Unreached people group
The Arsi are one of the main subgroups of the great Oromo nation, primarily inhabiting the fertile lands and highlands of southern and southeastern Ethiopia. Recognized for their rich oral tradition, strong attachment to the land, and profound communal identity, they preserve a culture characterized by social cohesion and respect for ancestry.
Their mother tongue is a variant of the vast Oromo linguistic family, essential for passing down proverbs, poetry, and family histories. While living amidst modern transformations in Ethiopia, the Arsi maintain the traditional structures that govern their villages and social life.
Historically, the Arsi were part of the major Oromo expansion that reshaped the Horn of Africa starting in the sixteenth century, establishing themselves across the plains and mountains of the Rift Valley. For centuries, they were organized under the traditional age-grade and community governance system known as Gadaa.
In the late nineteenth century, the Arsi region was incorporated into the Ethiopian Empire after a period of intense conflict. This forced integration accelerated the conversion of much of the population to Islam, which came to serve as a symbol of unity, resilience, and distinct identity.

The Arsi economy centers on agriculture and livestock herding. In the highlands, they cultivate grains such as teff, barley, and wheat, while cattle, goats, and sheep occupy a central role in both nutrition and the social standing of families. Milk and dairy products are essential elements of their daily diet.
The community structure is deeply relational, grounded in kinship ties and community councils that maintain social order and mediate local disputes. Hospitality is regarded as a matter of honor, and community gatherings bring neighbors together for feasts, traditional coffee, and extended discussions about community affairs.
The vast majority of the Arsi population adheres to Sunni Islam, which has become a central pillar of collective identity and family life. Daily prayers, fasting, and Islamic holidays shape the rhythm of the year and organize village routines.
Beneath formal Islamic practice, elements of ancient Oromo beliefs remain alive in collective memory, particularly reverence for ancestral blessings and a sense of divine dependence for harvests. There is also a historical and evangelical Christian minority present in certain towns and communities throughout the region.
Although the complete Bible is translated into their mother tongue and digital resources are available, a strong oral tradition and functional illiteracy in rural areas mean that printed texts reach relatively few readers. For this reason, audio formats, spoken biblical storytelling, and oral broadcasts remain indispensable for the message of the Gospel to be clearly understood.

For many Arsi, the Islamic faith became deeply intertwined with historical resistance and the preservation of cultural identity against external pressures. Consequently, a decision to follow Jesus is often interpreted by family and community as a betrayal of ancestors and a departure from the clan, resulting in social rejection and intense family tensions.
Although inhabiting productive agricultural regions, many Arsi farmers face challenges from erratic rainfall, shortages of clean drinking water, and limited access to quality healthcare. Investment in rural schools and vocational training is urgently needed for youth.
On a spiritual level, there is a need for trained local leaders capable of teaching the Scriptures with depth, as well as faith communities that reflect Arsi culture and music in a welcoming, contextualized way.
