The two parliamentary groups were non-influential during the early years of the Republic, dominated by the monarchist Moral Order coalition of Patrice MacMahon, but after the failure of a return to the monarchy and after the legislative elections of 1876 the moderate and radical republicans gained 193 and 98 seats in the Chamber, respectively.
From this time, the republicans maintained strong majorities in the French Parliament and were pejoratively called Opportunists by their detractors for their aptitude to gain the popular consensus in spite of any ideology.
To prevent the creation of a socialist state, the two radical and moderate republicans spirits decided to cooperate and form common governments despite the personal antagonism between Grévy and Gambetta, who died in 1882.
However, Grévy also signed the so-called Lois scélérates ("villainous laws") that restricted the freedom of the press and France started a colonial expansion in Africa, creating protectorates in Madagascar and Tunisia.
The revanchist ideas were strong in the France of the Belle Époque and with the scandals involving the republican governments there was a rise of the nationalist party led by General Georges Boulanger.
His appointment was a strategy of Prime Minister Goblet to pledge the nationalists, but after the fall of his cabinet he was replaced by Maurice Rouvier and the General was not reconfirmed.
Continuing to depict itself as leftist, the ANR was a conservative group opposing the income tax and strikes[23] that tried to defend the Republic from its reputed enemy Boulanger and used many banquets to finance his activities.
In the 1890s, the Moderate Republican parable ended as the Panama scandals of 1892 involved prominent Radical politicians like Clemenceau, Alfred Naquet and Léon Bourgeois,[24][25] granting a large victory to the ANR in the legislative elections the following year.
[27] Many Moderate Republicans joined the ADR, including Yves Guyot, Ferdinand Dreyfus (not linked with the Colonel), Narcisse Leven and David Raynal.
