At certain points in the game, if the population of a city has been well provided for and are happy, a city-wide celebration will occur in that city, called "We Love the King Day" (or Emperor, or Regent, or President, etc.). The provisions for this to occur are: The city cannot be starving, The city cannot have any resisters, The city cannot have any unhappy citizens, There must be more happy citizens than content citizens, and The city must be large enough (typically size 6). The benefits of having a "We Love the __ Day" celebration are: The chance of the city converting to another civ is halved, Waste in the city is reduced, and The effectiveness of enemy spy propaganda missions against the city is reduced.
