The Trilfuva Province is one of the twelve provinces of Leubantia. Until 1962, it included the Leubantian capital, Trilfuva. However, Trilfuva is still the de facto capital of Trilfuva Province, as well as being the capital of the Leubantian Federal District. Its territory roughly coincides with that of the Duchy of Leubantia just after uniting with nearby city-states, but before annexing its eastern, southern and northern neighbours.
