During Ottoman rule, Tomorrica was a subdistrict of Skrapar. At the time of early Ottoman rule, Tomorrica had about 500 able-bodied warriors, who frequently revolted against the Porte. In 1570, a major revolt was led by Hamza-Bey from Gramshi. The town of Gramsh bloomed in the 16th century with 400 houses and 18 shops, and was the place of residence of important beys and spahis who ruled over lands faraway in Fier, Berat, Korca, and even in Macedonia and Greece. Gramsh thus became famous not just locally, but also in the high spheres of the Ottoman Empire during this time. It was during this time that the famous Architect Kasemi lived and was chief architect of the Ottoman Empire. Later however, fortunes declined, and the loss of properties in Greece due to the Greek War of Independence was a major blow. Around the same time, the famous Frasheri family moved from Tomorrica to Dangellia, while blood feuds were taking place. Another wave of emigration out of Tomorrica occurred in the 18th century with hundreds of families leaving. Locals fled the area and settling in Perrenjas, Mazreke in Korca County, Krushevo in Macedonia, as well as among the Arberesh populations in South Italy and Greece. At the end of the Ottoman Empire, two chetas affiliated with the Albanian nationalist guerrilla fighter Sali Butka were active in Tomorrica. The Albanian Resistance hid out in Tomorrica during World War II. Mount Tomorr has been the object of a significant reverence and a historical cult among Albanians, said to have pagan origins. This caused many to travel to the region historically as part of their pilgrimages to Tomorr. The cult of Tomorr was incorporated into the Bektashi faith as a syncretic element, and a Bektashi tekke stands at the top of the mountain. Tomorr was especially revered in the regions that it was visible from, which include Tomorrica itself as well as Skrapari, Dishnica, Dangellia, Myzeqeja, Sulova, Mallakastra as well as others. On August 20–25, there is a festival by which hundreds of thousands of people climb the mountain, with people of all faiths participating, and in some cases coming from places as far as Macedonia, Montenegro and Kosovo to join in.
