however, no known information regarding the knights' possible activities in Finland has survived. (Sweden eventually took over Finland after the Second Swedish Crusade in 1249.) In the Battle of Saule in 1236 the Lithuanians and Semigallians decimated the Order. This disaster led the surviving Brothers to become incorporated into the Order of Teutonic Knights in the following year, and from that point on they became known as the Livonian Order. They continued, however, to function in all respects (rule, clothing and policy) as an autonomous branch of the Teutonic Order, headed by their own Master (himself "de jure" subject to the Teutonic Order's Grand Master).
