As part of its mission to show the enormous diversity and interest of work on the heritage of the Napoleonic periods, the Fondation Napoléon has been a partner in events organised by a broad range of institutions (museums, public and private organisations, companies and associations). It also supports the development French national museums dedicated to the history of the two Empires. Furthermore, the Fondation forms partnerships with universities and research centres (or indeed simply groups of enthusiasts) the world over.

The Fondation Napoléon supports both morally and financially the activities of the Association du Souvenir Napoléonien, French society of Napoleonic history, and its four thousand members in France and several hundred international members. Every year the Fondation spends more than half of its patronage budget on this alone. The Fondation also entirely funds the Revue du Souvenir Napoléonien, a history magazine published six times a year and which publishes articles by some of the best specialists of the history of the two Empires. This magazine is sent to all the members of the Souvenir Napoléonien.
