A man has been jailed for 15 months for uploading racist video clips on to YouTube.
Gareth Hemingway, 29, of Bognor Regis, earlier pleaded guilty to five offences under the Public Order Act at Leeds Crown Court.
The clips called for a "racial holy war" and were designed to provoke violence against ethnic minorities, particularly in Dewsbury.
When he was arrested, police found Nazi and racist memorabilia at his home.
The Crown Prosecution Service (CPS) said the material came to the attention of police when a journalist researching Dewsbury on the internet came across videos Hemingway, of Longford Road, had posted and reported them.
Racist imagery
The CPS said they included titles such as 'red, white and blue through and through' and 'Dewsbury needs help'.
They also featured racist references and imagery including an assault on a black man by a white man.
Stuart Laidlaw, reviewing lawyer for the CPS, said: "Gareth Hemingway decided to use the very public forum of YouTube to distribute videos of racist and inflammatory nature which he had edited, and which were designed to provoke violence against ethnic minorities, particularly those living in Dewsbury.
"They called for a 'racial holy war', described acts of violence and made supportive references to far right groups such as Combat 18 and Patriots of White European Resistance."
Mr Laidlaw added: "Freedom of speech carries with it responsibilities.
"Publishing something that is abusive and insulting and that is likely to stir racial hatred is against the law and the CPS will work with the police to prosecute robustly anyone who does so."
