What happened November 1985 AD

Spielberg first met actress Amy Irving in 1976 at the suggestion of director Brian De Palma, who knew he was looking for an actress to play in Close Encounters. After meeting her, Spielberg told his co-producer, Julia Phillips, "I met a real heartbreaker last night." Although she was too young for the role, she and Spielberg began dating and she eventually moved into what she described as his "bachelor funky" house. They lived together for four years, but the stresses of their professional careers took a toll on their relationship. Irving wanted to be certain that whatever success she attained as an actress would be her own: "I don't want to be known as Steven's girlfriend," she said and chose not to be in any of his films during those years. As a result, they broke up in 1979 but remained close friends. Then in 1984, they renewed their romance, and on November 1985, they married, already having had a son, Max Samuel.

On November 6, 1985, the M-19 stormed the Colombian Palace of Justice and held the Supreme Court magistrates hostage, intending to put president Betancur on trial. In the ensuing crossfire that followed the military's reaction, some 120 people lost their lives, as did most of the guerrillas, including several high-ranking operatives and 12 Supreme Court Judges. Both sides blamed each other for the outcome. This marked the end of Betancur's peace process.

The Armero tragedy was one of the major consequences of the eruption of the Nevado del Ruiz stratovolcano in Tolima, Colombia, on November 13, 1985. The lahars picked up speed in gullies and engulfed the town of Armero, killing more than 20,000 of its almost 29,000 inhabitants. Casualties in other towns, particularly Chinchiná, brought the overall death toll to 23,000.
