The Aksumite state emerged at about the beginning of the Christian era, flourished during the succeeding six or seven centuries, and underwent prolonged decline from the eighth to the twelfth century A.D. Aksum's period of greatest power lasted from the fourth through the sixth century. Its core area lay in the highlands of what is today southern Eritrea, Tigray, Lasta (in present-day Welo), and Angot (also in Welo) its major centers were at Aksum and Adulis. Earlier centers, such as Yeha, also continued to flourish. At the kingdom's height, its rulers held sway over the Red Sea coast from Sawakin in present-day Sudan in the north to Berbera in present-day Somalia in the south, and inland as far as the Nile Valley in modern Sudan. On the Arabian side of the Red Sea, the Aksumite rulers at times controlled the coast and much of the interior of modern Yemen. During the sixth and seventh centuries, the Aksumite state lost its possessions in southwest Arabia and much of its Red Sea coastline and gradually shrank to its core area, with the political center of the state shifting farther and farther southward.

Inscriptions from Aksum and elsewhere date from as early as the end of the second century A.D. and reveal an Aksumite state that already had expanded at the expense of neighboring peoples. The Greek inscriptions of King Zoskales (who ruled at the end of the second century A.D.) claim that he conquered the lands to the south and southwest of what is now Tigray and controlled the Red Sea coast from Sawakin south to the present-day Djibouti and Berbera areas. The Aksumite state controlled parts of Southwest Arabia as well during this time, and subsequent Aksumite rulers continually involved themselves in the political and military affairs of Southwest Arabia, especially in what is now Yemen. Much of the impetus for foreign conquest lay in the desire to control the maritime trade between the Roman Empire and India and adjoining lands. Indeed, King Zoskales is mentioned by name in the Periplus of the Erythrean Sea (the Latin term for the Red Sea is Mare Erythreum), a Greek shipping guide of the first to third centuries A.D., as promoting commerce with Rome, Arabia, and India. Among the African commodities that the Aksumites exported were gold, rhinoceros horn, ivory, incense, and obsidian in return, they imported cloth, glass, iron, olive oil, and wine.

During the third and fourth centuries, the traditions related to Aksumite rule became fixed. Gedara, who lived in the late second and early third centuries, is referred to as the king of Aksum in inscriptions written in Gi'iz (also seen as Ge'ez), the Semitic language of the Aksumite kingdom. The growth of imperial traditions was concurrent with the expansion of foreign holdings, especially in Southwest Arabia in the late second century A.D. and later in areas west of the Ethiopian highlands, including the kingdom of Meroë .

Meroë was centered on the Nile north of the confluence of the White Nile and Blue Nile. Established by the sixth century B.C. or earlier, the kingdom's inhabitants were black Africans who were h 1000 heavily influenced by Egyptian culture. It was probably the people of Meroë who were the first to be called Aithiopiai ("burnt faces") by the ancient Greeks, thus giving rise to the term Ethiopia that considerably later was used to designate the northern highlands of the Horn of Africa and its inhabitants. No evidence suggests that Meroë had any political influence over the areas included in modern Ethiopia economic influence is harder to gauge because ancient commercial networks in the area were probably extensive and involved much long-distance trade.

Sometime around A.D. 300, Aksumite armies conquered Meroë or forced its abandonment. By the early fourth century A.D., King Ezana (reigned 325-60) controlled a domain extending from Southwest Arabia across the Red Sea west to Meroë and south from Sawakin to the southern coast of the Gulf of Aden. As an indication of the type of political control he exercised, Ezana, like other Aksumite rulers, carried the title negusa nagast (king of kings), symbolic of his rule over numerous tribute-paying principalities and a title used by successive Ethiopian rulers into the mid-twentieth century.

The Aksumites created a civilization of considerable distinction. They devised an original architectural style and employed it in stone palaces and other public buildings. They also erected a series of carved stone stelae at Aksum as monuments to their deceased rulers. Some of these stelae are among the largest known from the ancient world. The Aksumites left behind a body of written records, that, although not voluminous, are nonetheless a legacy otherwise bequeathed only by Egypt and Meroë among ancient African kingdoms. These records were written in two languages--Gi'iz and Greek. Gi'iz is assumed to be ancestral to modern Amharic and Tigrinya, although possibly only indirectly. Greek was also widely used, especially for commercial transactions with the Hellenized world of the eastern Mediterranean. Even more remarkable and wholly unique for ancient Africa was the minting of coins over an approximately 300-year period. These coins, many with inlay of gold on bronze or silver, provide a chronology of the rulers of Aksum.

One of the most important contributions the Aksumite state made to Ethiopian tradition was the establishment of the Christian Church. The Aksumite state and its forebears had certainly been in contact with Judaism since the first millennium B.C. and with Christianity beginning in the first century A.D. These interactions probably were rather limited. However, during the second and third centuries, Christianity spread throughout the region. Around A.D. 330- 40, Ezana was converted to Christianity and made it the official state religion. The variant of Christianity adopted by the Aksumite state, however, eventually followed the Monophysite belief, which embraced the notion of one rather than two separate natures in the person of Christ as defined by the Council of Chalcedon in 451 (see Ethiopian Orthodox Christianity, ch. 2).

Little is known about fifth-century Aksum, but early in the next century Aksumite rulers reasserted their control over Southwest Arabia, though only for a short time. Later in the sixth century, however, Sassanian Persians established themselves in Yemen, effectively ending any pretense of Aksumite control. Thereafter, the Sassanians attacked Byzantine Egypt, further disrupting Aksumite trade networks in the Red Sea area. Over the next century and a half, Aksum was increasingly cut off from its overseas entrepô ts and as a result entered a period of prolonged decline, gradually relinquishing its maritime trading network and withdrawing into the interior of northern Ethiopia.
