Samahang Ilokano
The Confederation of Ilocano Association, Incorporated, Samahang Ilokano (CIAI-SI) or Samahang Ilokano (SI) is a fraternity and sorority composed of students from colleges and universities in the northern part of the Philippines. Members are either of Ilocano lineage and/or have the capability of speaking and understanding the Ilokano language. Samahang Ilokano was founded in the late 1940s as a fraternity to unite Ilocano speaking students. Ilocano speaking students from Northern Luzon provinces would pursue higher education in universities away from home and seek fellow Ilocanos for company and protection. Soon enough the fraternity grew in number, which  attracted scrutiny from other fraternities. Growth of member population also sparked uncontrollable brawls and riots, some of which landed members in prison. The Genuine Ilocano gills (GIG) was formed as a group for SI members who were incarcerated, and soon accepted members from within the prison. Power struggles within the fraternity led to further separation of members. Hence, the birth of another faction now known as United Ilocandia Fraternity/Sorority (UI). The lack of organization created tension between the three groups Unity and expansion. During martial law, the leaders and founders of the different groups agreed to unite the three  organizations. This led to the creation of an umbrella organization, registered with the Securities and Exchange Commission under the name "Confederation of Ilocano Association, Incorporated" as a non-stock, non-profit and non-dividend corporation. Members of UI and GIG often do not use CIAUI or CIAGIG, and instead prefer their respective original faction names. Most members of CIASI became professionals, which gave the opportunity for the group to diversify into factions of the following types within the organization: international, military, professional, women's auxiliary, out-of-school youths, and students. Despite significant changes within the structure, the ultimate purpose  of the Samahang Ilokano still stands: "an organization to cradle the Ilocanos".
