The 2016 PSOE crisis was a political conflict within the Spanish Socialist Workers' Party (PSOE), starting on 26 September 2016. Long-standing discontent with party Secretary General Pedro Sánchez and the combination of a series of circumstances resulted in a party revolt to force Sánchez's dismissal on 28 September, in an episode lasting until 1 October colloquially dubbed by some media and journalists as the "war of the roses". The ensuing power vacuum and Sánchez's replacement by an interim managing committee, coupled with the party's turn to allow a PP minority government after a 10-month deadlock on government formation and the resulting worsening of relations with its sister party in Catalonia, the PSC, triggered a crisis of a scale unprecedented in the party's 137 years of existence
