The Most Important Events That Changed History Forever

Marriage Equality in the U.S. (2015)

Same-sex marriage was made legal nationwide with the Obergefell v. Hodges decision. On June 26, 2015, the Supreme Court struck down all state bans on same-sex marriage, legalized it in all fifty states, and required states to honor out-of-state same-sex marriage licenses. The first state to legalize same-sex marriage was Massachusetts on May 17, 2004.

Production of Penicillin (1928)

In 1928, bacteriologist Alexander Fleming determined that Penicillium Rubens had antibacterial properties. At the time, mass drug development was nearly impossible, leading to the initial dismissal of his discovery. However, after medical applications were established, a team at Oxford was able to produce penicillin in their laboratory. By the summer of 1945, over 646 billion units per year were in production.
