Founded as several colonies as part of the British Empire, the political geography is complicated by the fact that during colonization no treaties or conquests of First Nations (the indigenous people) occurred outside of a few small areas of the province. The resulting legal and political system is based upon the British, and later Canadian state that evolved from it. At present much of the province is subject to contested title and political rights with First Nations. The issue used to be called the Indian Land Question, though the term is no longer used. On-going disputes have included protest, political activity and legal challenges, including the recent

Local government
In the case of municipal-type services, there are municipalities, which are incorporated areas, and regional districts, which are groups of member municipalities and rural areas. Another purpose is for the provision of provincial services. The provincial government has dividing certain services into regional services, such as health authorities and agricultural commissions, which administer specified regions according to their own policies. The province is also divided to provide electoral districts by Elections BC for provincial elections and Elections Canada for federal elections. In addition to these, Indian Reserves have been established throughout the province but are administered by the federal government.
In order to fund community-wide services, such as a sewer system, urban areas incorporate to form municipalities. The vast majority of British Columbians live in these municipalities but there are also large areas of unincorporated rural areas around the municipalities. In 1964 the provincial government created regional districts, through amendments to the Municipal Act, to better coordinate regional issues and provide community services to unincorporated areas. Only one area, the sparsely populated Stikine Region in northwest B.C., is not covered by a regional district and municipal-type powers are administered directly by the provincial government.
