The Appian Way (Latin and Italian: Via Appia) was one of the earliest and strategically most important Roman roads of the ancient republic. It connected Rome to Brindisi, Apulia, in southeast Italy. Its importance is indicated by its common name, recorded by Statius:

The road is named after Appius Claudius Caecus, the Roman censor who began and completed the first section as a military road to the south in 312 BC during the Samnite Wars.

The Roman army depended for its success on the use of bases in which to prepare for retreat^{[citation needed]} and to refresh and re-equip afterwards. Bases allowed the Romans to keep a large number of soldiers in the field waiting for the opportunity to strike. However, the bases needed to be connected by good roads for easy access and supply from Rome. The Appian Way was used as a main route for military supplies since its construction for that purpose in the mid-4th century BC.

The Appian Way was the first long road built specifically to transport troops outside the smaller region of greater Rome (this was essential to the Romans). The few roads outside the early city were Etruscan and went mainly to Etruria. By the late Republic, the Romans had expanded over most of Italy and were masters of road construction. Their roads began at Rome, where the master itinerarium, or list of destinations along the roads, was located, and extended to the borders of their domain – hence the expression, "All roads lead to Rome".

Appian^{[pronunciation?]} of Alexandria (Ancient Greek: Ἀππιανός Ἀλεξανδρεύς, Appianós Alexandreús; Latin: Appianus Alexandrinus; ca. AD 95 – ca. AD 165) was a Roman historian of Greek ethnicity who flourished during the reigns of Emperors of Rome Trajan, Hadrian, and Antoninus Pius.

He was born circa 95 in Alexandria. He tells us, after having filled the chief offices in the province of Aegyptus (Egypt), he went to Rome circa 120, where he practised as an advocate, pleading cases before the emperors (probably as advocatus fisci), that in 147 at the earliest he was appointed to the office of procurator, probably in Egypt, on the recommendation of his friend Marcus Cornelius Fronto, a well-known litterateur. Because the position of procurator was open only to members of the equestrian order (the "knightly" class), his possession of this office tells us about Appian's family background.

His principal surviving work (Ῥωμαϊκά, known in Latin as Historia Romana and in English as Roman History) was written in Greek in 24 books, before 165. This work more closely resembles a series of monographs than a connected history. It gives an account of various peoples and countries from the earliest times down to their incorporation into the Roman Empire, and survives in complete books and considerable fragments. The work is very valuable, especially for the period of the civil wars.
