Lambda Theta Phi Latin Fraternity, Inc. was founded on December 1, 1975, at Kean College in Union, New Jersey by a group of ten men of Cuban, Puerto Rican, and Ecuadorian descent.

The founders of Lambda Theta Phi recognized a need to unite Latino students, nurture their leadership skills, emphasize the importance of education, and foster a commitment to community and culture.

[3][4] Lambda Theta Phi has achieved several milestones, including becoming the first Latin fraternity to join the National Interfraternity Conference (NIC) in 1992.

[7] In 2017, Lambda Theta Phi was suspended after allegations of underage drinking, hazing, and sexual assault surfaced at the University of Central Florida.

[8] Reports indicated that pledges were coerced into exhausting physical and mental exercises while being subjected to fraternity chants containing racial slurs and threats of violence.

The new members were reportedly required to wear uniforms, were prohibited from leaving or eating outside the location, and had to pay additional costs for this forced living arrangement.

[11] The individual was accused of physically assaulting a pledge who failed to complete push-up exercises, leading the victim to quit the fraternity.
