Kabaka Bugunda

Kabaka, sometimes spelled as Kubaka, Bugunda was a Human male who lived in the 23rd century. 

By 2264, Kabaka and Nyota Uhura were deeply involved romantically. However, when Uhura announced she had accepted a promotion to communications officer aboard the USS Enterprise (NCC-1701), Kabaka presented a wedding ring to her and proposed marriage to her if she agreed to remain behind on Earth. Although Uhura loved Kabaka she didn't want to abandon her career and rejected his proposal. Unwilling to wait for Uhura to return, Kabaka threw the ring aside and walked out of Uhura's apartment.
