[4] Knowledge of navigation was well developed at this time and reached a peak of skill not exceeded until a method was discovered (or perhaps rediscovered) to determine longitude around AD 1750.
Their syllabic script, the Linear B, offers the first written records of the Greek language and their religion already included several deities that can be also found in the Olympic Pantheon.
Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace states that developed rigid hierarchical, political, social and economic systems.
Some very rich burials, such as the one located at Leubingen (today part of Sömmerda) with grave gifts crafted from gold, point to an increase of social stratification already present in the Unetice culture.
Sanctuaries and larger settlements were also built starting from the late second millennium BC to host these religious structures along with other structures such ritual pools, fountains and tanks, large stone roundhouses with circular benches used for the meeting of the leaders of the chiefdoms and large public areas.
The Nuragic civilization survived throughout the early Iron Age when the sanctuaries were still in use, stone statues were crafted and some Nuraghi were reused as temples.
In northern Germany, Denmark, Sweden and Norway, Bronze Age cultures manufactured many distinctive and artistic artifacts.
Recent tooth enamel isotope research on bodies found in early Bronze Age graves around Stonehenge indicate that at least some of the immigrants came from the area of modern Switzerland.
Additionally, the climate was deteriorating; where once the weather was warm and dry it became much wetter as the Bronze Age continued, forcing the population away from easily defended sites in the hills and into the fertile valleys.
Large livestock ranches developed in the lowlands which appear to have contributed to economic growth and inspired increasing forest clearances.
Cornwall was a major source of tin for much of western Europe and copper was extracted from sites such as the Great Orme mine in northern Wales.
The greatest quantities of bronze objects found in England were discovered in East Cambridgeshire, where the most important finds were done in Isleham (more than 6500 pieces).
[20] Ecological degradation, landscape opening, fires, pastoralism, and maybe tree cutting for mining have been suggested as reasons for the collapse.
[21] The culture of the motillas, developed an early system of groundwater supply plants (the so-called motillas) in the upper Guadiana basin (in Iberian Peninsula's southern meseta) in a context of extreme aridification in the area in the wake of the 4.2-kiloyear climatic event, which roughly coincided with the transition from the Copper Age to the Bronze Age.
Increased precipitation and recovery of the water table from about 1800 BC onward should have led to the forsaking of the motillas (which may have flooded) and the redefinition of the relation of the inhabitants of the territory with the environment, with the development of the Iberian oppida mode of settlement.
The Bronze Age in Ireland commenced in the centuries around 2000 BC when copper was alloyed with tin and used to manufacture Ballybeg type flat axes and associated metalwork.
