When was Alpha Kappa Alpha incorporated?

Alpha Kappa Alpha was incorporated on January 29, 1913. This date is significant as it marks the formal establishment of the organization, which was founded by a group of college-educated women at Howard University in Washington, D.C. The incorporation of Alpha Kappa Alpha enabled it to gain legal recognition and solidify its intentions of promoting sisterhood, scholarship, and service among its members. This date is widely celebrated within the sorority and recognized as a pivotal moment in the history of Black Greek-letter organizations.

The other options present dates that are either prior to the official incorporation or are not associated with key events in the sorority's history, making them incorrect in this context.
