Blocking is a gameplay mechanic that allows players to block several forms of damage.
Shields are used for blocking incoming attacks. Using one causes the player to slow to a sneaking pace, and after five ticks (0.25 seconds) blockable attacks and knockback coming from the front of the player are negated. Any effects from the attacker (e.g. wither or fire) do not afflict the defender. A successful block is indicated by a sound and the shield taking damage.
Blockable attacks include melee attacks, all non-magical projectiles, damage from Thorns, and some explosions. Creeper explosions or TNT ignited by another player are blockable, but TNT ignited by the player or by a redstone mechanism are not. Shields have no effect on other types of damage, such as fall damage and drowning.
Shields are used for blocking incoming attacks. Crouching (sneaking, flying downward, or moving downward in water) activate the shield. Shields also automatically activate when riding mobs, and there is no way to prevent the shield from being activated when riding mobs.

|Java Edition Beta|
|1.8||Pre-release||Added blocking, which at the time could be activated by using a sword. Also, blocking negated only 50% of incoming damage, rather than 100%.|
|Pre-release 2 ;)||Blocking now correctly deals damage in multiplayer.|
|1.0.0||Beta 1.9 Prerelease||Blocking now moves the player's hand, unlike previous versions, in which blocking moved just the sword.|
|The player no longer rises faster underwater when blocking.|
|Blocking no longer decreases fall damage. Blocking previously allowed the player to fall 42 blocks without dying, instead of 22.|
|1.9||15w33c||The blocking functionality of swords was removed and is replaced with the functionality of shields.|
|15w34c||When an attack is blocked by a shield, the attacker may be knocked back.|

|15w37a||Cooldown reduced from 0.5 seconds to 0.25 seconds.|
|Blocking now prevents some side effects like being set on fire when being hit by a mob that's on fire or being affected by the Hunger effect when being hit by a husk.|
|Arrows now ricochet off shields.|
|15w47b||Added shield blocking sounds.|
|16w07a||Added more variation of shield blocking sounds.|

- Blocking allows for the slowest movements possible. This can occur when the player blocks, sneaks, and moves backward while under the effect of the slowness potion while going through cobwebs placed above still water on top of soul sand that is placed on top of ice. This causes the player to move at about 1/200 blocks a second, or 2/25 pixel a second (1 Pixel every 12-13s) on a default 16x16 texture pack. Blocking while sneaking and with the additional events (but without slowness potion) allows the player go at roughly 0.023854961832 blocks per second (1 block every 41.92 seconds).[Java Edition only]
