The Roman economy was primarily based on agriculture, with most people working as farmers. They grew crops like wheat, barley, and olives, which were essential for food and trade. The use of slaves was common, providing labor for large estates known as latifundia. Trade also flourished, with goods exchanged across the vast Roman Empire through a network of roads and sea routes. In addition to agriculture, the economy included crafts and manufacturing. Artisans produced pottery, textiles, and metalwork, while markets in cities like Rome facilitated commerce. Currency, such as the denarius, helped standardize trade, making it easier for people to buy and sell goods.
