The fall of Henry the Lion was not followed by any anti-German reaction; and meanwhile the work of conversion had been going forward among the Slavs beyond the Oder. The first attempts of the Poles to influence their troublesome Pomeranian neighbours failed. The ultimate success of a mission was due to a German. Otto, a native of Suabia, began as a schoolmaster in Poland. From chaplain to the Polish Prince the Emperor Henry V made him Bishop of Bamberg (1102); and, when Boleslas III had subdued part of Pomerania and found his bishops unwilling to attempt its conversion, he offered the task to Otto of Bamberg who, although an old man, undertook it with the consent of the Pope and the Emperor. He paid two visits--in 1124 and 1128--both to Western Pomerania, and established the bishopric of Wollin. The conversion was naturally imperfect, but the country never relapsed. The fierce islanders of Rgen could not then be touched, but ultimately gave way in 1168 before the combined secular and spiritual weapons of the Danish rulers. [Sidenote: Livonia.] From the middle of the twelfth century the cities of Bremen and Lübeck had established trading connections with Livonia. Following in the wake of the traders (1186) an Augustinian canon, Meinhard by name, preached Christianity under permission from a neighbouring Russian Prince, and he was made Bishop of Yrkill, on the Düna, under the Archbishop of Bremen. His successors, however, impatient at failure, organised a crusade from Germany. The third Bishop, Albert, took the recently founded trading centre Riga as his bishopric, and organised the knightly Order of the Brethren of the Sword (1202), to be under the control of the Bishop. He aimed at an united spiritual and temporal power in his own land, and in 1207 he accepted Livonia as a fief from King Philip of Suabia. But Albert's chief foes were those of his own household. The Knights of the Sword strove for independence and tried to establish themselves in Esthonia. Albert appointed his own nominee as Bishop there, who should act as a check upon the knights. Innocent III, however, gave the ecclesiastical supervision of Esthonia to the Danish Archbishop of Lund. But when the Danish King attempted to follow this up by asserting a political authority his forces were defeated by the Esthonians. German influences prevailed; Albert took Dorpat, made it the seat of a new bishopric, and organised the whole country ecclesiastically until his death in 1229; although it was not until 1255 that Riga became the Metropolitan of the Livonian and Prussian Churches. The Order of the Sword ceased to resist, and in 1237 it merged itself in the Teutonic Order in Prussia. The conversion of Livonia was followed by that of Semgallen in 1218, and finally the inhabitants of Courland, threatened on all sides, accepted baptism (1230) as the only alternative to slavery.
