Semeljci is located 13 kilometres (8.1 mi) east of Đakovo, and is bordered by Kešinci, Forkuševci and Koritna.

By 1758, Semeljci had grown to include 95 listed houses and was one of the largest villages that made up the Diocesan estate.

The increased number of people was the main reason that the village became the seat of the Catholic parish by 1754, and the church was enlarged.

[7] By the second half of the 19th century, Germans and Hungarians moved into Semeljci, making it a large and ethnically diverse village.

In 2005, the Croatian Chamber of Commerce awarded the Golden Kuna in the category of large enterprises to Semeljci for its achievements.
