Martin Luther King Jr.’s “Letter From Birmingham Jail” was little-noticed in April 1963, when his colleagues in the civil-rights movement stitched it together from the fragments he’d drafted in his cell. Major civil-rights legislation was not then on President John F. Kennedy’s agenda. Yet the letter has gained recognition as the 20th century’s most influential essay on civil disobedience.

As someone who grew up in the heart of the Deep South, I continue to be inspired by Martin Luther King Jr.’s “Letter From Birmingham Jail.” It reminds us that “injustice anywhere is a threat to justice everywhere”—whether during the height of segregation or in our communities today.

It’s difficult to imagine Christianity without the letters of Saint Paul, which continue to inform and influence pastoral traditions throughout the world, nearly 2,000 years after they were written.

The first letter, reportedly from Queen Atossa around 500 b.c., established the genre and made letters the most normal, effective form of long-distance communication for millennia. It also created whole industries of makers of writing materials, secretaries, and postal workers still flourishing today.

The inaugural letter posted with the “Penny Black,” the world’s first cheap, adhesive, prepaid stamp, enabled average folks to correspond with unprecedented abandon. Named for its price and its sober depiction of a 15-year-old Queen Victoria, the Penny Black was issued by Great Britain in May 1840. Other nations soon followed suit, including the United States in 1847.

A message unlikely ever to be answered, the Golden Record accompanying the Voyager spacecraft, which launched in 1977, springs from the same human impulse that perhaps gave rise to Paleolithic cave paintings and handprints: to record our memories, our questions, and ourselves.

Abraham Lincoln wrote five public letters that, by bolstering Northern morale, helped the Union win the Civil War, thus outlawing slavery, preserving national unity, and vindicating the idea of “government of the people, by the people, and for the people.” Arguably the best one was addressed to Albert Hodges, dated April 4, 1864, in which he said: “I am naturally anti-slavery. If slavery is not wrong, nothing is wrong.”

The “Groans of the Britons” letter, sent circa 450 a.d. by ancient Britons appealing for Roman help in resisting invaders. When no help came, the Britons asked Germanic mercenaries to come to their assistance—leading to the Germanic takeover of Britain. This was effectively the start of the English language.
