In this paper the author analyses 17 pieces from the Great Migrations period that make part of the private collection belonging to the archeologist Mato Ilkić. All the objects were found in Sotin near Vukovar, on the site of Vrućak. The greatest part of them can be dated in the Second Avar period (from the first half of the 8th to the beginning of the 9th century). One object - the damaged arch-shaped fibula - can be dated in the second half of the 5th century and can be attributed to Germans. The author opines that it is not possible to give precise ethnic and chronological determination for three S-buckles. He supposes that they might have belonged to the indigenous romanized population and dates them in the period from 6th to the end of the 7th century. The analysis of these finds represents the new contribution for the study of topics concerning The Great Migrations period in Croatia. Also, it installs Sotin as one of the most important sites with the Second Avar period material in that area.
