what does it mean to send someone to coventry
Send to Coventry To send someone to Coventry is an English idiom meaning to deliberately ostracise someone. Typically, this is done by not talking to them, avoiding their company, and acting as if they no longer exist. Victims are treated as though they are completely invisible and inaudible. The Coventry in the phrase is the cathedral city in the West Midlands.
The Song of Roland Charlemagne's army is fighting the Muslims in Spain. They have been there for seven years, and the last city standing is Saragossa, held by the Muslim King Marsile. Threatened by the might of Charlemagne's army of Franks, Marsile seeks advice from his wise man, Blancandrin, who councils him to conciliate the Emperor, offering to surrender and giving hostages. Accordingly, Marsile sends out messengers to Charlemagne, promising treasure and Marsile's conversion to Christianity if the Franks will go back to France.
