Ennarea, also known as E(n)narya or In(n)arya (Gonga: Hinnario), was a kingdom in the Gibe region in what is now western Ethiopia. It became independent from the kingdom of Damot in the 14th century and would be the most powerful kingdom in the region until its decline in the 17th century. Being located on the southwestern periphery of the Ethiopian Empire, Ennarea was its tributary throughout much of its history, supplying the emperor with gold and slaves. The culmination of this relationship was the Christianization of the Ennarean elite in the late 1580s. From the late 16th century the kingdom came under increasing pressure by the Oromo, who finally reconquered Ennarea in around 1710.

Our knowledge of Ennarea primarily comes from oral traditions and a few foreign written sources, as it had no indigenous literacy tradition.

According to oral traditions the royal Ennarean clan, the Hinnare Bushasho, originated in northern Ethiopia before settling in the Gibe region. In the 9th century Aksumite king Digna-Jan is said to have led a campaign into Innarya, accompanied by "150 priests carrying 60 consecrated tablets (tabot)".

In the 13th century, Ennarea was recorded to be a province of the Motalami's of Damot, a kingdom south of the Blue Nile. An early 19th-century document regarding the early history of Damot and Ennarea attests a political union of these two kingdoms.

It appears that since the late 14th century (around the same time when Kaffa was founded in the south) Ennarea gained nominal independence from its northern neighbor, although it remained in close contact with it. While Damot was soon annexed by the Ethiopian Empire Ennarea developed to the most important kingdom of the non-Muslim south, replacing Damot as one of the biggest gold and slave mines and degrading Kaffa and Bosa to tributaries. By the reign of Yeshaq I (early 15th century) Ennarea is attested to have been a tributary of the empire, although it seems likely that it had been so already since the campaigns of emperor Amda Seyon 100 years earlier. In a song dedicated to Yeshaq it is stated that Ennarea had to pay a tribute to the empire in the form of gold, slaves and cattle.

Between 1578 and 1586, the Borana Oromo reconquered the Gibe region, eventually taking the territory from around Ennarea to the Blue Nile. During this period of war the Oromo formed a new federation, known as Sadacha. It was the Sadacha who would continue to wage war against Ennarea for the next 130 years. In 1588 the Oromo took over Ennarea. It was probably this invasion that triggered the Ennarean wish to convert to Christianity. In the same year, emperor Sarsa Dengel pushed south of the Nile, into Ennarea, to bring Christianity. Although Ennarea lost the land between the main Gibe river and Gibe Ennarea due to another Sadacha attack in 1594 it managed to expand north.

In the 17th century, the Ennarea dynasty declined, as the Oromo weakened its economy by cutting it off from the Ethiopian empire. Eventually, in the mid 17th century, the royal clan of Kaffa seized power in Ennarea. Thus, Kaffa, but also Sheka, became independent from Ennarea. In 1704, an expedition led by emperor Iyasu I reached the kingdom, where he was confronted with a civil war between two throne claimants. It seems that Iyasu's expedition succeeded in pushing back Kaffa south to the Gojeb river. Six years later, under the rule of Shisafotchi, Ennarea was finally overrun by the Sadacha.

After the fall of the kingdom, Shisafotchi led an exodus south of the Gojeb river, into Kaffa. By the early 19th century this Ennarean exile kingdom had been defeated and vassalized by Kaffa, although its kings remained in nominal office until the Agar Maqnat. Cultural assimilation, slavery, epidemics and political repression made the Ennarean people vanish into history. Meanwhile, the Oromo settled in what once constituted Ennarea, changed their mode of production from pastoralism to agriculture, and, by the early 19th century, founded five kingdoms: Limmu-Ennarea, Jimma, Gera, Gomma and Gumma.
