The only great noble who rose was Henri, duc de Montmorenci, governor of Languedoc, and his defeat at Castelnaudary on the 1st of September 1632 was followed by his speedy trial by the parlement of Toulouse, and by his execution.
On the 21st of August 1715 he summoned all the preachers in the Cevennes and Lower Languedoc to a conference or synod near the village of Monoblet.
The scene of his labours for fifteen years was Languedoc, the Vivarais, and Dauphine.
Synods were held in 1718, 1723, 1726 and 1727; and in a remote spot in Bas Languedoc in 1 744 a national synod assembled - the first since 1660 - which consisted of representatives from every province formerly Protestant.
Some of these are on the south-west coast, in the Landes, as Carcans, Lacanau, Biscarosse, Cazau, Sanguinet; but more are to be found in the south and south-east, in Languedoc and Provence, as Leucate, Sigean, Thau, Vaccars, Berre, &c. Their want of depth prevents them from serving as roadsteads for shipping, and they are useful chiefly for fishing or for the manufacture of bay-salt.
