[Nicolai, p.

725.] Joachim's first Wife, from whom descend the following Kurfursts, was a daughter of that Duke George of Saxony, Luther's celebrated friend, "If it rained Duke-Georges nine days running." JOACHIM GETS CO-INFEFTMENT IN PREUSSEN.
This second Wife, she of the accident at Grimnitz, was Hedwig, King Sigismund of Poland's daughter; which connection, it is thought, helped Joachim well in getting what they call the MITBELEHNUNG of Preussen (for it was he that achieved this point) from King Sigismund.
MITBELEHNUNG (Co-infeftment) in Preussen;--whereby is solemnly acknowledged the right of Joachim and his Posterity to the reversion of Preussen, should the Culmbach Line of Duke Albert happen to fail.

It was a thing Joachim long strove for; till at length his Father-in-law did, some twenty years hence, concede it him.
