Final answer:
The village that turned into a major port city due to the storm in 1287 was Amsterdam.
Step-by-step explanation:
In 1287, a storm flooded the land separating the North Sea and the Zuiderzee, turning Amsterdam into a major port city. This happened when the Saint Lucia's flood inundated parts of the Netherlands, and as a result, the small fishing village of Amsterdam, situated alongside the Amstel river, gained increased access to the sea and consequently developed into a prominent port for trade. Over time, due to this strategic advantage and other socio-economic factors, Amsterdam became one of the most important ports and trade centers in the world.
