CO-HABITING THE MEDITERRANEAN WORLD:
Political, Economic, and Cultural Diplomacy Between Christians and Muslims (15th – 19th centuries)
On March 18 and 19, 2025, the Institut d'études avancées in Nantes will host a research workshop led by former fellows Florence Ninitte and Ferenc Toth.
The goal of this workshop is to bring together specialists from various fields – historians, literary scholars, geographers, and archaeologists – to analyze and debate the complexity of diplomatic relations between Christian and Muslim powers during a period marked by profound upheavals, from the rise of the Ottoman Empire to the end of the 19th century.
Organized in collaboration with international experts, this event will focus particularly on the evolution of conflicts, alliances, commercial and cultural exchanges, as well as the diplomatic and economic networks that, despite geopolitical tensions, facilitated the creation of spaces for interaction and cohabitation in the Mediterranean world.

Tuesday, March 18 (open to the public upon registration)
Wednesday, March 19 (open to the public upon registration)
Centre des Archives Diplomatiques in Nantes (Tuesday, March 18)

An Interdisciplinary Look at Diplomatic Issues
Centered on exchange and interdisciplinarity, the workshop offers a reflection around two main themes:
- Relations between Christian and Muslim Powers in the Face of International Rivalries: Analysis of diplomatic actors (ambassadors, consuls, agents, etc.) and their roles in negotiations, strategic cooperations (capitulations, peace treaties), and the influence exerted by ethnic and religious minorities in the context of 15th and 16th-century conflicts.
- The Impact of Diplomatic Exchanges: Study of the movement of people, objects, knowledge, technologies, and ideas, as well as cultural and scientific transfers facilitated by diplomatic networks.
The speakers will examine how these dynamics contributed to the emergence of new disciplines while also playing a role in the modernization of diplomatic institutions such as embassies, consulates, and trading posts.
The workshop will be organized around three thematic working sessions, accompanied by lectures that will highlight concrete case studies and new perspectives on Christian-Muslim relations in the modern era.
A key moment of the workshop will be the visit to the Centre for Diplomatic Archives of Nantes, allowing researchers to access valuable historical sources in order to explore large-scale collective projects, such as preparing an application for a European grant, such as an ERC grant.
