Explanation:

The Treaty of Verdun divided the empire which was built by Charlemagne  into 3  portions. These 3 portions was ruled by Charlemagne's three living grandsons. It was considered as a significant because it not only stated the beginning of the empire's dissolution, it gave out the general boundaries of what could  individually become nation-states of Europe.
