witan
The Anglo-Saxon national council or witenagemot.
But in estimating the powers of the witan, we must not lose sight of the fact, that the king sometimes assumes a tone of superiority scarcely consistent with its independence.
Where it comes from
Learned borrowing from Old English witan, plural of wita (“wise man”).
