March 15 gathers stories of power changing hands across very different eras. In 44 BCE, Julius Caesar was killed by Roman senators led by Brutus and Cassius, a dramatic reminder that even a powerful ruler could face organized opposition. More than eighteen centuries later, Andrew Jackson was born in 1767. A lawyer, general, and statesman, he would become the seventh U.S. president, expand presidential power, and champion Jacksonian democracy. One date thus links the violent end of a ruler’s life with the birth of a future political force.
The day’s other milestones pair political upheaval with a practical invention. In 1892, Jesse W. Reno patented a working escalator, first conceived as an amusement ride at Coney Island and later adopted as a transit staple. In 1917, after the February Revolution, Tsar Nicholas II abdicated, ending the Romanov dynasty’s centuries-long rule. The list spans ancient Rome to the modern era, but its events share a sense of transition: authority is challenged, institutions change, and an invention moves from novelty toward everyday use. Falling in early spring in the Northern Hemisphere, March 15 also arrives in a season associated with change—an apt backdrop for a date marked by both abrupt breaks and developments that unfold over time.
