Marriage throughout the Republic is a social union or legal contract between people called spouses that establishes rights and obligations between the spouses, between the spouses and their children, and between the spouses and their in-laws. The definition of marriage varies according to different cultures, but it is principally an institution in which interpersonal relationships, usually intimate and sexual, are acknowledged.

Whilst there are several forms of worship throughout the empire, the most practiced form of worship recognizes twelve deities also known as the Titans and twenty one lesser gods, who were a primeval race of powerful deities, descendants of Gaia and Uranus, that ruled during the legendary Golden Age. They were immortal huge beings of incredible strength and stamina .

In the first generation of twelve Titans, the males were Oceanus, Hyperion, Coeus, Cronus, Crius, and Iapetus and the females - the Titanesses - were Mnemosyne, Tethys, Theia, Phoebe, Rhea and Themis. The second generation of Titans consisted of Hyperion's children Eos, Helios, and Selene; Coeus's daughters Leto and Asteria; Iapetus's children Atlas, Prometheus, Epimetheus, and Menoetius; Oceanus' daughter Metis; and Crius's sons Astraeus, Pallas, and Perses.

Social class in the republic is hierarchical, but there are multiple and overlapping social hierarchies, and an individual's relative position in one might be higher or lower than in another. The status of freeborn individuals is established by:

• ancestry;

• census rank,  based on wealth and political privilege, with the senatorial and noble ranks elevated above the ordinary citizen;

• attainment of honors ; and

• citizenship, of which there are grades with varying rights and privileges

There are also classes of non-citizens with different legal rights. Under the republic law, slaves are considered property and have no rights as such. However, some laws regulate slavery and offer slaves protections not extended to other forms of property such as animals. Slaves who had been manumitted are freedmen, and for the most part enjoy the same legal rights and protections as free-born citizens.
