297 BC is a year of the pre-Julian Roman calendar and belongs to the late third century BC, a period of political realignment across the Mediterranean and beyond. At the time people did not use the modern "BC" label; Roman records dated years by magistrates or local systems. Modern historians place events recorded in those systems in 297 BC to build a synchronized chronology.
Overview
Across the Mediterranean the third century BC was a time of consolidation and conflict. Rome was extending its influence within Italy, while the successor states that emerged after Alexander the Great's death continued to jockey for territory and dynastic advantage. Farther east, regional states in China remained in the long-running Warring States period.
Political and military developments
- Roman Republic: Rome was engaged in protracted campaigns on the Italian peninsula, part of the broader series of Samnite Wars that shaped Roman dominance in Italy. Military operations, alliances and sieges during this era gradually increased Roman control beyond Latium and Campania.
- Hellenistic world: One of the clearer markers for the year is the death of Cassander, king of Macedon, whose passing triggered succession disputes and instability in Macedonia. That instability opened opportunities for other Diadochi (Alexander's successors) to intervene and for rival claimants to press their advantages.
- Other regions: In the eastern Mediterranean and Near East, successor kingdoms managed local revolts and border tensions. In East Asia, the Warring States period in China continued to see rivalry among powerful states vying for supremacy.
Because surviving records are uneven, many local events of 297 BC are known only through later historians or fragmentary inscriptions. Chronological reconstruction relies on cross-referencing Roman consular lists, Greek accounts, and archaeological evidence.
Dating and historiography
The year is commonly described using the modern BC system, but contemporaries used regnal years, city-era counts or consular dating. For Roman chronology the pre-Julian calendar and the practice of identifying years by the two serving consuls were standard; modern readers can consult specialized works and databases for synchronized lists and conversions. For general background on Roman calendrical practice see resources on the pre-Julian Roman calendar.
As with many ancient years, 297 BC is best understood as a node in longer processes—Roman expansion in Italy, the fragmentation and realignment of the Hellenistic kingdoms, and continuing state competition in East Asia—rather than a moment defined by a single, universally recorded event.
