Because of the discriminatory practices and lack of appeal of many predominantly White Greek-letter organizations, students of color sought the development of their own. Alpha Phi Alpha, Rho Psi, MALIK Sigma Psi, Lambda Theta Phi, and Alpha Pi Omega set the stage for later African American, Asian, African, Latino and American Indian Greek-letter organizations respectively. In addition, the gay, lesbian, bisexual and transgender community broke a barrier by forming Delta Lambda Phi as a fraternity that does not discriminate on the basis of sexual orientation.
