Caraga
On February 23, 1995, the Caraga region was created through the issue of Republic Act No. 7901 during the administration of President Fidel Ramos. The provinces of Agusan del Norte, Agusan del Sur and Surigao del Norte (of the former Northern Mindanao region) and Surigao del Sur (of the former Southern Mindanao region) were annexed as part of the newly-created region.
Surigao del Sur
Ancient province of Surigao extended from what is known as "Agusan", including the islands east of it and the northern regions of Davao and the capital of the province that time was Caraga and so the Spaniards called the people Caragas.
