Roman military (107): Mariuss consulships

An institution that became a state, then a payroll problem Rome's military history is the history of who was a citizen, who was paid, and who could march on the city. The manipular legion and the Italian alliance system won the Mediterranean and broke at Cannae -- then recovered. Scipio Africanus is a name; the alliance is the structure.

Hannibal is on this page as the opponent who proved the structure, not as a romantic captain. Marius, the Social War (91-88 BCE), and Sulla's march on Rome are the dangerous lesson English textbooks compress as "the army became political." That sentence is a civil-war history, not a coup recipe -- see also the coups family for modern files.

Augustus regularised pay, length of service, and the Rhine-Danube idea of a frontier. Trajan's column is a propaganda object as well as a source. The navy (Misene and Ravenna fleets) is the under-taught half. No fort-design how-to; archaeology is evidence, not a field manual. Adrianople, Vegetius, and the fifth-century West are a payroll, recruitment, and politics crisis. The East continues -- a sequel, not a vanishing.
