Original: Guam , along with the rest of the Mariana and Caroline Islands , were treated as part of Spain 's colony in the Philippines . While Guam 's Chamorro culture is unique , the cultures of both Guam and the Northern Marianas were heavily influenced by Spanish culture and traditions during their 333 years of rule .
Simplified: Even though the Northern Mariana Islands were also taken over by America , they still feel different from the Chamorro people on Guam .
