Officially, Bolivia is a Roman Catholic country, with over half of its residents claiming Catholicism as their primary religion.  Until a constitutional change in 1947, all other religions were prohibited.  The Catholic Church in Bolivia has an archbishop in La Paz, although the cardinal archbishop is in Sucre.  Unlike many Catholic imperialistic countries, the church in Bolivia has a relatively weak influence of politics, as evidenced by the fact that since 1911 all marriages have had to be performed by civil authorities in order to be legally valid. 

A majority of the Indigenous people are only superficially Catholic, as they still maintain loyalty to the pre-Columbian gods of their ancestors.  The existance of their beliefs in the spirit world is evidenced by the Witches Market, which sells all sorts of unusual items for use in potions, spells, and remedies.

Over the last decade, various Protestant misionary groups have worked in Bolivia, one of the more prominent being the Seventh Day Adventists.  These groups have aided the poorer indigenous groups with medical help and hospital maintainence.
