The Basque Country remained, for the better part of this period, in a state of political turbulence. Suárez granted a multi-stage amnesty for numerous Basque political prisoners, but the confrontations continued between local police and protesters. The separatist group ETA, which in the middle of 1976 had seemed open to a limited truce after Franco's death, resumed armed confrontation again in October. The time from 1978 to 1980 would be ETA's three deadliest years ever. However, it was between December 1976 and January 1977 that a series of attacks brought about a situation of high tension in Spain.
