Roe v. Wade, the landmark Supreme Court decision that established a woman’s legal right to an abortion, is decided on January 22, 1973. The Court ruled, in a 7-2 decision, that a woman’s right to choose an abortion was protected by the privacy rights guaranteed by the Fourteenth Amendment to the U.S. Constitution.

The United States, South Vietnam, Viet Cong and North Vietnam formally sign “An Agreement Ending the War and Restoring Peace in Vietnam” in Paris. Due to South Vietnam’s unwillingness to recognize the Viet Cong’s Provisional Revolutionary Government, all references to it were confined to a two-party version of the document signed by North Vietnam and the United States—the South Vietnamese were presented with a separate document that did not make reference to the Viet Cong government. This was part of Saigon’s long-time refusal to recognize the Viet Cong as a legitimate participant in the discussions to end the war.

A cease-fire in the Vietnam War goes into effect at 8 a.m., Saigon time (midnight on January 27, Greenwich Mean Time).

On March 11, 1973, the first formal meeting of “Parents of Gays,” co-founded by the parents of a gay son, is held in a church in Greenwich Village in New York.

On March 17, 1973, Associated Press photographer Slava “Sal” Veder captures a heartwarming scene on the tarmac of California's Travis Air Force Base as a recently freed American prisoner of war runs toward his family.

The photo depicting Lt. Col. Robert L. Stirm and his family, called “Burst of Joy,” goes on to win a Pulitzer Prize in 1974.

On March 27, 1973, the actor Marlon Brando declines the Academy Award for Best Actor for his career-reviving performance in The Godfather.

The “Twin Towers” of the World Trade Center officially open in New York City. The buildings replaced the Empire State Building as the world’s tallest building.

On April 21, 1973, Tony Orlando and Dawn's “Tie a Yellow Ribbon Round the Ole Oak Tree,” tops the U.S. pop charts. The yellow ribbon has long been a symbol of support for absent or missing loved ones, but this song turned the tradition into a cultural phenomenon.

On May 13, 1973, during the early years of the women’s liberation movement, tennis stars Bobby Riggs and Margaret Court face off in a $10,000 winner-take-all challenge match. The 55-year-old Riggs, a tennis champion from the late 1930s and '40s who was notoriously skeptical of women’s talents on the tennis court, branded the contest a “battle of the sexes.” The match, which was played on Mother’s Day and televised internationally, was held on Riggs’ home turf, the San Vincente Country Club in Ramona, California, northeast of San Diego. Proceeds were promised to the American Diabetes Association.

On August 11, 1973, at a back-to-school party for teenagers in the recreation room of an apartment building in the west Bronx, New York City hip hop is born. Like any style of music, hip hop has roots in other forms, and its evolution has been shaped by many different artists. But there's a strong case to be made that it came to life precisely at this event, in a community room at 1520 Sedgwick Avenue. The man who presided over that historic party was the party giver's brother, Clive Campbell—better known to history as DJ Kool Herc, founding father of hip hop.

On August 11, 1973, the nostalgic teenage coming-of-age movie American Graffiti, directed and co-written by George Lucas, opens in theaters across the United States. Set in California in the summer of 1962, American Graffiti was nominated for five Academy Awards, including Best Director and Best Picture, and helped launch the big-screen careers of Richard Dreyfuss and Harrison Ford, as well as the former child actor and future Oscar-winning filmmaker Ron Howard.

The “Golden Bear” went on to win 18 major tournaments, a record that still stands today. (Although it aptly describes his golden-colored hair and large build, Nicklaus’ famous moniker is actually derived from his high school alma mater, the Upper Arlington Golden Bears.)

Chile’s armed forces stage a coup d’état against the government of President Salvador Allende, the first democratically elected Marxist leader in Latin America. Allende retreated with his supporters to La Moneda, the fortress-like presidential palace in Santiago, which was surrounded by tanks and infantry and bombed by air force jets.

On September 20, 1973, in a highly publicized “Battle of the Sexes” tennis match, top women’s player Billie Jean King, 29, beats Bobby Riggs, 55, a former No. 1 ranked men’s player. Riggs (1918-1995), a self-proclaimed male chauvinist, had boasted that women were inferior, that they couldn’t handle the pressure of the game and that even at his age he could beat any female player. The match was a huge media event, witnessed in person by over 30,000 spectators at the Houston Astrodome and by another 50 million TV viewers worldwide. King made a Cleopatra-style entrance on a gold litter carried by men, while Riggs arrived in a rickshaw pulled by female models. Legendary sportscaster Howard Cosell called the match, in which King beat Riggs 6-4, 6-3, 6-3. King’s achievement not only helped legitimize women’s professional tennis and female athletes, but it was seen as a victory for women’s rights in general.
