Hungary declares itself independent of Austria with Lajos Kossuth as its leader.
On April 14, 1849, Hungary declared independence from the Austrian Empire with Lajos Kossuth at its head. This act formalized the aspirations of the 1848 Revolution and challenged Habsburg authority.
Amid the broader Revolutions of 1848, Hungarian patriots sought to end Vienna's domination and establish a constitutional government. Lajos Kossuth, a fiery orator and politician, was appointed Regent-President and led the proclamation in Debrecen. The declaration granted Hungary full autonomy and inspired national unity across various social groups. Vienna responded by seeking Russian military assistance, leading to a joint Austrian-Russian campaign. By August 1849, Hungarian forces were defeated, and imperial rule was reasserted violently. Despite its military failure, the independence declaration became a cornerstone of modern Hungarian identity and laid groundwork for later compromise within the Austro-Hungarian Empire.

U.S. President Abraham Lincoln is shot in Ford's Theatre by John Wilkes Booth; Lincoln dies the following day.
On the night of April 14, 1865, President Abraham Lincoln was assassinated by John Wilkes Booth while attending a play at Ford's Theatre. His death the following morning shocked a nation emerging from the Civil War.
Abraham Lincoln attended a performance of Our American Cousin with his wife in the theatre's balcony. John Wilkes Booth, a Confederate sympathizer and famous actor, slipped into the box and fired a pistol at close range. Lincoln was mortally wounded and was carried across the street to the Petersen House, where he died at dawn on April 15. The assassination was part of a wider conspiracy targeting top government officials. Booth fled but was killed days later by Union soldiers. Lincoln's death intensified public mourning and complicated the process of Reconstruction under his successor, Andrew Johnson. The tragedy remains one of America's most profound episodes of national loss.

William H. Seward, the U.S. Secretary of State, and his family are attacked at home by Lewis Powell.
On the same night as Lincoln's assassination, Secretary of State William H. Seward survived a brutal attack at his home by Lewis Powell. This foiled assassination attempt was part of a broader Confederate plot to decapitate the U.S. government.
Just hours after Lincoln was shot, Lewis Powell forced his way into Seward's Washington residence under the pretense of delivering medicine. Powell stabbed Seward multiple times, crushing the jaw of his infant son who tried to intervene. A neck harness from a carriage deflected a fatal blow, allowing Seward to survive the life-threatening wounds. Members of Seward's household and his bodyguard rushed to his aid, subduing Powell until authorities arrived. The attack was orchestrated by Booth as one element of a plan to throw the Union government into chaos. Seward's recovery and the capture of conspirators brought a measure of closure to the nation. In later years, Seward reflected that his survival embodied the resilience of the young republic.

The 1931 constitution enshrined universal suffrage and civil liberties but also sowed seeds of division. The republic’s tumultuous early years foreshadowed the Spanish Civil War that erupted in 1936.
