The municipality of Leiden had a population of 123,856 in August 2017, but the city forms one densely connected agglomeration with its suburbs Oegstgeest, Leiderdorp, Voorschoten and Zoeterwoude with 206,647 inhabitants. In 1572, the city sided with the Dutch revolt against Spanish rule and played an important role in the Eighty Years' War. Besieged from May until October 1574 by the Spanish, Leiden was relieved by the cutting of the dikes, thus enabling ships to carry provisions to the inhabitants of the flooded town. During the Dutch Golden Era, Leiden was the second largest city of Holland, after Amsterdam.[citation needed] Particularly due to the work by Herman Boerhaave (1668–1738), it played a crucial role in the establishment of modern chemistry and medicine. ./cache/en-wikipedia-org-8586.html ./txt/en-wikipedia-org-8586.txt
