The Ottoman Empire's governors of Egypt from 1517 to 1805 were at various times known by different but synonymous titles, among them beylerbey, viceroy, governor, governor-general, or, more generally, wāli. Furthermore, the Ottoman sultans very often changed positions of their governors in rapid succession, leading to complex and long lists of incumbents (this being the main reason for a political crisis in 1623, where the local Ottoman soldiers successfully sued to keep Kara Mustafa Pasha as governor after his replacement by after only one year).
