He became a chamberlain of King
Sigismund in 1590. Four years later, he left Sigismund and started to support Sigismund's cousin
Duke Carl, who was an enemy of Sigismund and challenged the king for the throne. Brahe received various important assignments from Duke Carl, and eventually, in 1602, Brahe became
Lord High Constable (Swedish:
riksmarsk) and a member of the
Swedish Privy Council. Brahe's older brothers had supported Sigismund which led to them losing the Visingsborg earldom. Having been a trustful supporter of Duke Carl, who became regent of Sweden in 1599 and king 1604, Brahe was declared Count of Visingsborg instead. When King Carl IX died and was succeeded by his son
Gustavus Adolphus in 1611, Brahe remained a close confidant of the new king. The same year, he was appointed
Lord High Steward (Swedish:
riksdrots), becoming arguably the most prominent member of the Privy Council. In 1614, he was made the first president of
Svea Court of Appeal, when this court was created. Brahe was knighted at the coronation of Gustavus Adolphus in October 1617. ==Family life and death==
