The archdukes having consented to treat with the United Provinces "as free provinces and states over which they had no pretensions," Oldenbarneveldt, who had with him the States of Holland and the majority of burgher regents throughout the county, was for peace, provided that liberty of trading was conceded.
This date is memorable, as it marks the permanent accession of the Habsburg dynasty to the Bohemian throne, though the Austrian archdukes Rudolph and Albert had previously been rulers of Bohemia for short periods.
Accordingly in 1606 The the archdukes made a compact agreeing to acknowledge family the archduke Matthias as head of the family.
The advent of the new sovereigns, of officially known as " the archdukes," though greeted ands the r" with enthusiasm in the Belgic provinces, was looked upon with suspicion by the Dutch, who were as firmly resolved as ever to uphold their independence.
The Dutch, however, being masters of the sea, kept the coast closely blockaded, and through sheer exhaustion the king of Spain and the archdukes were compelled to agree to a truce for twelve years (9th of April 1609) with the United Provinces " in the capacity of free states over which Albert and Isabel made no pretensions."
