[2] HADITU was founded in July 1947 through the merger of two communist factions, the Egyptian Movement for National Liberation and Iskra.
[9] In early 1948 Curiel presented the paper "The Line of National and Democratic Forces" to the HADITU Central Committee, a document that became an important point of reference in the organization.
One of the first groups to break away was the Revolutionary Bloc, led by Shudi Atiya ash-Shafi (He had left after not being included in the HADITU Central Committee as the movement was reorganized.
In April 1948 two HADITU splinter groups, Toward a Bolshevik Organization and Voice of the Opposition, merged to form the Egyptian Communist Organisation.
[13][14] Leaders of Gat included Issamuddin Jilal, Ahmed Taha, Ismail Jibr, Salah Salma and Ehia al-Mazsi.
HADITU was the most effective political force in the workers movement at the time, playing a leading role in various trade unions.
While Curiel formally remained a HADITU Central Committee member, he no longer played any role in the decision-making of the organization.
[17] After the executions of the two labour leaders, HADITU and non-communist trade unionists agitated in the working-class neighbourhoods of Alexandria and Kafr Dawar (in vehicles, with loudspeakers, borrowed from the army), but called on workers to remain calm.
The support to the government after the Kafr Dawar crack-down decreased HADITU influence in the labour movement, and internal rifts developed between the party and its trade union cadres.
[21] In the same year Joyce Blau, who had functioned as the courier between Curiel's Rome Group and the party in Egypt, was arrested.
In September 1952, the French communist daily L'Humanité published an article accusing Curiel of having had contacts with a Trotskyist informer during the Second World War.
When HADITU attempted to conduct unity discussions with other communist factions, the issue of Curiel's membership (being tainted by the accusations in L'Humanité) became a stumbling block.
