The Pyu were the first to in recorded history to populate the area of Sagaing Region by the 1st century CE. The Burmans first migrated into Upper Myanmar by 9th century CE. The area came under the Pagan Kingdom certainly by the middle of 11th century when King Anawrahta (r. 1044–1077) founded the Pagan Empire, which encompasses the modern day Myanmar.

After the fall of Pagan in 1287, the northwestern parts of Upper Myanmar came under the Sagaing Kingdom (1315–1364) ruled by Burmanized Shan kings. The area was ruled by the kings of Ava from 1364 to 1555 and the kings of Taungoo from 1555 to 1752. Konbaung Dynasty (1752–1885), founded by king Alaungpaya in Shwebo, became the last Burmese dynasty before the British conquest of Upper Burma in 1885. The area became Sagaing Division after the Burmese independence in January 1948.
