Asterix and Caesar’s Gift is the twenty-first volume of the Asterix comic book series, by René Goscinny (stories) and Albert Uderzo (illustrations). It was the first Asterix adventure that was not published in serial form in Pilote magazine prior to its publication as a book.

Having completed twenty years of service in the Roman Army, veteran legionaries Tremensdelirius and Egganlettus await their honesta missio (Latin: honorary discharge) in the morning, but that night a drunk Tremensdelirius insults Julius Caesar and gets arrested. When Caesar is informed of Tremensdelirius’s mishap, he decides to play a practical joke on him. Caesar awards a “special gift” to Tremensdelirius: Asterix’s village in Armorica, the only territory of Gaul not yet conquered by the Roman legions. Tremensdelirius sees little merit in a gift he cannot drink and winds up exchanging the gift for wine and food at an inn in Arausio, owned by Orthopaedix.

Orthopaedix, his wife Angina and daughter Influenza arrive at the village only to be disappointed to find it already inhabited, and that Caesar does not own the village at all (making the gift worthless). With no place to go, Angina berates her husband for selling their inn to travel to Armorica. Vitalstatistix overhears the conversation and decides to offer Orthopaedix a building to open a new inn. Obelix soon has a crush on Influenza, while Geriatrix doesn’t welcome Orthopaedix and his family, regarding them as outsiders. The villagers attends the new inn’s opening night, but Vitalstatistix’s wife Impedimenta and Angina start arguing about who owns the village. A fight starts ensues and the inn is trashed as a result.

The next morning, a bruised Orthopaedix is ready to leave and return to Lutetia, his hometown, but Angina wants to have revenge on Impedimenta and makes a claim to the leadership of the village on behalf of her husband. Vitalstatistix, shocked, has Cacofonix obtain an opinion poll of the villagers and learns that aside from Geriatrix, the villagers don’t really care, until Vitalstatistix makes a few remarks that offends some of the villagers, making them go to the other side. A political race starts, and Geriatrix thinks Vitalstatistix is weak and tries to stand for Chief himself. Asterix becomes worried that internal conflict could benefit the Romans. Meanwhile, Tremensdelirius arrives at the village to visit Orthopaedix, explains that since their last meeting he unsuccessfully tried all kinds of trade and he wants his land back, since he is in fact not allowed to sell the land. When the family refuses, he draws his sword. Asterix arrives, and the two fight, with Asterix winning. Influenza is impressed, while Tremensdelirius, swearing revenge, goes to the Laudanum Roman camp and finds his old friend Egganlettus serving as an aide-de-camp under the local centurion (as he found retirement boring and signed up for another 20 years). With his support, Tremensdelirius makes an official request to the centurion to restore his land. The centurion is reluctant to face the Gauls, but the veterans threaten to report him to Caesar, and he agrees to prepare a military attack with the new weapons they have.
