1867— Emperor of Mexico executed

Austrian Archduke Ferdinand Maximilian, installed as emperor of Mexico by French Emperor Napoleon III in 1864, is executed on the orders of Benito Juarez, the president of the Mexican Republic.

In 1861, the liberal Mexican Benito Juarez became president of a country in financial ruin, and he was forced to default on his debts to European governments. In response, France, Britain, and Spain sent naval forces to Veracruz to demand reimbursement. Britain and Spain negotiated with Mexico and withdrew, but France, ruled by Napoleon III, decided to use the opportunity to carve a dependent empire out of Mexican territory. Late in 1861, a well-armed French fleet stormed Veracruz, landing a large French force and driving President Juarez and his government into retreat.

Certain that French victory would come swiftly in Mexico, 6,000 French troops under General Charles Latrille de Lorencez set out to attack Puebla de Los Angeles, a small town in east-central Mexico. From his new headquarters in the north, Juarez rounded up a rag-tag force of loyal men and sent them to Puebla. Led by Texas-born General Ignacio Zaragoza, the 2,000 Mexicans fortified the town and prepared for the French assault. On May 5, 1862, Lorencez drew his army, well-provisioned and supported by heavy artillery, before the city of Puebla and began his assault from the north. The battle lasted from daybreak to early evening, and when the French finally retreated they had lost nearly 500 soldiers to the fewer than 100 Mexicans killed.

Although not a major strategic victory in the overall war against the French, Zaragoza's victory at Puebla represented a great moral victory for the Mexican government and symbolized the country's ability to defend its sovereignty against threat by a powerful foreign nation.

1953 — Rosenbergs executed

On this day in 1953, Julius and Ethel Rosenberg, who were convicted of conspiring to pass U.S. atomic secrets to the Soviets, are executed at Sing Sing Prison in Ossining, New York. Both refused to admit any wrongdoing and proclaimed their innocence right up to the time of their deaths, by the electric chair. The Rosenbergs were the first U.S. citizens to be convicted and executed for espionage during peacetime and their case remains controversial to this day.

Julius Rosenberg was an engineer for the U.S. Army Signal Corps who was born in New York on May 12, 1918. His wife, born Ethel Greenglass, also in New York, on September 28, 1915, worked as a secretary. The couple met as members of the Young Communist League, married in 1939 and had two sons. Julius Rosenberg was arrested on suspicion of espionage on June 17, 1950, and accused of heading a spy ring that passed top-secret information concerning the atomic bomb to the Soviet Union. Ethel was arrested two months later. The Rosenbergs were implicated by David Greenglass, Ethel's younger brother and a former army sergeant and machinist at Los Alamos, the secret atomic bomb lab in New Mexico. Greenglass, who himself had confessed to providing nuclear secrets to the Soviets through an intermediary, testified against his sister and brother-in-law in court. He later served 10 years in prison.

The Rosenbergs vigorously protested their innocence, but after a brief trial that began on March 6, 1951, and attracted much media attention, the couple was convicted. On April 5, 1951, a judge sentenced them to death and the pair was taken to Sing Sing to await execution.

During the next two years, the couple became the subject of both national and international debate. Some people believed that the Rosenbergs were the victims of a surge of hysterical anti-communist feeling in the United States, and protested that the death sentence handed down was cruel and unusual punishment. Many Americans, however, believed that the Rosenbergs had been dealt with justly. They agreed with President Dwight D. Eisenhower when he issued a statement declining to invoke executive clemency for the pair. He stated, "I can only say that, by immeasurably increasing the chances of atomic war, the Rosenbergs may have condemned to death tens of millions of innocent people all over the world. The execution of two human beings is a grave matter. But even graver is the thought of the millions of dead whose deaths may be directly attributable to what these spies have done."
