1. The date of February 27 marks the anniversary of the Battle of Albuquerque, which occurred in 1862 during the Civil War. Union troops, led by Colonel Edward Canby, successfully captured the city from Confederate forces after a two-day battle. The victory helped secure New Mexico as a Union territory during the war.

2. On February 27, 1913, the New Mexico State Legislature passed a resolution to ratify the 17th Amendment to the U.S. Constitution, which established the direct election of U.S. Senators by popular vote. New Mexico was one of the first states to ratify the amendment, which went into effect in 1914.

3. In 1915, the first meeting of the New Mexico State Police Commission was held on February 27. The commission was established to oversee the newly-formed State Police force, which was created to combat rural crime and enforce statewide laws.

4. February 27, 1925, marked the completion of the first motorized mail delivery in New Mexico. The mail truck, which traveled from El Paso to Santa Fe and back, carried over 2,000 pounds of mail and packages. This new mode of transportation greatly reduced the time it took to deliver mail between the two cities.

5. On February 27, 1973, the New Mexico Legislature approved the state's official flag design.
