The town began to grow rapidly after the victory of Rudolf I of the Habsburg dynasty over King Otakar II of Bohemia in 1278. The town built fortifications, and trade, viticulture, and crafts started to grow. The town had a monopoly over the entire region and also controlled the viticulture trade with Carinthia. The first churches were built, and also around this time the first Jews arrived. The Jews built their own ghetto in the southeastern part of town, where they also built the Maribor Synagogue. Most Slovenians lived in the northwestern part of town on what is now Slovenian Street ("Slovenska ulica").
