Before he was killed by Khal Drogo, and before Daenerys had even married into the Dothraki horde, Viserys was known in Essos as the "Beggar King." When Daenerys and Viserys first fled Westeros in exile, they had valuable possessions like a royal crown. But during their travels and attempts at staying hidden, Viserys and Daenerys were robbed and left friendless. It was then that Viserys acquired the nickname "Beggar King," and Razdal's comment to Daenerys indicates that leaders in Essos have not forgotten this.
