The First Dynasty of Ur had enormous wealth as shown by the lavishness of its tombs. This was probably due to the fact that Ur acted as the main harbour for trade with India, which put her in a strategic position to import and trade vast quantities of gold, carnelian or lapis lazuli. In comparison, the burials of the kings of Kish were much less lavish. High-prowed Summerian ships may have traveled as far as Meluhha, thought to be the Indus region, for trade.
