The University’s Interfraternity Council welcomed a new fraternity Sept. 26.

Theta Chi became the 21st fraternity addition to campus when it received the necessary number of votes at the regularly scheduled Interfraternity Council meeting, Logan Davis, a graduate assistant at Greek Life said in an email.

Theta Chi, which started out as an interest group in April 2010 with 10 undergraduate men, was chartered as the Iota Pi chapter on April 21 with 45 members, according to a news release.

“The Interfraternity Council couldn’t be more excited to welcome the men of Theta Chi into the council,” Jonathan Sanders, associate director of Greek Life, said in the release.

Present at Wednesday’s vote were Theta Chi President Justin Jones, President of the Advisory Board of Theta Chi at LSU Steve Mannear, Graduate Adviser Eric Shapiro, and Theta Chi Executive Director Mike Mayer, who represented the International Headquarters.

Theta Chi is one of the oldest men’s college fraternities. According to the release, it was founded at Norwich University in Vermont on April 10, 1856, on the principles of friendship through every member mutually assisting one another.

Theta Chi has 131 active chapters across the nation, Davis said.

As a social fraternity, Theta Chi focuses on academics, service and involvement, he said.

The last addition to the IFC was in 2005 when the LSU chapter of Sigma Alpha Mu was founded.
