First, Second and Third Veientine Wars

The First Veientine War (483-474 B.C.) was the first of three clashes between Rome and her nearest Etruscan neighbour, the city of Veii.
The Second Veientine War (437-434 or 428-425 B.C.) was fought for control of the crossing over the Tiber at Fidenae, five miles upstream from Rome.
The battle of the Anio (437 or 428 B.C.) was a Roman victory early in the Second Veientine War that was won after Lars Tolumnius, king of Veii, was killed in single combat
The battle of Nomentum (435 or 426 B.C.) was a Roman victory over a combined army from Veii and Fidenae that was followed by a successful Roman attack on Fidenae, and possibly by the end of the Second Veientine War.
The siege of Fidenae (435 or 426 B.C.) saw the Romans capture the town only five miles upstream on the Tiber and eliminate the last Veientine enclave on the right bank of the Tiber.
The Third Veientine War (405-396 B.C.) saw the Roman Republic finally capture and destroy their closest rival, the Etruscan city of Veii, after a siege that lasted for ten years
The ten year long siege of Veii (405-396 B.C.) was the main event of the Third Veientine War and saw the Romans finally conquer their nearest rival, the Etruscan city of Veii.
