acquired territories was planned. This, and the process of disarmament of the local population, were key factors to the rise of the Kaçak guerilla movement. World War I and World War II During the First World War, most of the Serbian army, led by the Serbian king Peter I, retreated through the Llapi region. During the retreat, war crimes (including robbing, killing and destruction of property) took place. Llapi was later taken by Bulgaria, which, from time to time, organized grain and cattle requisition. Starting from 1916, any people were deported and sent to work in different countries, most of them never returning. After the Bulgarian surrender, Bulgarian soldiers killed a lot of people and robbed many places during their retreat. Albanians would later form their own military formations for a short period of two months. The region fell to Yugoslavian Kingdom. In the beginning, the Llapi region had 12 municipalities with 27.084 residents. Later, the number of municipalities was reduced. From 1929 to 1941, Podujevo was part of the Morava Banovina of the Kingdom of Yugoslavia; between the two World Wars, Albanians living in the region had no political rights. They were poor and heavily taxed, and corruption was evident in the administration. The main problem, however, was colonization, which Yugoslavia claimed to be agricultural reforms. The Albanian language was not used at all in public administration and schools, Many residents were forced to migrate to Turkey, while their land was given to Serbian and Montenegrin colonists who would eventually take 62% of infields. Even mosques were controlled by the state. Armed resistance was mostly pushed by Kaçak movements since it was impossible to organize large groups of people. They managed to expel the Serbian colonists, but the consequences were far greater, as in the beginning of 1921 many massacres against the Albanian population would occur. In Sharban, 35 people were killed and 28 houses were burned. In Bellopoja, 40 people were killed and 57 houses were damaged. In Keqekolla, 490 people were killed and 40 houses were burned.
