A more thorough explanation:

Definition: Brigbote (brig-boht) is a historical obligation that required people to pay a tax or charge on their land to help maintain castles, walls, and bridges.

Example: In medieval times, the king would impose brigbote on the people living near a castle. They would have to pay a certain amount of money or provide labor to help maintain the castle walls and keep it safe from invaders.

Explanation: The example illustrates how brigbote was a way for the government to collect funds for the upkeep of important structures. It was a way to ensure that the people living near these structures had a vested interest in keeping them in good condition. The obligation was often imposed on those who directly benefited from the structure, such as those living near a bridge or castle.
