The father died when Tiberius was still a boy, and the two brothers grew up under the care of their mother, a noble and gifted lady. They early displayed remarkable talents. Tiberius, when old enough, went into the army, and served under his brother-in-law in the last Carthaginian campaign. He was first on the walls of the city in the final storm. Ten years later he went to Spain as quaestor, when he carried on his father's popularity, and by taking the people's side in some questions, fell into disagreement with his brother-in-law. His political views had perhaps already inclined to change. He was still of an age when indignation at oppression calls out a practical desire to resist it. On his journey home from Spain he witnessed scenes which confirmed his conviction and determined him to throw all his energies into the popular cause. His road lay through Tuscany, where he saw the large estate system in full operation--the fields cultivated by the slave gangs, the free citizens of the Republic thrust away into the towns, aliens and outcasts in their own country, without a foot of soil which they could call their own. In Tuscany, too, the vast domains of the landlords had not even been fairly purchased. They were parcels of the _ager publicus_, land belonging to the state, which, in spite of a law forbidding it, the great lords and commoners had appropriated and divided among themselves. Five hundred acres of state land was the most which by statute any one lessee might be allowed to occupy. But the law was obsolete or sleeping, and avarice and vanity were awake and active. Young Gracchus, in indignant pity, resolved to rescue the people's patrimony. He was chosen tribune in the year 133. His brave mother and a few patricians of the old type encouraged him, and the battle of the revolution began. The Senate, as has been said, though without direct legislative authority, had been allowed the right of reviewing any new schemes which were to be submitted to the Assembly. The constitutional means of preventing tribunes from carrying unwise or unwelcome measures lay in a consul's veto, or in the help of the College of Augurs, who could declare the auspices unfavorable and so close all public business. These resources were so awkward that it had been found convenient to secure beforehand the Senate's approbation, and the encroachment, being long submitted to, was passing by custom into a rule. But the Senate, eager as it was, had not yet succeeded in engrafting the practice into the constitution. On the land question the leaders of the aristocracy were the principal offenders.
