When the Rising commenced, the French press did not have any journalists on the ground in Ireland and therefore they were not sure how widespread it was. This lack of real information is reflected in how they described the Rising. It was variously labelled a riot, skirmish, clash, revolt, and finally rebellion. When they had time to reflect on what had happened in Dublin, they had a more informed reading of the situation and it was no longer seen as just an attack on Great Britain, but a break for Irish independence.
The French daily newspaper Excelsior started to cover events in Dublin from as early as 30 April 1916. According to Clyde Thogmartin's The National Daily Press of France, Excelsior was France's "first photographically illustrated paper". It was started by Pierre Laffitte in 1910 with financial assistance from the controversial industrialist Basil Zaharoff. Excelsior was an innovative publication that used good quality photographs to report on the major news stories of the day. It reached its zenith in the 1930s and ran until 1940. Below, you can see some of the images that they published following the outbreak of the Rising, from the arrival of troops on the streets of Dublin, to the destruction of O'Connell Street (Sackville Street) and the execution of some of the leaders of the Rising.
