Authorities differ over the facts of its founding. Mordechai Abir states that it was founded by Ras Ali I; however, Richard Pankhurst gives a detailed account of its foundation by Ras Gugsa, and includes the tradition that the location was selected with supernatural help. In either case, Debre Tabor was the seat of the Regents of the Emperor in the 18th and 19th centuries, from which periods several churches and the ruins of two palaces survive. Debre Tabor was the capital of Ethiopia under two Emperors: Tewodros II, before he moved the capital to Magdala; and Yohannes IV. As a result, in the 19th century the population of this town varied depending on whether the emperor was in residence. If he was present, the population could reach 30,000 as it did under Emperor Yohannes; if he was not, it would be around 5,000 people.

The Battle of Debre Tabor was fought nearby on February 6, 1842; although Dejazmach Wube Haile Maryam and his allies defeated the armies of Ras Ali II and sacked Debre Tabor once again, they were surprised while celebrating their victory by Birru Aligas, an ally of Ras Ali, who captured Wube and his son and extracted concessions from them in return for their release. Ras Ali built four churches in Debre Tabor: Iyasus on the mountain to the southeast, Ennatitu Maryam and Legitu Maryam to the east, and Tegur Mikael to the north. A second palace was built for his mother, the Empress Menen Liben Amede, which was not as large as Ras Ali's. '', 1868. Although he burnt the town in May 1853, following Ras Ali's defeat, Emperor Tewodros used Debre Tabor as his capital until his situation weakened so badly that he was forced to abandon the town for his stronghold on Maqdala. The Emperor Yohannes IV often resided at Debre Tabor, and during his reign Heruy Giyorgis church was built. Here the Emperor met with General Gordon in October 1878, who was representing the Egyptian government, about Ethiopian demands for access to the Red Sea. It was also in Debre Tabor that Tekle Haymanot was crowned Negus of Gojjam in January 1881.
20th Century
When the Bank of Ethiopia was created in 1931 it opened a branch office with two employees at Debre Tabor. During the Second Italian-Abyssinian War, Debre Tabor was occupied by unit which advanced from Bahir Dar on 28 April. During the occupation, a telegraph office was opened in the town and postal service restored. The Italians also constructed a road from Gondar via Debre Tabor to Dessie. The first mosque in Debre Tabor was constructed and eucalyptus planting extended. Despite these improvements, as early as August 1937, there were almost simultaneous but apparently uncoordinated attacks by arbegnoch on garrisons near Debre Tabor and near Bahir Dar. After several months of attacks, the British convinced Colonel Angelini to surrender the town 6 July 1941, allowing the British to advance towards the organized Italian resistance around Gondar under the command of Guglielmo Nasi, who by this point was the acting Viceroy and Governor-General of Italian East Africa. In 1958, Debre Tabor was one of 27 places in Ethiopia ranked as First Class Township.

Government control was reestablished within a month. In late December 1989, Tigray People's Liberation Front forces captured Debre Tabor, claiming that they killed or wounded more than 8,000 government troops. Around 20 January 1990, the Ethiopian News Agency announced that government forces had recaptured Debre Tabor. A few days later, the clandestine radio of the TPLF claimed a major victory in battles near Debre Tabor on 22–24 January 1990, claiming their soldiers had killed 3,914 government troops and captured 270. Although the town was retaken by government troops a few days later, the TPLF, announced the recapture of the town after a three-day battle in late February.
