On July 24, 1487 the good citizens of Leeuwarden impatience with restrictive beer laws sparked the Leeuwarden Beer Riots.

The Leeuwarden town leaders passed taxes on imported beer, and banned the sale of foreign beers in Leeuwarden. This did not sit well with thirsty people of the town and its surrounding farms. Beer was a staple drink in the medieval period. On that mid summer July summer day, a riot broke out when people demanded tavern keepers serve up beer from neighbouring region Haarlem, something forbidden by the new council edict. 

Matters came to a head on July 24, a market day, when a large number of farmers were in the city to sell their produce who desired to quench their thirst before heading home, prevailed upon a local tavernkeeper to open his stock of Haarlem Beer. When the incident was reported to the authorities, an attempt was made to arrest the tavernkeeper and expel his patrons, who were now well fortified with the strong brew. A general riot ensued, and in the following days, citizens from neighbouring towns, estimated to number more than 8,000, besieged the city hall demanding that the ban on imported beer end.

The following day, government troops were sent to put down the riots. It took three waves of attack before the rioters spirit broke and they fled.  I highly recommend History of Sorts write up of the event.  Its a bookmark worth website that explores various bits of history.
