The 1975 coup d'état in Chad that terminated Tombalbaye's government received an enthusiastic response in the capital N'Djamena. Félix Malloum emerged as the chairman of the new Supreme Military Council (Conseil Supérieur Militaire or CSM), and the first days of the new regime were celebrated as many political prisoners were released. His government included more Muslims from northern and eastern Chad, but ethnic and regional dominance still remained very much in the hands of southerners. Economic policies The successor government soon overturned many of Tombalbaye's more odious policies. For example, the CSM attempted to distribute external drought relief assistance more equitably and efficiently, devised plans to develop numerous economic reforms, including reductions in taxes and government expenditures, and abandoned some of the more oppressive measures used to encourage cotton production. Political control and opposition Neither reformers nor skilled administrators, the new military leaders were unable to retain for long the modicum of authority, legitimacy, and popularity that they had gained through their overthrow of the unpopular Tombalbaye. The expectations of most urban Chadians far exceeded the capacity of the new government, or possibly any government, to satisfy them. Moreover, it soon became clear that the new leaders, who were mostly southern military officers, saw themselves as caretakers rather than innovators, and few of Tombalbaye's close associates were punished. Throughout its tenure, the CSM was unable to win the support of the capital's increasingly radicalized unions, students, and urban dwellers. The government suspended the National Union of Chadian Workers (Union Nationale de Travailleurs du Tchad or UNTT) and prohibited strikes, but labour and urban unrest continued from 1975 through 1978. On the first anniversary of the formation of the CSM, Malloum was the target of a grenade attack that injured several top officials and spectators. A year after that, in March 1977, the CSM executed summarily the leaders of a short-lived mutiny by several military units in N'Djamena. Foreign relations and growing dissension The fundamental failures of Malloum's government, however, were most evident in its interactions with France, Libya, and FROLINAT. In his first few months in office, Malloum persuaded a few eastern rebel elements to join the new government. In the north, the derde (Oueddei Kichidemi) returned from exile in Libya in August 1975. But his son, Goukouni Oueddei, refused to respond to his entreaties or those of the government and remained in opposition. When the Command Council of the
