After the loss of power of the Bahr negus in the aftermath of Bahr negus Yeshaq's rebellions, the title of Tigray mekonnen gained power in relation to the Bahr negus and at times included ruling over parts of what is now Eritrea, especially in the 19th century.[22] By the unsettled Zemene Mesafint period ("Era of the Princes"), both titles had sunken to little more than empty titles, and the Lord who in his turn dominated the region, used (and received from Emperor) the title of either Ras or Dejazmach, beginning with Ras Mikael Sehul. Rulers of Tigray such as Ras Wolde Selassie alternated with others, chiefly those of Begemder or Yejju, as warlords to rule in fact the Ethiopian monarchy during the Zemene Mesafint.
