The Lord High Chancellor was the effective head of government in Sweden, from 1538 to 1799, with periods of vacancy. The office holder was a member, and typically the leader, of the Privy Council. From 1634, the Lord High Chancellor was one of five Great Officers of the Realm, who were the most prominent members of the Privy Council and each presided over a branch of government—the Lord High Chancellor headed the Privy Council, making him the leader of the executive. In 1792, more than a century after the office's abolition in 1680, it was revived, but was then finally abolished again seven years later in 1799.
