The elections to the Convention were by almost universal suffrage, but indifference or intimidation reduced the voters to a small number. Many who had sat in the National, and many more who had sat in the Legislative Assembly were returned. The Convention met on the 20th of September. Like the previous assemblies, it did not fall into well-defined parties. The success of the Jacobins in overthrowing the monarchy had ended their union. Thenceforwards the name of Jacobin was confined to the smaller and more fanatical group, while the rest came to be known as the Girondins. The Jacobins, about 100 strong, formed the Left of the Convention, afterwards known from the raised benches on which they sat as the Mountain (q.v.). The Girondins, numbering perhaps 180, formed the Right. The rest of the House, nearly 500 members, voted now on one side now on the other, until in the course of the Terror they fell under the Jacobin domination. This neutral mass is often termed the Plain, in allusion to its seats on the floor of the House. The Convention as a whole was Republican, if not on principle, from the feeling that no other form of government could be established. It decreed the abolition of monarchy on the 21st of September. A committee was named to draft a new constitution, which was presented and decreed in the following June, but never took effect and was superseded by a third constitution in 1795. The actual government of France was by committees of the Convention, but some months passed before it could be fully organized. Jacobins and Girondins.
