If Obote hadn't abolished kingdoms in 1967, it's unlikely that Olimi Kaboyo, who was already king, would have waited until 1987 to get married. Even Muwenda Mutebi wouldn't have waited until the late 1990s to get married. The pressure from their subjects would have ensured they got married before turning 40. They couldnt marry while in exile because it's an abomination for a king or a crown prince to do that.
If they had married early, succession would be unfolding differently. Maybe it would be less messy, maybe it would be more messy. The point is not to miss Obote's footprint in the current issues.
