I. P. Vozny Migration Processes in the Territory of Northern Bukovina in the 13th — Early 15th Centuries The article discusses the migration processes in the territory of Northern Bukovina during the developed Middle Ages. This is the time of turbulent political events that subsequently influenced the further fate of the population inhabiting this territory. Local population developed in the mainstream of the evolution of ancient Rus lands. Intensive socio-economic development of the territory of Northern Bukovina in the 12th — early 13th century led to an increase in population and to episodic migrations. This picture changed in the late 13th—14th centuries. The Mongol-Tatar invasion negatively affected the development of the region. The population constantly suffered from the confrontation of Poland, Hungary, the Galicia-Volhynia principality, the Golden Horde and the Moldavian Voivodeship. Due to this (plus abnormal natural phenomena), these territories were sparsely populated. The majority of the population affected by the migration movement moved to the Prut-Siret interfluve or headed to the Carpathians. With the entry of this territory into the Moldavian Voivodeship, the situation changed. The domestic policy of the rulers and the change in the external international situation contributed to a significant re-emigration and re-settlement of the Prut-Dniester interfluve. Most settlements arise here in the late 14th — early 15th centuries. By the middle of the 15th century, the external reserves of colonization were exhausted, internal feuds intensified. All this led to a long decline in migration processes in the study area.
