Since September 2018, two unprecedented social movements upraised in France: the yellow vests movement and the marches for climate. Both have carried massive mobilizations, rejected usual intermediaries, and heavily used social media. Both are long-term mobilizations and have profoundly shaken up the french political life.

Despite these important similarities on the form, the two movements are composed of different sociological categories, and were initiated on apparently opposed grounds, as the yellow vests movement has been sparkled by an opposition to the increase of the price of gas and the implementation of an ecological tax on it.

However, as of today, the two movements have strongly evolved in the direction of a convergence. I will present a chronology of this convergence, and some of the key elements that pushed for it.
