Xi Mu Zeta Chapter was chartered in 1989 by twenty-two women linked by a common goal to support their community and to uphold the ideals of Zeta Phi Beta Sorority, Incorporated.  The chapter, based in Markham, Illinois, provides community service throughout Markham and other south suburbs as well as the Chicago Metropolitan area.

Honoring it's commitment to women, in 1989 Xi Mu Zeta adopted the Family Rescue Shelter - a shelter for victims of domestic violence and their children. Chapter members coordinate monthly workshops on health, beauty and employment to assist the women's transition back to normal lifestyles. The chapter also brings cheer to families living at the shelter during the holidays.

The chapter actively supports the efforts of local and national organizations - including the Bottomless Closet,  Salvation Army, the NAACP, the Sickle Cell Disease Association of Illinois (SCDAI), the March of Dimes and the College Fund/UNCF.

Xi Mu Zeta Chapter believes in community involvement among youth and adults. The chapter established the Amicette Club, the Archonette Club, and the Amicae Auxiliary to help accomplish greater community service goals. 

Since it's inception, Xi Mu Zeta Chapter's achievements have been applauded. During it's first year, the chapter received the Fred Hampton Scholarship Image Award for outstanding community involvement. Since then, the chapter has received many other certificates of merit.
