By the late nineteenth century, the Bubi were protected from the demands of the planters by Spanish Claretian missionaries, who were very influential in the colony and eventually organised the Bubi into little mission theocracies reminiscent of the famous Jesuit reductions in Paraguay. Catholic penetration was furthered by two small insurrections in 1898 and 1910 protesting conscription of forced labour for the plantations. The Bubi were disarmed in 1917, and left dependent on the missionaries. Serious labour shortages were temporarily solved by a massive influx of refugees from German Kamerun, along with thousands of white German soldiers who stayed on the island for several years.
