Background: Usama ibn Mohammed ibn Awad ibn Ladin (Arabic: 'sm@ bn mHmd bn `wD bn ldn, usamah ibn muhammad ibn 'awad ibn ladin), often anglicized as Osama bin Laden (; March 10, 1957 - May 2, 2011), was a founder of al-Qaeda, the organization responsible for the September 11 attacks in the United States and many other mass-casualty attacks worldwide. He was a Saudi Arabian until 1994 (stateless thereafter), a member of the wealthy bin Laden family, and an ethnic Yemeni Kindite. Bin Laden's father was Mohammed bin Awad bin Laden, a Saudi billionaire from Hadhramaut, Yemen. His mother, Alia Ghanem, was from a secular middle-class family based in Latakia, Syria.
Context: There is no universally accepted standard for transliterating Arabic words and Arabic names into English; however, bin Laden's name is most frequently rendered "Osama bin Laden". The FBI and Central Intelligence Agency (CIA), as well as other U.S. governmental agencies, have used either "Usama bin Laden" or "Usama bin Ladin". Less common renderings include "Ussamah bin Ladin" and, in the French-language media, "Oussama ben Laden". Other spellings include "Binladen" or, as used by his family in the West, "Binladin". The decapitalization of bin is based on the convention of leaving short prepositions, articles, and patronymics uncapitalized in surnames; the nasab bin means "son of". The spellings with o and e come from a Persian-influenced pronunciation also used in Afghanistan, where bin Laden spent many years.  Osama bin Laden's full name, Osama bin Mohammed bin Awad bin Laden, means "Osama, son of Mohammed, son of Awad, son of Laden". "Mohammed" refers to bin Laden's father Mohammed bin Laden; "Awad" refers to his grandfather, Awad bin Aboud bin Laden, a Kindite Hadhrami tribesman; "Laden" refers not to bin Laden's great-grandfather, who was named Aboud, but to Aboud's father, Laden Ali al-Qahtani.  The Arabic linguistic convention would be to refer to him as "Osama" or "Osama bin Laden", not "bin Laden" alone, as "bin Laden" is a patronymic, not a surname in the Western manner. According to bin Laden's son Omar bin Laden, the family's hereditary surname is "al-Qahtani" (Arabic: lqHTny, al-Qahtani), but bin Laden's father, Mohammed bin Laden, never officially registered the name.  Osama bin Laden had also assumed the kunyah "Abu 'Abdallah" ("father of Abdallah"). His admirers have referred to him by several nicknames, including the "Prince" or "Emir" (l'myr, al-Amir), the "Sheik" (lshykh, as-Saykh), the "Jihadist Sheik" or "Sheik al-Mujahid" (shykh lmjhd, Saykh al-Mujahid), "Hajj" (Hj, Hajj), and the "Director". The word usamah ('sm@) means "lion", earning him the nicknames "Lion" and "Lion Sheik".
