Juan Bautista Alberdi was born in 1810 in Tucuman, Argentina, and emerged as a leading political theorist and diplomat. His seminal work, Bases y puntos de partida para la organización política de la República Argentina, provided the ideological foundation for Argentina's 1853 Constitution. Exiled during the rule of Juan Manuel de Rosas, he wrote extensively on liberalism, immigration, and economic development. Alberdi served as a diplomat in the United States and Europe, promoting Argentina's interests abroad. He died in France in 1884 and is remembered as one of the founding fathers of the Argentine nation.

Syed Zafarul Hasan was born in 1885 in British India and became a leading thinker in the study of Islamic philosophy.

Hasan's intellectual legacy continues to inspire scholars in the fields of philosophy and religious studies. He passed away on June 19, 1949, leaving behind a rich body of scholarly work that remains influential.

Ali Shariati (1933–1977) was an Iranian sociologist and philosopher who blended social theory with Islamic thought. He studied at the University of Paris and emerged as a leading voice against both Western imperialism and rigid clericalism. His dynamic lectures and writings, including the influential essay "Haji Firuz in the Guise of Jonathan Swift," reached thousands of students and activists. Shariati framed history and religion as tools for social revolution, earning him the title 'ideologue of the Iranian Revolution.' His untimely death in 1977 remains controversial, fueling numerous conspiracy theories. His legacy continues to influence sociopolitical discourse in Iran and beyond.
