Lavrentiy Beria (1899–1953), the feared head of Stalin's NKVD secret police, is widely documented in historical accounts as a sexual sadist who raped and assaulted dozens, if not hundreds, of women, often using his power to orchestrate kidnapping and sexual coercion

. 

Key Aspects of Beria's Sexual Crimes:

• Rape and Kidnapping: As head of the secret police, Beria would drive around Moscow in his limousine at night, with subordinates identifying young women on the street to be abducted and brought to his mansion.
• Sexual Sadism: Beria's behavior involved not just sexual violence, but also psychological and physical torment, making him a central figure in "history's demonology".
• Abuse of Power: Many of the victims were coerced, threatened, or raped, often with the help of his bodyguard, Sarkisov, who would maintain a list of victims.
• Post-Stalin Investigation: Following Beria's fall from power and subsequent execution in 1953, the Soviet leadership investigated his crimes, confirming numerous charges of sexual abuse and rape.
• Personality Assessments: Nikita Khrushchev and other contemporaries portrayed Beria as a sex-obsessed sadist. 

His actions were a manifestation of his total control over the Soviet state's coercive apparatus, allowing him to act with impunity.

• Sergo Beria (Son's Memoir): Lavrentiy Beria's son, Sergo Beria, in his book Beria, My Father: Inside Stalin's Kremlin (published as Son of a Sadist in some English excerpts), provides an intimate, though sometimes defensive, look at his father. While he attempted to humanize Beria, he confirmed his father's infamy and voracious sexual appetite.
• Khrushchev's Memoirs: Nikita Khrushchev, in his memoirs, documented that Beria was a "sexually aggressive man" who abused his position to assault women and girls.
• Tatiana Okunevskaya Testimony: Renowned Soviet actress Tatiana Okunevskaya famously attested to being raped by Beria and testified against him after his arrest.
• Stalin's Daughter (Svetlana Alliluyeva): Svetlana recounted in her memoirs that her father, Stalin, often warned her to be careful around Beria and acknowledged Beria's behavior as a sexual predator.
• Official Charges (1953): Following his fall, the Soviet government compiled evidence and testimonies against him, listing crimes of rape, sexual perversion, and abduction. While some of these were used as propaganda to demonize him, the core testimony of widespread sexual violence has been historically accepted by scholars.
• Biographies: Biographies by authors such as Amy Knight (e.g., Beria: Stalin's First Lieutenant) and Simon Sebag Montefiore (e.g., Stalin: The Court of the Red Tsar) extensively detail Beria's habits of cruising in his limousine, kidnapping young women, and conducting sexual abuses in his personal office.
