The surname Hasler was first found in Mecklenburg, where the name contributed greatly to the development of an emerging nation, and would later play a large role in the tribal and national conflicts of the area. Over time, the family name branched into other houses, where their influence continued to be felt because of the important role they played in the local social and political affairs.
