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.
Davao Oriental
The present territory of Davao Oriental was covered by the historical region of Caraga, which was under the Sultanate of Maguindanao. The Spaniards established a permanent settlement in the region in 1591, and in 1844, the area was ceded by the Sultanate to Spain. An expedition was sent by the colonial government in Manila in 1847 to control the region, led by the Spaniard Jose Oyanguren, who settled in the town of Davao and organized the surrounding areas into the province of Nueva Guipozcoa in 1849. The province existed until 1858, when the politico-military "commandancia"s of Davao and Bislig were created in its place. Bislig was incorporated into the District of Davao two years later.
