Eugène Bonaventure Jean-Baptiste Vigo (known as Miguel Almereyda; 5 January 1883 – 14 August 1917) was a French journalist and activist against militarism.

He founded and wrote in the newspaper La Guerre sociale and the satirical weekly Le Bonnet rouge.

His father was engaged in trade, born in Saillagouse, and his mother Marguerite Aimée Sales was a seamstress from Perpignan.

He struggled to make a living but found friends in anarchist circles, including the slightly older Fernand Desprès, for which he became known to the police.

[2] Eugène Vigo was arrested in May 1900, ostensibly as an accessory in the receipt of stolen goods, but in fact for his anarchist activity.

After being released he found work with a photographer on the Boulevard Saint-Denis, and published his first article in Le Libertaire in which he described plans to attack the judge who had convicted him with a bomb.

[5] The Ligue antimilitariste was founded in December 1902 by the anarchists Georges Yvetot, Henri Beylie, Paraf-Javal, Albert Libertad and Émile Janvion.

[8] In the fall of 1905 Almereyda and Gustave Hervé plastered AIA posters all over Paris urging young men to resist conscription with violence if needed.

He was the leader of the "Liabeuf" affair, in which a large crowd demonstrated over the execution of a young cobbler, and a detective was killed.

During the railway strike of October 1910, Almereyda and Merle formed a group to organize sabotage and were arrested and imprisoned until March 1911.

[11] La Guerre Sociale steadily became less revolutionary and more a supporter of left-wing republican ideals to be achieved legally.

The journal, "organ of the Republican defense", was the sworn enemy of the right-wing monarchist political movement Action Française.

[13] With the outbreak of war Le Bonnet Rouge and La Guerre Sociale accepted the need to fight to defend the country.

After visiting the battlefields, Almereyda became convinced of the horrors of war, which he discussed in his articles, but also of the need to defend the republic and the government against extreme right-wing forces.

[15] Almereyda began to use Le Bonnet Rouge to advance various business interests, using the money for his personal use and to support the paper.

It made much of US President Woodrow Wilson's effort to have the belligerents declare their goals in preparation for a peace conference.

[17] In July 1917 the business administrator of Le Bonnet Rouge was arrested on his return from a trip to Switzerland, and was found to have a check on a German bank account for 100,000 francs.
