After the Fall of Ifat, many ethnicities and kingdoms fell weak, among them the Oromo Muslims, so the Zay people expanded from their homeland
Enderta. When the Oromo first met the Zway people's they did not know what they were doing due to their smart modern fishing and sailing techniques. The Oromo gave them the name Laqi which means Paddler. The Oromo, and the Zway became friends and later protected each other. The Oromo and Zway lived in the area until the Maya expansion, where many Oromo and Zway were displaced. Brakumper states the Zay were a branch of the Harla. One noted ruler of the Zay dynasty of Wej is Ras Amdu a powerful king who annexed many Muslim provinces, the Abyssinians were so scared of him as well as the Muslims. One chronicle records this statement from the Court of Abyssinia.
“let us also have the Protection of the Muslims so that we can achieve our aims, and bring them in so that our religion may not be changed. But there is Ras Amdu as long as he lived the Moslims are weak and scared.” In order to weaken him in the eyes of the people the Abyssinian court spread rumour that he slept with Queen Eleni of Abyssinia when the people of Abyssinia heard this Amdu was furious, and he campaigned against the Maya, and Fetegar he in his campaign he invaded the two provinces. According to Tadesse Tamrat he ruled the whole of the Maya, Genz, Fatagar, Wej, and
Lake Hayq. King
Eskender supported the Muslims the Negus captured and killed Amdu. When the news spread that the second most powerful monarch of Ethiopia died, Welde Silus, Amdu’s nephew, swore to kill Eskender. After Amdu’s death Welde ascended the throne, under his rule the Maya and Zway we’re subjugated, Welde led his forces to
Enderta, Eskender responded by attacking them. Welde’s forcers consisted of Maya archers, which used arrows dipped in poison. He himself killed Eskender. The chronicle states that he swore not to spare the king, this would lead to Fetegar and Wej expanding, Wej and Fetegar invaded the Genz and
Ifat province's and took their cattle. Fetegar and Wej became one of the most powerful kingdoms in the Horn of Africa. They would also convert all the inhabitants of Genz and Shewa to islam. Welde moved his capital to Zway then known as Jarecho. == Ethiopian-Adal War ==
