Social Organization: The arrival of Jesuit missionaries in Cayubaba territory came rather late, together with the expedition led by Padre Agustín Zapata, in 1693. In 1704 Padre José Garriga established "Exaltación de la Santa Cruz", a mission that by 1840 would become Moxos, the capital during two years, until the foundation of the Department of the Beni, with its capital in Trinidad. Most of the regional rubber trade came down the Mamore River to the shipping port in Exaltación, soon turning the settlement into an active hub of trade. The Cayubaba people were recruited en masse to work the rubber plantations. Today they undergo a fast-paced process of ethnic extinction, and the composition of most their communities is multiethnic. The nuclear family is the prevailing pattern of marriages throughout their lands.

Political Organization: In the past, it used to be that the paititi or chief would hold the highest authority. Today, in spite of the great concentration of carayanas (whites) in the region, the traditional authority system is making a comeback. The Indigenous Cabildo (Council) is once more the seat of communal decisions, even in the planning of religious festivities. Thus, against all expectations, the Cayubaba are organizing their own affiliate to the CPIB, and therefrom to CIDOB.
