Drowning is the Leading Cause of Death. Drowning is the number one cause of death in abandoned mines. Most people involved in this type of accident went to a quarry for swimming.

The most noticeable characteristic is the degree to which nation states use the state as an instrument of national unity, in economic, social and cultural life. The nation state promoted economic unity, by abolishing internal customs and tolls.The internal diversity of the Ottoman Empire, for instance, was very great.)

Characteristic of nationalism are ideas of national superiority and national exclusiveness, which are developed to a greater or lesser degree, depending on the historical situation and the relations of a particular nation with other nations.
