Final answer:
The exact date when the sorority became an incorporated national organization depends on the specific sorority referred to, with Alpha Kappa Alpha being a notable example founded in 1908. To determine the correct date, the name of the specific sorority is required.
Step-by-step explanation:
The sorority referred to in the question likely became an incorporated national organization on a specific date, which appears to be missing from the question. To provide a precise answer, it is essential to know the exact sorority being referenced, as different sororities were incorporated on different dates. However, one of the most renowned sororities, Alpha Kappa Alpha, was founded in 1908 at Howard University and is known as the first Black women's intercollegiate Greek organization. Significant figures such as Kamala Harris and Toni Morrison are among its notable members.
Understanding the history of these organizations, including fraternity and sorority developments, is essential to appreciate their impact on social structures, professional networking, cultural significance, and risks such as the increased potential for sexual assault and sexual violence amongst members, as reported in various studies. Lawrence Ross's 'The Divine Nine: The History of African American Fraternities and Sororities' would be an excellent resource for detailed information on the specific dates and the overall contributions of these organizations.
