The All Saints' Flood was a significant meteorological event characterized by a severe storm that struck the Dutch coast, particularly impacting the region of Zeeland. Initiating on the evening of November 1 and continuing into November 2, 1570, the storm produced a particularly high tide that overwhelmed the dikes protecting the low-lying coastal areas. As the North Sea surged past these defenses, multiple towns were submerged, with the water levels rising rapidly, creating chaos among the population celebrating All Saints' Day.

Walcheren, Tholen, and the surrounding areas were some of the hardest-hit locations, where the storm's ferocity combined with unusually high spring tides led to extensive flooding. In many communities, homes were lost, farmlands rendered useless, and entire villages were swept away. According to historical accounts, casualties were substantial, with estimates of hundreds to thousands of lives lost, though precise numbers are difficult to ascertain due to the scattered nature of the event's impact. Survivors reported scenes of desperation, with many residents clinging to rooftops in a plea for rescue.

The recovery from this flood would take many years, as the local economy was deeply affected by the destruction of crops and livestock. The devastation also prompted discussions about the challenges of water management in the Netherlands, which was already facing constant battles against encroaching sea waters. This event would lead to significant advancements in flood management and ultimately influence Dutch policy on dike construction and land reclamation in subsequent years.
