During periods of Franco's temporary incapacity in 1974 and 1975, Juan Carlos was acting head of state. On 30 October 1975, Franco gave full control to Juan Carlos. According to declassified CIA reports, during this time Juan Carlos secretly acquiesced and arranged with Moroccan king Hassan II the terms of the so-called Green March, the partial invasion of the Spanish Sahara by Moroccan civilians, followed by the Madrid Accords handing over the control of the territory to Morocco and Mauritania.
