¶ Reform
Put all of your action cubes (one at least) on the city area - it is your last turn this round. Perform one out of three possible actions:
¶ Choose the government and religion
The government sets the direction of your development and defines your short-term and long-term goals. Also every government provides discounts for a number of technologies associated with it.
Choose one of three governments: Autocracy, Democracy or Theocracy. Place this government card face up in your player zone.
Choose one of four religions: Christianity, Islam, Buddhism or Paganism. Place one token of the chosen religion on your starting province, and another one - on your government card.
¶ Change the government
Discard all the experience cubes from the card of your old government and get 
for each cube discarded. Take this card back to your hand. Instead, place the new government card to your player zone.
¶ Change the religion
Discard the tokens of the previous religion from your starting province and your government card, and put tokens of the new religion instead. Other provinces under the influence of your old religion are not converted to the new religion, but you can spread your new religion to those provinces again in your next turn.
If you borrow a religion, meaning you convert to the religion that the other player has, you have to pass the check

. Pay this player as many , as many black cubes you have drawn from the bag. It is a bribe. If the religion you are converting to is followed by multiple players, the bribe must be paid to the Spiritual Leader of that religion.
In rare cases, if during the check you draw more black cubes than expected and cannot pay the bribe, then you cannot change your religion. This means you have failed and wasted action cubes, but you can still perform any remaining free actions and then end your turn.
