Skull and Bones

Skull and Bones, also known as The Order, Order 322 or The Brotherhood of Death, is an undergraduate senior secret student society at Yale University in New Haven, Connecticut. The oldest senior class society at the university, Skull and Bones has become a cultural institution known for its powerful alumni and various conspiracy theories. It is one of the "Big Three" societies at Yale, the other two being Scroll and Key and Wolf's Head.

The society's alumni organization, the Russell Trust Association, owns the organization's real estate and oversees the membership. The society is known informally as "Bones," and members are known as "Bonesmen," "Members of The Order" or "Initiated to The Order."

Skull and Bones selects new members among students every spring as part of Yale University's "Tap Day", and has done so since 1879. Skull and Bones selects fifteen students from the junior class to the junior class to join the society. Skull and Bones "taps" those that it views as campus leaders and other notable figures for its membership.

Women have been accepted as members since the early 1990s.
