The notion of sister cities stems back to 1956 when President Dwight D. Eisenhower created Sister Cities International, a non-partisian (501(c)3 non-profit which serves as the national membership organization for individual sister city programs across the United States. It was created with the vision that a sister city citizen network would function as a champion for peace and prosperity between people from different communities around the globe.
Sister City relationships are official relationships established through formal agreements by the respective municipal governments. Houston’s sister city program is a volunteer-based program that works with the City of Houston to further the sister city relationships. Volunteers develop and implement programs and activities that connect the cities on mutually beneficial matters.
