History of the Isle of Man

The Isle of Man had become separated from Britain and Ireland by 6500 BC. It appears that colonisation took place by sea sometime during the Mesolithic era (about 6500 BC). The island has been visited by various raiders and trading peoples over the years. After being settled by people from Ireland in the first millennium, the Isle of Man was converted to Christianity and then suffered raids by Vikings from Norway. After becoming subject to Norwegian suzerainty as part of the Kingdom of Mann and the Isles, the Isle of Man later became a possession of the Scottish and then the English crowns.

Since 1866, the Isle of Man has been a Crown Dependency and has democratic self-government.

The Isle of Man effectively became an island around 8,500 years ago at around the time when rising sea levels caused by the melting glaciers cut Mesolithic Britain off from continental Europe for the last time. A land bridge had earlier existed between the Isle of Man and Cumbria, but the location and opening of the land bridge remain poorly understood.

The earliest traces of people on the Isle of Man date back to the Mesolithic Period, also known as the Middle Stone Age. The first residents lived in small natural shelters, hunting, gathering and fishing for their food. They used small tools made of flint or bone, examples of which have been found near the coast. Representatives of these artifacts are kept at the Manx National Heritage museum.

The Neolithic Period marked the coming of farming, improved stone tools and pottery. During this period megalithic monuments began to appear around the island. Examples are found at Cashtal yn Ard near Maughold, King Orry's Grave in Laxey, Meayll Circle near Cregneash, and Ballaharra Stones in St John's. The builders of the megaliths were not the only culture during this time; there are also remains of the local Ronaldsway culture (lasting from the late Neolithic into the Bronze Age) and also that of Bann.
