This study explores the pastoral traditions of the Hamar tribe, tracing their origins to a migration from the Ari tribe in pursuit of preserving their pastoral way of life, distinct from the Ari's predominantly agrarian practices. Central to Hamar culture is the pivotal role of domestic livestock in societal sustenance and equilibrium. The dowry, a key aspect of marriage negotiations, is determined by the number of cattle and goats, underscoring the enduring significance of livestock in facilitating economic transactions, despite the presence of currency. Each man cherishes his favorite bull, known as the "erravak," which is adorned with a second name corresponding to its color. The bond with the erravak persists throughout the man's life, with eulogies composed in its honor and recited at the owner's funeral. Livestock husbandry not only forms the bedrock of Hamar tradition but also serves as a potent catalyst for preserving their cultural heritage amidst the challenges of globalization. This research elucidates the intrinsic link between pastoralism and cultural continuity among the Hamar, highlighting the resilience and adaptability of their traditions in a rapidly changing world. By delving into the intricate dynamics of Hamar livelihood practices, this study offers insights into the mechanisms through which traditional societies negotiate their identities and navigate external pressures while upholding their heritage.
