Julian date · ≈ Jul 4 on our calendar
In the final civil war of the Tetrarchy, Constantine defeated his co-emperor Licinius in a great battle at Adrianople in Thrace.
Background
By 324 Constantine ruled the West and Licinius the East. Relations had broken down, and Constantine invaded Licinius' territory with a large army.
The first major clash came at Adrianople (modern Edirne). Licinius lost and fell back on Byzantium; after a second defeat at Chrysopolis in September he surrendered, leaving Constantine sole emperor.

Fields & crops
Harvest finished in the uplands; threshing and storage, stubble burned or grazed, and the first ploughing of fallow per Columella 11.2. Cato advises that olive groves be hoed and vines tied in summer, and that the threshing floor be ready before grain is brought in per Cato, Agr. 2, 91.
Courts & law
Courts sat less during the Ludi Apollinares (6–13 July); much elite business paused as senators left the hot city late Republic.
Senate & politics
Renamed from Quintilis in 44 BC for Julius Caesar, born in this month. Republican consular elections were often held in July late Republic. Caesar was born on 12 or 13 July disputed: sources differ on the day; after his death the month was renamed in his honour by a law of Mark Antony in 44 BC per Macrobius 1.12.34.
Military
Peak campaign season. On 15 July the equites paraded through Rome (transvectio equitum), revived by Augustus per Suetonius, Aug. 38.
Festivals & religion
Ludi Apollinares (6–13 July), founded during the war with Hannibal; the Poplifugia (5 July); the Lucaria in sacred groves (19 and 21 July); Neptunalia (23 July) with leafy shelters against the heat per Varro and Festus.
Daily life
Water was precious: Rome's aqueducts fed public fountains, from which most people carried water up the stairs of their apartment blocks per Frontinus, De aquis. Food spoiled quickly; those without kitchens bought cooked food at taverns and street stalls. Graffiti at Pompeii record prices for bread, wine and oil, and rents for rooms per Pompeian inscriptions. Martial jokes that he lives up three tall flights of stairs, a common lot for renters satire, Martial 1.117. The well-off escaped to villas; the poor had no such option.
