In 1625, Dutch jurist Hugo Grotius published 'De jure belli ac pacis', a foundational text in international law. Grotius argued that natural rights exist independently of divine command or political authority, establishing principles that would influence legal thought for centuries. His work laid the groundwork for modern concepts of justice and human rights, shaping the discourse on war, peace, and international relations.

Hugo Grotius's 1625 publication of 'De jure belli ac pacis' introduced concepts of universal human rights and just war theory. His ideas provided an ethical framework that influenced Enlightenment political poetry, inspiring poets like Voltaire and later anti-imperialist writers who critiqued the moral implications of war.
