The 1840s was a time of conflict where various Fiji clans attempted to assert dominance over each other. Eventually, a warlord named Seru Epenisa Cakobau of Bau Island was able to become a powerful influence in the region. His father was Ratu Tanoa Visawaqa, the Vunivalu (a chiefly title meaning warlord'','' often translated also as paramount chief) who had previously subdued much of western Fiji. Cakobau, following on from his father, became so dominant that he was able to expel the Europeans from Levuka for five years over a dispute about their giving of weapons to his local enemies. In the early 1850s, Cakobau went one step further and declared war on all Christians. His plans were thwarted after the missionaries in Fiji received support from the already converted Tongans and the presence of a British warship. The Tongan Prince Enele Maʻafu, a Christian, had established himself on the island of Lakeba in 1848, forcibly converting the local people to the Methodist Church. Cakobau and other chiefs in the west of Fiji regarded Maʻafu as a threat to their power and resisted his attempts to expand Tonga's dominion. Cakobau's influence, however, began to wane, and his heavy imposition of taxes on other Fijian chiefs, who saw him at best as first among equals, caused them to defect from him.
