chapters See List of Phi Delta Theta chapters Since 1848, Phi Delta Theta has granted more than 285 charters across the United States and Canada. Today, there are over 191 active chapters and colonies. To be granted a charter, a colony must complete certain requirements set forth by the General Council. Chief among these are recruiting a certain number of members and achieving a respectable cumulative grade point average among its members. Phi Delta Theta also has the longest continuous chapter of any fraternity in the United States, that chapter being the Kentucky Alpha-Delta chapter at Centre College, which was established in 1850 and is still active today. The largest chapter of Phi Delta Theta is at Indiana University with, on average, 160 active brothers and has been active since 1849. Alumni chapters Currently, Phi Delta Theta has over 100 active alumni clubs. Although all the clubs are currently in North America, alumni clubs have been found all over the world throughout its history. At one point, there were over 165 alumni chapters, some as far away as China. The most Phis to ever assemble on foreign land for an alumni club meeting, before the fraternity became international in 1902, was in Manila, Philippines when 30 Phis gathered in 1899. The alumni club in the Philippines lasted for nearly 40 years.
