The town council was made up of the richest citizens of the town (residents of French, Spanish, Dutch, and Italian origin) who dealt with commerce. The coat of arms of Esztergom emerged from their seal in the 13th century. This was the town where foreign monarchs could meet Hungarian kings. For example, Emperor Conrad II met Géza II in this town (1147). Another important meeting took place when the German Emperor Frederick Barbarossa visited Béla III. The historians traveling with them all agree on the richness and significance of Esztergom. Arnold of Lübeck, the historian with Frederick Barbarossa, called Esztergom the capital of Hungarian people ("quae Ungarorum est metropolis").
