Caligula Accepts Roman Principate Titles
Following the death of Emperor Tiberius on March 16, 37 CE, the Roman Senate moved swiftly to consolidate power in the hands of his designated successor, Gaius Julius Caesar Germanicus, known as Caligula. The young heir, then about 25 years old, had been in Misenum when news of Tiberius's passing reached him. Praetorian Guard support helped secure his position, after which the Senate convened to grant him the full authority of the Principate in a single legislative act. On March 28, Caligula entered Rome and received the comprehensive powers previously accumulated piecemeal by Augustus and Tiberius. This rapid transfer marked a shift toward more centralized imperial rule. The event stabilized the transition but set precedents for future successions.
Why it matters: The conferral of powers on March 28 established a model for instantaneous imperial authority that later emperors would follow, reducing the Senate's influence over time. It reinforced the Julio-Claudian dynasty's dominance and highlighted the Praetorian Guard's growing role in Roman politics. This consolidation influenced the evolution of the Roman Empire's governance structure for centuries.
Britain and France Declare War on Russia
Tensions over influence in the Ottoman Empire and the Eastern Question escalated after Russia's victory at the Battle of Sinop in late 1853. Britain and France, seeking to curb Russian expansion and protect their strategic interests in the Black Sea region, issued an ultimatum that Russia ignored. On March 28, 1854, Britain formally declared war, with France following suit shortly thereafter. This alliance with the Ottoman Empire and later Sardinia transformed a regional conflict into a broader European war. The declarations committed major powers to a prolonged campaign focused on the Crimean Peninsula. Naval and land operations soon followed.
Why it matters: The March 28 declarations launched the Crimean War, which exposed weaknesses in Russian military organization and led to significant reforms under Tsar Alexander II. It also shaped modern international alliances and diplomacy, contributing to the decline of the Concert of Europe system. The conflict's outcome influenced later European power balances and the Eastern Question.
Battle of Glorieta Pass Ends Confederate Hopes in West
During the American Civil War, Confederate forces under Brigadier General Henry Hopkins Sibley advanced into New Mexico Territory to secure western resources and supply lines. Union troops, including Colorado and New Mexico volunteers led by Colonel John P. Slough, intercepted them near Glorieta Pass on the Santa Fe Trail. Skirmishes began on March 26, with the decisive engagement occurring on March 28. Union forces destroyed the Confederate supply train in a flanking maneuver while the main battle raged. The Confederates, though tactically successful in the pass itself, lost their logistical base and were forced to retreat. This outcome halted their campaign in the region.
Why it matters: The March 28 fighting at Glorieta Pass secured Union control of the Southwest, preventing Confederate access to California gold and Pacific ports. It preserved federal authority in the territories and demonstrated the importance of logistics in western warfare. The battle remains a key example of how peripheral campaigns affected the broader Civil War strategy.
Nationalists Capture Madrid, Ending Spanish Civil War
After nearly three years of fighting between Republican loyalists and Nationalist rebels led by General Francisco Franco, the Republican position in central Spain collapsed. Internal Republican divisions and a final offensive by Nationalist forces in late March left Madrid isolated. On March 28, 1939, Nationalist troops entered the capital without significant resistance as Republican defenders surrendered. This occupation effectively concluded major combat operations across Spain. Franco's forces quickly consolidated control over remaining territories. The victory established the Francoist regime that would govern Spain until 1975.
Why it matters: The fall of Madrid on March 28 symbolized the triumph of authoritarian forces in Spain and presaged alliances with Nazi Germany and Fascist Italy during World War II. It triggered mass exiles and repression, shaping Spanish society and politics for decades. The war's outcome influenced Cold War alignments and European perceptions of fascism versus democracy.
Three Mile Island Nuclear Accident Begins
At the Three Mile Island Nuclear Generating Station in Pennsylvania, a series of equipment failures and operator errors unfolded in the early morning hours. A stuck relief valve allowed coolant to escape from the Unit 2 reactor, leading to overheating and partial core meltdown. Plant operators initially misread instruments and took actions that worsened the situation. By midday on March 28, 1979, radioactive gases had been released, prompting public concern and evacuations. The incident was contained without immediate fatalities, but it exposed critical flaws in reactor design, training, and emergency procedures. Investigations followed rapidly.
Why it matters: The March 28 accident prompted sweeping regulatory reforms by the U.S. Nuclear Regulatory Commission, including improved operator training, better instrumentation, and enhanced emergency planning. It slowed nuclear power expansion in the United States and increased public scrutiny of the industry worldwide. The event remains a benchmark for nuclear safety standards and risk communication.
