Bogomilismball was considered to be a heretic sect of Orthodoxyball. It was founded in the First Bulgarian Empireball. Bogomilismball believed that churches should be humbly built and that the church shouldn't implement taxes. Apart from that, they believed in the old spiritual teachings and rejected the ecclesiastical Christianityball hierarchy. That made Christianityball VERY mad. It was present in Kingdom of Bosniaball, Bulgariaball, Italyball and many more countryballs. Bogomilismball had MANY issues with the Pope, and those issues were mainly the crusades. Kingdom of Bosniaball was the subject of the crusades during the reign of ban Matthew Ninoslaus(Matej Ninoslav). Many kings had to "convert" to Orthodoxyball in order to avoid future problems.
