Gustaf Banér

Gustaf Banér (May 19, 1547 – March 20, 1600) was a Swedish noble, member of the Privy Council of Sweden.

[1][2] Gustaf Axelsson Banér was born at Djursholm Castle, the son of the Privy Counselor Axel Nilsson and Margareta Pedersdotter (Bielke).

[3] He remained favoured by King John for a long time and was entrusted with several diplomatic missions, such as the royal election in Poland, in 1587, when King John's son Sigismund III was elected.

[4] He was stadtholder in Reval between 1588 and 1590, where there was a meeting in 1589 during which there was a rupture between Banér and the members of the privy council on the one side and King John III on the other.

When the duke's actions had led to a rupture with most of the members of the Privy council, Banér escaped to Denmark from where he tried to incite a Swedish rebellion.
