is noteworthy in 19th century Germanic interpretations as to why the "march of the Roman Empire" was halted, but in reality Roman punitive campaigns into Germania continued and they were intended less for conquest or expansion than they were to force the Germanic alliance into some kind of political structure that would be compliant with Roman diplomatic efforts. The most famous of those incursions, led by the Roman emperor Maximinus Thrax, resulted in a Roman victory in 235 AD at the Battle at the Harzhorn Hill, which is located in the modern German state of Lower Saxony, east of the Weser river, between the towns of Kalefeld and Bad Gandersheim. After the Marcomannic Wars, the Romans even managed to occupy the provinces of Marcomannia and Sarmatia, corresponding to modern Czech Republic, Slovakia and Bavaria/Austria/Hungary north of Danube. Final plans to annex those territories were discarded by Commodus deeming the occupation of the region too expensive for the imperial treasury. After Arminius was defeated and dead, having been murdered in 21 AD by opponents within his own tribe, Rome tried to control Germania beyond the Limes indirectly, by appointing client kings. Italicus, a nephew of Arminius, was appointed king of the Cherusci, Vangio and Sido became vassal princes of the powerful Suebi, and the Quadian client king Vannius was imposed as a ruler of the Marcomanni. Between 91 and 92 during the reign of emperor Domitian, the Romans sent a military detachment to assist their client Lugii against the Suebi in what is now Poland. Roman controlled territory was limited to the modern states of Austria, Baden-Württemberg, southern Bavaria, southern Hesse, Saarland and the Rhineland as Roman provinces of Noricum, Raetia and Germania. The Roman provinces in western Germany, Germania Inferior (with the capital situated at Colonia Claudia Ara Agrippinensium, modern Cologne) and Germania Superior (with its capital at Mogontiacum, modern Mainz), were formally established in 85 AD, after a long period of military occupation beginning in the reign of the emperor Augustus. Nonetheless, the Severan-era historian Cassius Dio is emphatic that Varus had been conducting the latter stages of full colonization of a greater German province, which has been partially confirmed by recent archaeological discoveries such as the Varian-era Roman provincial settlement at Waldgirmes Forum.
