Why do we have BLOOD TYPES?

About :
Before the 1900s, we took it for granted that all blood was the same and did not understand why sometimes blood transfusions saved lives, while in many other cases they led to the death of the patient. The discovery of blood types was the revolution that allowed us to safely transfuse blood from one person to another, and consequently, save lives that would otherwise have been lost. Today we all know that blood types exist, but what exactly are they? What does it depend on if you are one type or another? What happens if you give the wrong blood to someone? ????
