Caraga
Caraga, officially known as the Caraga Administrative Region or simply Caraga Region and designated as Region XIII, is an administrative region in the Philippines occupying the northeastern section of the island of Mindanao. The Caraga Region was created through "Republic Act No. 7901" on February 23, 1995. The region comprises five provinces: Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur and Dinagat Islands; six cities: Bayugan, Bislig, Butuan, Cabadbaran, Surigao and Tandag; 67 municipalities and 1,311 barangays.

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.
