How did Diocletian recruit soldiers for the Roman army?

Diocletian employed several methods to recruit soldiers and maintain the strength of the Roman army during his reign:

• Hereditary Service: The sons of soldiers were legally required to follow in their fathers' footsteps and enter military service.1
• Barbarian Recruitment: The army actively recruited barbarians, who enlisted either as individuals or as entire tribes.1
• Landowner Obligations: Landowners were mandated to provide either new recruits for the army or a corresponding sum of money to the state.1
• Municipal Assistance: Local municipal authorities were tasked with assisting in the supply of recruits as part of their administrative duties to the imperial government.1

These measures were part of a broader effort to increase the army's total strength and ensure the stability of the empire's borders.1
