According to frederick jackson turner why did english ideas about government change

According to Frederick Jackson Turner, the change of a stable and civilized way of life in European cities, towards the change of life in the prairies, in wild territory, produced in the Colonists an emergence of the adventurous spirit, full of a new vitality , and formed that American spirit so different from the British. This meant that independence was necessary to develop self-sufficiency and individualism, to advance in a frontier and wild territory. However, over the years, he changed his point of view, and thought that it was necessary to return to a systematized and organized way of life, to ensure that resources would last.
