A prominent example of how Digital Humanities and History intersect is the project titled Mapping the Republic of Letters. This project focuses on visualizing the intellectual exchange that took place in Europe during the Enlightenment period. Using Geographic Information Systems (GIS) and data visualization tools, the project maps out the correspondence networks of influential Enlightenment thinkers such as Voltaire, John Locke, and others.

Who, Where, When
- Who:
This refers to the individuals involved in the intellectual exchanges during the Enlightenment, such as philosophers, scientists, and thinkers. Specifically, the project focuses on prominent figures like Voltaire, John Locke, Montesquieu, and other intellectuals of the Enlightenment who corresponded through letters, contributing to the exchange of ideas that shaped European thought. - Where:
The correspondence mapped in the project occurred primarily across Europe. Key locations include major intellectual hubs such as Paris, London, Amsterdam, and other cities where scholars, philosophers, and political thinkers lived or traveled. The mapping aspect shows how ideas were communicated across different regions, tracking the movement of letters and the spread of knowledge through Europe. - When:
The timeline for the project focuses on the Enlightenment period, roughly spanning the late 17th century to the early 19th century (specifically around 1650–1800). This was a time when intellectuals engaged in debates about reason, science, philosophy, and governance, significantly influencing modern thought. The project’s historical context emphasizes the flow of ideas during this period.
