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"). In the beginning of the 13th century Esztergom was the center of the country's political and economic life. This is explained by the canon of Nagyvárad, Rogerius of Apulia, who witnessed the first devastation of the country during the Tatar invasion siege of Esztergom and wrote in his Carmen Miserabile ("Sad Song"): "since there was no other town like Esztergom in Hungary, the Tatars (siege of Esztergom) were considering crossing the Danube to pitch a camp there", which was exactly what happened after the Danube froze. The capital of the Árpád-age was destroyed in a vicious battle. Though, according to the documents that remained intact, some of the residents (those who escaped into the castle) survived and new residents settled in the area and soon started rebuilding the town, it lost its leading role. Béla IV gave the palace and castle to the archbishop, and changed his residence to Buda. Béla IV and his family, however, were buried in the Franciscan church in Esztergom which had been destroyed during the invasion and which had been rebuilt by Béla IV in 1270. Following these events, the castle was built and decorated by the bishops. The center of the king's town, which was surrounded by walls, was still under royal authority. A number of different monasteries did return or settle in the religious center. Meanwhile, the citizenry had been fighting to maintain and reclaim the rights of towns against the expansion of the church within the royal town. In the chaotic years after the fall of the House of Árpád, Esztergom suffered another calamity: in 1304, the forces of Wenceslaus II, the Czech king occupied and raided the castle. In the years to come, the castle was owned by several individuals: Róbert Károly and then Louis the Great patronized the town. In 1327 Kovácsi, the most influential suburb of the town, lying in the southeast, was united with Esztergom. The former suburb had three churches with mainly blacksmith, goldsmith, and coiner residents. In the 14th and 15th centuries Esztergom saw events of great importance and became one of the most influential acropolises of Hungarian culture along with
