As a follow up question, where would they store their money. Did they have banks? If yes, who could deposit money there, like anyone or only rich people? If there were no banks did they have like a treasury room where they would store all their dough?

Im sorry if these questions are super basic but basically, could you explain me how money management went for rich people (not necesarry Roman citizens, but I guess all rich people in Rome were citizens)?

Thanks

As it still is today for Italy and Spain, large, massive estates for olive oil, wine and somewhat grain popped up to feed the burgeoning cities and to feed its army. It's hard to say how many gained their initial bit of land/ money, often soldiers would be given grants for a long period of service, but the elite maintained their wealth by having these large estates. The political elite in Rome were often the owners of these estates and they used their power to maintain their authority and to get the most important resource needed to produce their wealth: slaves. So essentially Roman elite used their money to buy power and then used power to ensure their wealth.

This question is greatly affected but the period at which you are looking. For ease of giving a basic understanding, I will limit my response to the period of 143BC- 43BC, this period is 10 years prior to Tiberius being elected tribune, through to the death of Cicero. I will be focusing on two main groups the equities, and the senatorial class.

The Senatorial class derived the majority of their wealth through successful use of massive farming efforts, conducted by a largely slave labor force, these were known as Latifundia. Production on these latifundia was varied everything from wine to corn, to sheep, were produced . They also produced a large portion of grain. The majority of these farms were located in the southern parts of Italy ; this is shown through population movements which in turn were a partial cause for the introduction of the Lex Sempronia Agraria. Inheritance was common place occurred and was common place. For the most part the Senatorial class refrained from taking an active part in commerce as after the passage of the Lex Claudia , they were forbidden from taking part in commerce. Thus they needed something to invest the vast wealth their families had acquired, and the answer to this question was land.

The Equities, or Knights were essentially the business class or Rome, as a result of the previously mentioned Lex Claudia they dominated Rome’s commercial dealings. They traded widely and accumulated enough wealth to; in many cases exceed that held by many of the senators . One of the most lucrative means through which this class could increase their wealth was to act as state tax collectors. This was essentially the process of paying to taxes owed by a region and then going to that region to collect the taxes, for a profit . This is such an effective means of turning a profit that it is a major factor in the eventual trail of Verres by Cicero.

As a followup question, how did they receive the money? I can't imagine a late roman period rich man lifting a finger to get the money. Did they employ resellers? Did they sell directly to the government/warehouses or workshops?
