There is evidence to suggest that the Earth government is beginning to move to a Psi-corps controlled totalitarian regime. It would appear that we humans have not made a whole lot of progress by the mid-23rd century. Earth Alliance is still recovering from a devastating war with the Minbari which raged for 4 years. The war started when during a first contact with the Minbari an Earth ship mistook a friendly gesture for a hostile act and fired. The Minbari ship, although vastly more powerful, had no defences active and was destroyed.
Minbari society is shrouded in mystery.
What is known is that there are three castes of Minbari, a warrior caste, a religious caste and a worker caste. The worker caste is the least influential section of Minbari society, they are often excluded from important discussions and negotiations. The religious caste wields the most power, though this appears to be changing in favour of the warrior caste. The warrior caste consists of five clans of Minbari, The Star Riders, The Wind Swords, The Moon Shields, The Night Walkers and The Fire Wings. The Minbari government is led by an organisation known as the Grey Council on which three Minbari from each caste sit.
