While the resort was busy with families enjoying the weekend, Roger Haywood spouted abuse during a protest on August 3.
Police said he encouraged others to be violent and assaulted police officers who were there to keep Blackpool safe.
He also led a mob through the resort and beckoned them to breach the police cordon, “intent on disorder”.
The 41-year-old, of Yew Tree Road, Blackpool, was jailed for two years and six months on Friday.
He was sentenced for offences of violent disorder and two counts of assaulting an emergency worker.
