After the successive trails to establish a liberation movement in the country, Eritreans residing abroad formed a new clandestine liberation movement in Port Sudan, Sudan. Osman Mohammed Said Nawed, Idris Mohammed Al-Hassen, Osman Mohammed Osman, Taher Fedab, Mohammed Faki Mahmoud and Saleh Eyed were few of those who established the Eritrean Liberation Movement (Haraka).

Customary laws have qualities that outweigh modern laws in terms of depth, intensity and details of legal procedures and particularly in moral responsibilities. Before the introduction of modern law, the Eritrean societies used to settle matters depending on already set customary laws that were functional among different populations. Most of them have been orally transferred form one generation to another. Of course some of them are documented in publications to date. The depth of the philosophy and their magnitude makes one admire the subtle and pragmatic ways of peacefully settling matters of different kinds.  Of the many rich Eritrean customary laws, Mada-customary law of the Afar ethnic group, has been preserved in the written form through the initiatives taken to collect materials form the memories of Afar elders.

On the first election to choose members of the Eritrean Assembly, Asfaha Weldemicheal was elected as the governor of the country, but after one year a second election was held to choose additional members of the assembly. Collaborators of the Ethiopian government made it impossible for the nationals to get elected; they even fired former members of the assembly like Sheikh Ibrahim Sultan and Omer Hakito and imprisoned others who opposed the intervention of the Ethiopian government in the country’s affairs. Later, Omer Hakito was returned to the assembly by the verdict passed in the Eritrean court. As a result of the oppression and devious actions of the collaborators of the Ethiopian Government, majority of the elected members of the assembly were from the Unionist Party. This was mainly done by Dimetros and the help of the then Police Commander, Tedla Oqbit.

Opposition Within The Eritrean Assembly

As previously stated, majority of the assembly members were supporters of Ethiopian government but after the establishment of federation and the continuous oppressions from the Ethiopian government, most of those individuals began realizing the tyranny of the Ethiopian government and started opposing it.

After the official declaration of Eritrean constitution by the country's newly formed assembly: it was passed to the Emperor Haileselasie of Ethiopia for approval where he signed it for the implantation which also declared the official annexation of Eritrea with Ethiopia. This was done in September 11, 1952.  And just before the official annexation of both countries Ras Endargachew Mesay, son in law of Emperor Haileselasie with his wife Tenanwerke Haileselasie was send as a representative of the emperor to Eritrea and resided in the capital’s presidential palace.

The Establishment an Eritrean Government
As previously mentioned the Eritrean people were against the idea of federation. Ideally, in a state of federation, the people’s choice should have been considered but in the case of Eritrea, the people's choice was not put into consideration. Due to the constant pressure from the British administrators, and the chaos and instability in the country the people of Eritrea were forced to accept the federation.
