A more thorough explanation:

PRO PARTE VIRILI

Pro parte virili is a Latin term that means "for the share per man." In history, it was used to refer to the equal distribution of something among a group of people, with each person receiving a share that is proportional to their contribution or status.

One example of pro parte virili is the division of land among heirs in ancient Rome. When a person died, their property was divided equally among their children, with each child receiving a share that is proportional to their gender and age. The sons received a larger share than the daughters, and the older children received a larger share than the younger ones.

Another example is the distribution of resources in a community. In some societies, resources such as food, water, and firewood were distributed among the members based on their needs and contributions. Each person received a share that is proportional to their family size, age, and ability to work.

The examples illustrate the concept of pro parte virili, which means that each person receives a share that is proportional to their contribution or status. In the case of land distribution in ancient Rome, the sons received a larger share than the daughters because they were expected to carry on the family name and provide for their families. Similarly, in the distribution of resources in a community, each person received a share that is proportional to their needs and ability to work, ensuring that everyone had access to the resources they needed to survive.
