Early life and family Joachim was born around 1424. He was the second son of duke
Casimir V from the
House of Griffin, who ruled the
Duchy of Pomerania-Stettin, and his wife,
Catherine of Brunswick-Lüneburg, a daughter of
Bernard I, duke of
Brunswick-Lüneburg. His parents probably had a first son named Joachim and gave their second son, born after his premature death, the same name. Due to that, he is nicknamed Joachim the Younger, while his older brother, Joachim the Elder. He also had two sisters, Anna, who was a wife of
John V of Mecklenburg, and Margaretha, was a wife of graf Albrecht III of Lindow-Ruppin. As a young child, Joachim was engaged to
Barbara of Brandenburg, a daughter of Margrave
John of Brandenburg, in 1427. The marriage did not materialize as Barbara married Margrave
Ludovico III Gonzaga in 1433 instead. Joachim married Barbara's younger sister
Elisabeth of Brandenburg in 1437. They had a son
Otto III, who was born in 1444. In 1442, Joachim granted the privileges to the town of
Neuwarp. The war ended on 3 May 1448, following the fighting in Pasewalk. The conflict ended with
status quo, with conquered towns remaining under Brandenburg control. == Citations ==
