The Great Replacement, also known as replacement theory or great replacement theory, is a debunked white nationalist far-right conspiracy theory coined by French author Renaud Camus. Camus's theory states that, with the complicity or cooperation of "replacist" elites, the ethnic French and white European populations are deliberately being replaced by non-white peoples—especially from Muslim-majority countries—through mass migration, demographic growth and a drop in the birth rate of white Europeans. Since then, similar claims have been advanced in other national contexts, notably in the United States. A consensus of academic scholars have dismissed these claims of a conspiracy of "replacist" elites as rooted in a misunderstanding of demographic statistics and premised upon an unscientific, racist worldview.

The death of Jeffrey Epstein, an American financier and child sex offender, occurred on August 10, 2019. Guards claimed to have found Epstein unresponsive in his jail cell at 6:30 a.m. at the Metropolitan Correctional Center in New York City, hanging off the side of his cell's bed, where he was awaiting trial on sex trafficking charges. After prison guards reportedly performed CPR, he was transported in cardiac arrest to the New York Downtown Hospital, where he was pronounced dead at 6:39 am. The New York City medical examiner and the Justice Department Inspector General ruled that Epstein's death was a suicide by hanging. Epstein's lawyers challenged the medical examiner's conclusion and opened their own investigation, hiring pathologist Michael Baden.
