With the increase of maritime trade to the Gulf region, the silver "Austrian Riyal" appeared. Also known as the Queen Theresa Riyal and as the "French Riyal," it weighed 28g and bore an image of Queen Maria Theresa (Queen of Hungary and Archduchess of Austria), who died in 1780. Its proper name is a thaler, which is thought to be part of the origin of the word "dollar."
