Livonian Brothers of the Sword founded by Albert of Riga
The Livonian Brothers of the Sword (Latin: Fratres militiæ Christi Livoniae, German: Schwertbrüderorden) was a Catholic military order established in 1202 during the Livonian Crusade by Albert, the third bishop of Riga (or possibly by Theoderich von Treydend). Pope Innocent III sanctioned the establishment in 1204 for the second time. The membership of the crusading order comprised warrior monks, mostly from northern Germany, who fought Baltic and Finnic "pagans" in the area of modern-day Estonia, Latvia and Lithuania. Alternative names of the Order include Christ Knights, Swordbrothers, Sword Brethren, Order of the Brothers of the Sword, and The Militia of Christ of Livonia. The seal reads: +MAGISTRI ETFRM (et fratrum) MILICIE CRI (Christi) DE LIVONIA.
Following their defeat by the Samogitians and Semigallians in the Battle of Schaulen (Saule) in 1236, the surviving Brothers merged into the Teutonic Order as an autonomous branch and became known as the Livonian Order.
