Why did Pompey seek land for his veterans?

Pompey the Great sought land for his veterans primarily to fulfill his obligations to the soldiers who had served under him and to secure his own political standing. As a Roman commander, Pompey relied on the loyalty of his troops, and providing them with land was a standard way to ensure their post-service livelihood and maintain his influence over them as his clientelae.12

However, after his return from the East, Pompey faced significant opposition from the Optimates, an inner ring of nobles who sought to diminish his power by rejecting his demands for land grants for his veterans and refusing to ratify his eastern settlements. This political resistance eventually led Pompey to form the First Triumvirate with Julius Caesar and Marcus Licinius Crassus. Once Caesar became consul in 59 BCE, he successfully forced through land bills, including the appropriation of public lands in Campania, to satisfy the needs of Pompey’s discharged troops.23
