February 21 brings together political argument, artistic expression and the struggle for civil rights. In 1848, Karl Marx and Friedrich Engels published *The Communist Manifesto* in London, putting a forceful political vision into print. Nina Simone, born in 1933, would use a very different medium: her music ranged across classical, jazz, blues and gospel, while her powerful voice addressed racial injustice in the United States. Across these events, words and performance emerge as ways of making ideas public—and challenging listeners to reckon with them.
The date also carries a stark reminder of the risks surrounding public speech: in 1965, Malcolm X was assassinated as he prepared to address a rally in New York City. These moments are not interchangeable, but together they trace how political and artistic voices can shape debates about power, justice and change. The list spans nearly 120 years, yet its events share an emphasis on people speaking to audiences beyond themselves. In late February, with winter still underway in much of the United States, the calendar offers no single seasonal mood; instead, this date looks back on enduring struggles over who gets heard and what their words can set in motion.
