The emergence of hilltop settlements presents a pattern of the first enclosed sites that reflect economic development in several regions within the Southeastern Baltic Bronze Age. This novelty reflects increasing social complexity, differentiating economic relations, as well as rising tension in the region. The phenomenon has received a great deal of interpretation, but chronological problems still remain understudied. Researchers tend to seek the start of hilltop settling practice from early to late II millennium BC. This paper presents 14C dates from 7 sites in inland Lithuania, where hitherto no absolute dates were published. The majority of absolute dates has been calibrated to the Hallstatt radiocarbon calibration plateau (ca. 800–400 cal BC) which is significantly later than previously presumed based on dates from Belarusian sites. However, several dates from previously dated hilltop settlements in the region predate the effect. These results indicate the start of hilltop settling practice around 11th–9th centuries cal BC. Review of new and previously published radiocarbon dates suggests a different internal development between SE Baltic coastal and inland regions, likely locating zones, where economic outside stimulus preconditioning emergence of hilltop settlements occurred earlier.
