She is one of the Olympian Gods

One of the twelve Olympian Gods is Hera. A race of immortal gods in their third or fourth generation is known as the Olympians. They sit atop Mount Olympus and were revered as the main deities of the Greek pantheon. Zeus led his siblings to triumph over the Titans, who were the governing deities at the time, ending a 10-year conflict that resulted in the Olympians' eventual ascension to the position as supreme gods.

Even though Mount Olympus is home to many immortals, only 12 of them are regarded as being very significant. Along with Zeus' primary offspring Athena, Apollo, Artemis, Ares, Hephaestus, Hermes, Dionysus, and Aphrodite, these also include the Titans Cronus and Rhea's children Zeus, Hera, Poseidon, Demeter, and Hestia. Hera, who was Zeus' sister-wife, was regarded as the Queen of Gods and held a prominent position among the 12 Olympian Gods.
