Land's Advocate of Holland

The Land's Advocate (Dutch: landsadvocaat) of Holland acted as the chairman of the States of Holland. The office started in the early 14th century and ended in 1619, when the title was renamed into Grand Pensionary. He was the speaker of the nobility of Holland and had the first say on a subject during a meeting of the Estates. A decision of the Estates was made by a summarizing of all the statements of the other delegates by the Land's Advocate. The Land's Advocate of Holland was the most powerful man of the United Provinces when there was no Stadtholder in Holland (because two-thirds of the tax income of the republic came from the county of Holland).

The most powerful land's advocates of Holland were the last two, Paulus Buys (1572–1584) and Johan van Oldebarnevelt (1586–1619).
