He was Justiciar of Närke and a Lord High Councillor of Sweden from 1487.
[1] Erik Arvidsson was born around 1460 into an important family of high nobility and was apparently aiming at a clerical career.
Erik's parents were lord Arvid Birgersson Trolle (died 1505) and his first wife Kerstin Jonsdotter (Gädda).
Erik was elected Regent (riksföreståndare) at the meeting of the High Council of Sweden in 1512 upon the death of regent Svante Nilsson, Lord of Ekesiö, but never actually took office, being superseded by Svante's son, the young Sten Sture the Younger.
He married in 1487 the wealthy Ingeborg Philipsdatter (Thott) (died 1495), his stepmother's first cousin, as his first wife and settled on her manor Ekholmen Castle in Uppland.
