To approximately in the year 1000 Eersel belonged to the county of Taxandria. Hereafter it came under the influence of earl of Guelders. The Earl of Leuven extends its area to the north and in 1203 the region definitively became a part of Brabant. Trading started to develop and Eersel became a cross point for the routes of Leuven and 's-Hertogenbosch and of Antwerp and Turnhout. The triangular court of the village 'Hint' (now still visible), was extended in southern direction. The new oval square became ‘de Markt’ (the Market) constructed for the trade as a parking place for carts. Around arose the characteristic buildings for digest and boardinghouses such as taverns. But also stables for horses with the requirements like a blacksmith. In 1325 Eersel obtained the rights of ‘freedom’ (Town privileges) from Duke Jan III of Brabant. On this basis the inhabitants could designate as of now their own governor. Eersel became the head of regional schepenbank of Hapert, Hoogeloon, Vessem, Knegsel, Steensel, Bergeijk, Westerhoven, Dommelen en Borkel en Schaft. Around the 14th century Eersel became prosperous and the monumental tower of Eersel was built, together with those of Steensel and Duizel. In 1464 between the market and ‘het Hint’ a chapel was built in Eersel. After the Middle Ages the region became more poorly and the villages did not grow between 1500 and 1800. This is the period of the ‘Teuten’ a traveling trading people, who were touring from village to village with artisan and merchant services, like coppersmith, wig-maker, also some veterinary surgeon like horse, ram, bull and pig castrating, and trade in goods like pottery, kitchen-utensil, bed-clothes, linen, lace, silk and other textile manufactures. They were no gypsies but build their homes in a central place like Eersel and traveled to other regions and lands from there. One of the remainder of this time are the houses of the ‘Teuten’ at the market. In 1800 at the time of King Willem I there came some improvement. The provincial road to Eindhoven and the road to Postel was hardened and a steam tram railway was manufactured. (1897)  In 1923 Eersel absorbed the former municipality of Duizel en Steensel.
