 He adopted the name "Mudzaffar Shah" and established the sultanate of Kedah, which continues to rule today.The source for the list of sultans given here is the official genealogy given for the Sultan of Kedah.There are however discrepancies with the "Kedah Annals" as it lists only 5 sultans from the first convert Mudzaffar Shah to Sulaiman Shah who was captured by Aceh in 1619, in contrast to the twelve listed here.
