From mid 1950, the process of dismantling and undermining autonomy took much form. To mention a few in 1955 large numbers of Shoans came to occupy the federal offices in Asmara and Massawa, and Ethiopia continued the process of dismantling the Eritrean government apparatus and Amharic was made the national language of Eritrea 1956, which was also rejected by the UP. The Ethiopian government further escalated intimidation against outspoken members of the Eritrean Assembly for violation of federal laws. This angered the assembly members. During this period the Ethiopian government also banned trade unions, closed many Eritrean industries, Eritrean workers were transferred to the capital city of Ethiopia, Addis Ababa(Pateman, 990:17). On the other hand some Ethiopian settled in the Eritrean towns.
