 Fearing competition from the kingdoms of Luwu and Bone to the north and Sidareng and Sawitto to the south, Tiku worked on reinforcing his country's defences. The kingdoms eventually reached several trade agreements. However, Buginese encroaches led to renewed tensions between the states, climaxing in the Coffee War (Perang Kopi) in 1889. Tiku sided with the Buginese-influenced southern kingdoms.
