Biography
Lieuwe van Aitzema was a man of contradictions, operating in the glittering, cutthroat world of Dutch Golden Age politics. Officially, he served as a diplomatic agent for various German cities, granting him a front-row seat to treaty negotiations and state secrets. Unofficially, he was a spy, selling information to the highest bidder, and a libertine who fully embraced the era's excesses. This unique—and morally flexible—position allowed him to gather an unparalleled archive of documents, letters, and scandalous anecdotes. From this trove, he authored his massive "History of the Peace and Other Affairs," a riveting chronicle of the Dutch Republic that mixed high politics with salacious detail, making him an indispensable, if notoriously unreliable, source for historians of the period.
