This Day in History on February 16: Union Captures Fort Donelson During Civil War

In the late 1500s, Europe’s religious and political tensions were already shaping daily life. On February 16, 1568, Spain’s king issued a decree establishing the Tribunal of the Inquisition in the Spanish Netherlands. The goal was to enforce Catholic orthodoxy in a region where Protestant ideas were spreading. Instead of restoring calm, harsh enforcement added fuel to resentment and helped push the Netherlands toward a long struggle for independence. The episode is remembered as an example of how state power, religion, and local identity can collide, with consequences that set the direction of entire regions for generations.

On February 16, 1862, during the American Civil War, the Union captured Fort Donelson in Tennessee. The victory opened key rivers for Union movement and marked a major step in controlling the Confederate interior. It also elevated Ulysses S. Grant as a leading commander. The battle’s impact went beyond one campaign, because control of waterways and transportation routes often decides how long wars last and how costly they become.

On February 16, 1918, Lithuania declared independence, seeking to establish a modern state after centuries of shifting control by larger empires. The declaration did not end Lithuania’s struggles—occupation and war would follow—but it became a lasting reference point for national identity and later independence efforts. It remains significant because it shows how smaller nations tried to define themselves during a period when old empires were breaking apart and new borders were being drawn.

The modern era brought a different kind of global moment. On February 16, 2005, the Kyoto Protocol entered into force, committing participating countries to targets aimed at reducing greenhouse-gas emissions. The agreement mattered because it was one of the first major international efforts to set binding climate-related goals. Its longer-term importance lies in how it shaped later negotiations, created new tools for measuring emissions, and demonstrated both the potential and the limits of international cooperation when countries have different economies and priorities.

Notable births on February 16 span politics, art, and popular culture. In 1834, Ernst Haeckel was born in Germany. He became a prominent biologist and illustrator who helped popularize evolutionary ideas in Europe. His scientific drawings influenced how people visualized life’s diversity, even as some of his claims and interpretations were later challenged. Haeckel’s legacy shows how scientific communication can shape public understanding, for better and for worse.

Several notable deaths on February 16 also left lasting marks. In 1899, Félix Faure, president of France, died in office. His presidency took place during the Dreyfus Affair, a major political and social crisis that tested French institutions and public trust. Faure’s death did not resolve those tensions, but it marked a turning point in a period when debates over justice, evidence, and national identity were intensely public.

Taken together, February 16 threads through discovery, conflict, state-building, and creativity.
