Tenshō Iga War
is the name of two invasions of Iga province by the Oda clan during the Sengoku period. The province was conquered by Oda Nobunaga in 1581 after an unsuccessful attempt in 1579 by his son Oda Nobukatsu.

Background Geographically, the Iga region was surrounded by mountains on all sides that could be passed through only via narrow pathways. This, plus the distance of the region from major transportation routes, meant that Iga was easily defendable by a relatively small number of men and was not a priority target for outside forces. The Niki clan had served as shugo of the province for the Ashikaga shogunate, but their control had never been strong and soon weakened further as the shōgun's authority diminished. No great warlord rose to take their place, although the Rokkaku to the north and the Kitabatake to the east extended their influ ...

Voluntary Association
A voluntary group or union (also sometimes called a voluntary organization, common-interest association, association, or society) is a group of individuals who enter into an agreement, usually as volunteering, volunteers, to form a body (or organization) to accomplish a purpose. Common examples include trade associations, trade unions, learned society, learned societies, professional associations, and environmental movement, environmental groups. All such associations reflect freedom of association in ultimate terms (members may choose whether to join or leave), although membership is not necessarily voluntary in the sense that one's employment may effectively require it via occupational closure. For example, in order for particular associations to function effectively, they might need to be mandatory or at least strongly encouraged, as is true of trade unions. Because of this, some people prefer the term common-interest association to describe groups which form out of a common i ...
