major defeat in 1242 in the Battle of the Ice at the hands of Prince Alexander Nevsky of Novgorod. Over the next decades the Order focused on the subjugation of the Curonians and Semigallians. In 1260 it suffered a disastrous defeat in the Battle of Durbe against Samogitians, which inspired rebellions throughout Prussia and Livonia. After the Teutonic Knights won a crucial victory in the Siege of Königsberg from 1262 to 1265, the war had reached a turning point. The Curonians were finally subjugated in 1267 and the Semigallians in 1290. The Order suppressed a major Estonian rebellion in 1343–1345, and in 1346 purchased the Duchy of Estonia from Denmark. Against Lithuania The Teutonic Knights began to direct their campaigns against pagan Lithuania (see Lithuanian mythology), due to the long existing conflicts in the region (including constant incursions into the Holy Roman Empire's territory by pagan raiding parties) and the lack of a proper area of operation for the Knights, after the fall of the Kingdom of Jerusalem at Acre in 1291 and their later expulsion from Hungary. At first the knights moved their headquarters to Venice, from which they planned the recovery of Outremer, this plan was, however, shortly abandoned, and the Order later moved its headquarters to Marienburg, so it could better focus its efforts on the region of Prussia. Because "Lithuania Propria" remained non-Christian until the end of the 14th century, much later than the rest of eastern Europe, the conflicts stretched out for a longer time, and many Knights from western European countries, such as England and France, journeyed to Prussia to participate in the seasonal campaigns (reyse) against the Grand Duchy of Lithuania. In 1348, the Order won a great victory over the Lithuanians in the Battle of Strėva, severely weakening them. The Teutonic Knights won a decisive victory over Lithuania in the Battle of Rudau in 1370. Warfare between the Order and the Lithuanians was especially brutal. It was common practice for Lithuanians to torture captured enemies and civilians, it is recorded by a Teutonic chronicler that they had the habit of tying captured Knights to their horses and having both of them burned alive, while sometimes a stake would be driven into their bodies or the Knight would be flayed. Lithuanian pagan customs included ritualistic human sacrifice, the hanging of widows, and the burying of a warrior's horses and servants with him after
