The following is the family tree of the Malay monarchs of Kelantan. While foreign sources include oblique references to the successive rulers who governed the city states of ancient Kelantan, a clear genealogy only emerges with Mansur Shah who reigned from 1465 to 1526. His father, Iskandar Shah is said to have been descendant of the ruler of the similarly obscure Kota Gelanggi.[1]
