One of the nobility (first called the Landtmarskalk), or marshal of the Diet, in the Riksdag ordinance of 1526) was now regularly appointed by the king as the spokesman of the Riddarhus, or House of Nobles, while the primate generally acted as the talman or president of the three lower estates, the clergy, burgesses and peasants, though at a later day each of the three lower estates elected its own talman.

At the diet of 1755-1756 he was elected landtmarskalk, or marshal.
