A decision of 9 August 1963, approved by a referendum of 15 December 1963, gave the territory a measure of autonomy and the administrative promotion of a 'moderate' group, the  (MUNGE). This proved a feeble instrument, and, with growing pressure for change from the UN, Madrid was gradually forced to give way to the currents of nationalism. Two General Assembly resolutions were passed in 1965 ordering Spain to grant independence to the colony, and in 1966 a UN Commission toured the country before recommending the same thing. In response, the Spanish declared that they would hold a constitutional convention on 27 October 1967 to negotiate a new constitution for an independent Equatorial Guinea. The conference was attended by 41 local delegates and 25 Spaniards. The Africans were principally divided between Fernandinos and Bubi on one side, who feared a loss of privileges and 'swamping' by the Fang majority, and the Río Muni Fang nationalists on the other. At the conference the leading Fang figure, the later first president Francisco Macías Nguema gave a controversial speech in which he claimed that Adolf Hitler had 'saved Africa'. After nine sessions the conference was suspended due to deadlock between the 'unionists' and 'separatists' who wanted a separate Fernando Pó. Macías resolved to travel to the UN to bolster international awareness of the issue, and his firebrand speeches in New York contributed to Spain naming a date for both independence and general elections. In July 1968 virtually all Bubi leaders went to the UN in New York to try and raise awareness for their cause, but the world community was uninterested in quibbling over the specifics of colonial independence. The 1960s were a time of great optimism over the future of the former African colonies, and groups that had been close to European rulers, like the Bubi, were not viewed positively.
