Due to its geographical location and vital dependence on the Nile River, Egypt considers its presence and influence in the Horn of Africa to be part of its national security and geopolitical strategy. This region, which includes the countries of Ethiopia, Somalia, Djibouti, Eritrea and Sudan, due to its proximity to the Red Sea and the Bab al-Mandab Strait, has become a focal point in strategic competitions between regional and international powers. This research, using the descriptive-analytical method and using the conceptual framework of strategic culture, seeks to answer this question: How has Egypt's attitude as a regional power in the Arab world and Africa influenced the country's policies in the Horn of Africa? This research argues that Egypt's strategic culture, which emphasizes the country's role as a central power in the Arab world and Africa, has led this country to more aggressive policies and increased presence in the Horn of Africa in order to consolidate its leadership role and influence the powers Limit the competitor.
