Otto IV of Brandenburg-Stendal

Otto IV (c. 1238–1308), called Otto with the Arrow, was the foremost of the three sons of John I ruling Brandenburg-Stendal jointly from 1266. The 1269 Treaty of Arnswalde made Duke Mestwin of Pomerelia their vassal.

Feuding with Magdeburg, he was captured and caged at the Battle of Fohse and freed for four thousand pounds of silver; an arrow wound at Staßfurt in 1280 gave him his nickname. As elector he backed Adolf of Nassau in 1292.
