1543 was a landmark year in the , distinguished by the publication of two foundational texts that challenged prevailing medieval paradigms through empirical observation and mathematical reasoning: Nicolaus Copernicus's , which posited a heliocentric with orbiting the Sun, and Andreas Vesalius's De humani corporis fabrica, an anatomical atlas derived from direct human dissections that corrected longstanding errors in Galenic doctrine. These publications, released in and respectively, marked a causal shift toward modern science by prioritizing verifiable over scriptural or ancient , with Copernicus's model providing a mathematically simpler explanation for celestial motions despite resistance from geocentrists, and Vesalius's work enabling precise anatomical knowledge through woodcut illustrations of dissected cadavers. The year also saw geopolitical developments, including the Portuguese-Ethiopian victory at the against forces, bolstering Christian alliances in the , and the Treaty of Greenwich between and aimed at unification but ultimately rejected. Notable births included on January 31, who would later establish the unifying after centuries of civil war, while deaths encompassed Copernicus himself on May 24 and explorer Juan Rodríguez Cabrillo on January 3 during his Pacific voyage. Overall, 1543 exemplified the interplay of intellectual breakthroughs and global expansions that propelled from toward empirical modernity.

His work, based on mathematical modeling and observations challenging Ptolemaic geocentric doctrine, marked a pivotal shift toward modern astronomy, though it faced initial resistance from prevailing Aristotelian and ecclesiastical views. In June 1543, Flemish anatomist (1514–1564) published De humani corporis fabrica libri septem in , a groundbreaking treatise featuring woodcut illustrations of human dissections that corrected errors in ancient texts by and emphasized empirical observation over textual authority. The seven-volume work detailed musculoskeletal, vascular, and nervous systems with unprecedented accuracy, derived from Vesalius' direct cadaver studies at the , establishing standards for anatomical illustration and dissection that influenced medical science for centuries. These publications, occurring amid the Renaissance's emphasis on direct inquiry, underscored 1543's significance in challenging inherited knowledge through evidence-based methods, with Vesalius' reliance on fresh cadavers contrasting Galen's animal-based extrapolations to humans.

July–September

On July 1, and signed the Treaty of Greenwich, which included provisions for peace between the two kingdoms and a proposed marriage alliance between the infant Mary Stuart, Queen of Scotland, and , son of King , aimed at eventual . On July 7, French forces under Francis I invaded as part of broader military campaigns in the during the Italian War of 1542–1546.

The Ottoman fleet under Barbarossa then wintered in the French port of Toulon, housing 30,000 sailors and displacing locals through the winter of 1543-1544, with King Francis I promising compensation to the Toulonnais.

On September 12, the Treaty of was signed between William of Jülich-Cleves-Berg and Charles V, ceding territories in the Lower Rhine region and neutralizing a potential French ally in the ongoing wars.

The work, dedicated to , included mathematical models and observations supporting the Copernican theory, though it retained some epicycles for accuracy. Andreas Vesalius released De humani corporis fabrica libri septem in through Joannes Oporinus, featuring illustrations of human dissections that corrected Galenic errors and established empirical . The text emphasized direct observation over ancient authority, with detailed depictions of muscles, organs, and skeletons by artists like Jan van Calcar. Martin Luther issued Von den Jüden und iren Lügen (On the Jews and Their Lies), a 65,000-word urging expulsion, property confiscation, and destruction to counter perceived Jewish threats to . Mikael Agricola printed Abckiria, the first book in Finnish, serving as a primer and to promote Lutheran literacy in .
