The Sophisticated Southeastern Region has a long and rich history within the archives of Sigma Gamma Rho Sorority, Inc. The history of the Southeastern Region began at the 14th Boule that convened in New York, New York. This Boule took place from December 27-30, 1939. This Boule was instrumental because this was the Boule where the Regions within Sigma Gamma Rho Sorority, Inc. were established. 

​

The acceptance of the regions was a sign of the growth of the sorority and the national membership advancements that led to this decision. Before this decision, there were only two regions within Sigma Gamma Rho Sorority, Inc. this move led to four regions. This decision also led to the creation of the Regional Syntaktes that leads each of the regions.
