Werle (or Wenden) was a fiefdom, or Herrschaft in German, roughly equivalent to a barony, in the Holy Roman Empire that was founded in 1235. It was created in the partition of territories in Mecklenburg that followed the death of Henry Borwin II of Mecklenburg (died 1226).
The royal (fürstlich in German) House of Werle was a spur line of the House of Mecklenburg line of the Obotrites. The Fiefdom of Werle lay in the area around Güstrow in today's Mecklenburg-Western Pomerania, Germany, and stretched eastward to Müritz. It was named after the then-capital Werle, now a village in the municipality Kassow, Rostock district.
The fiefdom collapsed several times into separate dominions. In 1277 it was divided among the sons of the first lord, or Herr in German, into Werle-Güstrow and Werle-Parchim. In 1307, both were reunited by Nicholas II, but they were divided again in 1316 into Werle-Güstrow and Werle-Goldberg. In 1337, Werle-Waren split off from the Werle-Güstrow line. With the death of the William, the last lord on September 7, 1436, the fiefdom once again reverted to Mecklenburg. The title of Lord of Werle was thenceforth carried by all rulers of Mecklenburg. Werle is represented in one of the seven fields of the coat of arms of Mecklenburg.
