Tiberius Sempronius Gracchus was a Roman politician and reformer who lived in the 2nd century BC. He is known for his attempts to address the social and economic issues facing the Roman Republic, particularly the plight of the landless poor. Gracchus proposed land reforms and other measures to improve the lives of the lower classes, but his efforts were met with opposition from the Roman Senate and ultimately led to his violent death. Gracchus is remembered as a champion of the people and a symbol of the struggle for social justice in ancient Rome.
