Please give me a short bulleted list of key points about Ethiopia?

Context: Ethiopia is one of the oldest countries in Africa, the emergence of Ethiopian civilization dates back thousands of years. Due to migration and imperial expansion, it grew to include many other primarily Afro-Asiatic-speaking communities, including Amhara, Oromos, Somalis, Tigray, Afars, Sidama, Gurage, Agaw and Harari, among others. One of the first kingdoms to rise to power in the territory was the kingdom of D'mt in the 10th century BC, which established its capital at Yeha. In the first century AD the Aksumite Kingdom rose to power in the Tigray Region with its capital at Aksum and grew into a major power on the Red Sea, subjugating Yemen and Meroe. In the early fourth century, during the reign of Ezana, Christianity was declared the state religion. Ezana's reign is also when the Aksumites first identified themselves as "Ethiopians", and not long after, Philostorgius became the first foreign author to call the Aksumites Ethiopians. The Aksumite empire fell into decline with the rise of Islam in the Arabian peninsula, which slowly shifted trade away from the Christian Aksum. It eventually became isolated, its economy slumped and Aksum's commercial domination of the region ended. The Aksumites gave way to the Zagwe dynasty, who established a new capital at Lalibela before giving way to the Solomonic dynasty in the 13th century. During the early Solomonic period, Ethiopia went through military reforms and imperial expansion that allowed it to dominate the Horn of Africa. Portuguese missionaries arrived at this time
