First, think about your character's origin. Were they born in a small village or a big city? Then consider their family. Maybe they had a strict father or a loving mother. Also, important events in their past can shape the back story. For example, if they witnessed a great battle as a child, it could influence their view of the world.
You can start with a simple concept like a character who was orphaned at a young age. Then build on it. Decide what happened to their parents. Maybe they were killed by bandits. This could lead to the character having a hatred for lawless elements and a desire to bring justice. Add in details like how they survived on their own, perhaps by learning to steal or being taken in by a kind stranger.
Begin by choosing a race and class for your character. A dwarf fighter might have a back story of being from a long line of miners in the mountains. His family's mine was overrun by goblins, and he vowed to become a fighter to protect his people. He trained hard in the dwarven military, learning all about weaponry and combat tactics. His back story could also include a personal vendetta against a particular goblin leader.
