A Nov., 2006, accord called for the rebels to join the government and assemble in camps and place their weapons under UN supervision, and the following month an interim constitution under which the monarch was not head of state was agreed to. The question of the ultimate abolition of the monarchy was left to a constituent assembly that would be elected in 2007. Human-rights groups accused the rebels, however, of continuing to engage in extortion and conscription. In Jan., 2007, the rebels joined the interim parliament and the interim constitution came into effect; in April they joined a new interim government. Although some 31,000 rebels were in camps by late February, far fewer numbers of weapons had been sequestered. Also in January, long-simmering resentment of the native peoples of the Terai, known as Madhesis, led to protests and violence in S Nepal as the Madhesis pressed their demands for autonomy for the Terai. Although the government subsequently reached an agreement with the Madhesis, violence in the region continued throughout the year.
The government and the Maoists agreed to hold elections for the assembly in late 2007, and in June, 2007, parliament passed a constitutional amendment giving it the power to abolish the monarchy. The government later voted to nationalize the royal palaces and other royal property. The rebels withdrew from the government in Sept., 2007, demanding the monarchy be abolished before any elections, and the assembly elections were subsequently postponed into 2008. In Dec., 2007, the parliament voted to abolish the monarchy and establish a republic in Apr., 2008, after the constituent assembly elections; the Maoists then returned to the government.
