Villagers and Villages
Sometimes when you are exploring you will find small villages with a few buildings, inhabited by some rather weird-looking villagers. These villages occur in plains or desert biomes, with different building styles in each place.
Most of the buildings are homes, but you will also find a tavern (with a stone slab bar and a fenced-off garden), a blacksmith, a library and/or a church. There will also be farms growing wheat or other crops, and a well.
Tip: if you move into a village and want to use the well as a water source, place some blocks below the surface so the water is only 1 block deep.
Villagers are “passive mobs”, meaning that they will not fight you. You will encounter five types of villager: farmers (brown robes), librarians (white robes), priests (purple robes), blacksmiths (black aprons) and butchers (white aprons).
Villagers will wander around harvesting thei crops and looking at stuff during the day, and go home at night or when it’s raining. You can right-click on a villager to trade with him. Her. It.
Two things control the population of villagers; whether there is enough housing for them, and whether they are happy and willing to have babies.
Villagers will become willing after you trade with them. After they breed, you will need to trade again to keep them willing again.
Villagers will only get together and have babies if there is enough housing for them, so if you want to increase the population of the village you will have to build more houses.
Villagers count doors rather than actual houses, so to increase the population of your village, you should build houses with plenty of doors. For a door to be counted, it needs to go from “inside” to “outside”: i.e. you must have a roof to one side of it and open sky to the other.
Just adding more entrances and exits to the houses that are already there will help you increase the population.
Every three valid doors you add will increase the maximum population by one.
Build any new houses within about 32 blocks of the centre of the village to help the villagers find them.
Creating new villages
If you new build houses well away from any existing village, and somehow get some villagers to move there (perhaps by putting them in minecarts) you can found a new village.
You can trade with villagers using emeralds as currency. The easiest way to get emeralds is by selling things to the villagers, but they can also be found in chests or mined. Right-click on a villager to open the trading interface.
Each villager offers certain trades, depending on his profession. Click on the left and right arrows to see them all. After you have made the same trade with him a certain number of times, this will open up a number of additional trades.

The easiest way to gain emeralds is to move into a village and take over the wheat farming duties. You will also find villagers who want to buy many other things.
You will also find a lot of villagers trying to sell stuff. This can be a good way to get diamond tools early in the game if you’re lucky, or it can be a really expensive way to get some leather boots.
TIP: Some of the items that can be traded for are hard to get otherwise: Eyes of Ender, Saddles, and if you’re lucky, really useful enchantments. Save your emeralds for these!
Some villagers offer to perform a service such as turning gravel into flint or cooking fish.
Every now and then, a horde of zombies will attack the village. Will you save the villagers, or will you abandon them to their fate?
In one of these sieges, large numbers of zombies spawn, even if it would normally be too well-lit. They attack the villagers, and at hard difficulty levels, can break down doors to get to them.
If a villager is killed by zombies, he may rise from the dead and join them (50% of the time at Medium Difficulty, 100% on Hard).
The only defence the villagers have against zombies, unless you are feeling heroic, is Iron Golems. These will appear in large villages (16 or more villagers) and help defend against hostile mobs.
You can make an Iron Golem yourself, from 4 Blocks of Iron and a Pumpkin.
It will spring to life the moment you put the pumpkin on!
You gain popularity with a village by trading with the villagers, and you lose popularity by attacking or killing villagers or their golems. If your popularity gets bad enough, the golems will attack you.
