Eritrea is a strategically located country in the Horn of Africa, commanding a long coastline along the Red Sea. Its geography acts as a bridge between the African interior and the maritime trade routes of the Middle East and Europe. It is slightly larger than the US state of Pennsylvania. The nation's territory includes the Dahlak Archipelago, a group of over 200 islands known for their coral reefs and historical pearl fisheries. Eritrea’s modern identity is forged from its 30-year war for independence, which concluded in 1991, leading to its formal recognition as a sovereign state in 1993.

The country is administratively divided into six regions, known as zobas: Maekel (Central), Anseba, Gash-Barka, Debub (Southern), Semienawi Keyih Bahri (Northern Red Sea), and Debubawi Keyih Bahri (Southern Red Sea). This structure decentralizes administration across Eritrea's diverse terrains, from the high central plateau to the arid western lowlands and the volcanic southern panhandle. Asmara, the capital, is located in the Maekel region at an elevation of 2,325 meters. Its unique modernist architecture, built during the Italian colonial period, earned it a designation as a UNESCO World Heritage site.

Eritrea’s climate is sharply divided by its topography. The central highlands enjoy a temperate climate with two rainy seasons: the belg (short rains) from March to May and the kremti (main rains) from June to September. In contrast, the coastal plains and the Danakil Depression are among the hottest and driest places on Earth, with temperatures frequently exceeding 40°C. The western lowlands are semi-arid and primarily support pastoralism. These climate extremes make the country highly vulnerable to periodic droughts, which significantly impact food security and agricultural yields.
