, and other numerical data can help trace social and economic changes in modern India. In this way, data science not only makes historical writing more evidence-based, but also gives students new tools to analyse historical information and interpret its meaning.

For example, Geographic Information Systems (GIS) can be used to map the expansion of the Maratha Empire and study the relationships among forts, mountain ranges, mountain passes, and important locations. Students can plot the forts on a map and examine their distribution in relation to the surrounding physical landscape. They can identify clusters of forts, observe their proximity to mountain passes and routes, and compare locations across different regions. They then can discuss questions such as: Why might forts have been located in these places? How could the surrounding landscape have influenced movement, communication, and control over territory? What further information would they need before drawing conclusions? This can help students understand how geographical conditions influenced administration and power relations.

Similarly, by comparing census records and other statistics from different periods, students can study long-term changes in population, migration, urbanisation, and epidemics.

Data can also be used to study the distribution of resources and power relations in history. For example, mapping data on land revenue, agricultural production, or land ownership can make the economic conditions and patterns of social inequality across different regions more visible. In this way, studying the interrelationships among space, time, resources, and social power can lead to a more comprehensive understanding of complex historical processes.

Such activities make it clear that the study of history is not limited to the history textbook; it is interdisciplinary in nature. Mathematics and statistics help students understand numerical data; geography and cartography help them explore the spatial extent of events and the relationships between places; while computer science and data science enable them to analyse and visualise large volumes of information. Drawing on these different disciplines helps students make better sense of historical information. History teaching can therefore provide students with opportunities to integrate knowledge from different subjects and understand and interpret history on the basis of evidence.

The ability to understand the scope, nature, and interrelationships of historical information and to visualise it through different forms of representation is thus an important competency in learning history. A variety of classroom activities can be designed to develop this ability. These may include preparing tables and graphs from historical data, plotting historical events on maps, comparing information from different sources, converting information into visual representations, and investigating historical changes using digital data. For example, students can prepare graphs showing changes in India's population using census data, mark the major centres of the Revolt of 1857 on a map, compare different sources relating to the Jallianwala Bagh massacre, visually represent the route and duration of the Dandi March, or study the expansion of the Maratha Empire using digital maps.

Through such activities, students develop the ability to handle and interpret historical information. This involves identifying sources, gathering and verifying information, analysing and comparing evidence, recognising patterns and relationships, and presenting interpretations supported by evidence. Moving beyond memorising historical facts, students learn to investigate how events unfolded, understand their context, and draw conclusions from the available evidence.

Through such activities, students become more than collectors of information. They become historical investigators who can visualize, analyse information, interpret its meaning, and present their findings. Developing the ability to handle information while teaching and learning history means not only helping students understand the past, but also cultivating the habit of thinking on the basis of evidence.
