Eminent domain is the right a government or state has to take property away from someone so it can be used for a public purpose. When a new highway is built, some people often lose part of their land by eminent domain.
Eminent domain is a legal term that's used when private property is taken for public use, to build a road, building, or public utility, or to protect public safety. Usually, when the government uses eminent domain to seize a property, it pays the owner what's considered to be a fair price for the loss. Eminent domain has been around since the early 1600's, when it appeared in a Dutch legal treatise, the original Latin phrase being dominium eminens, or "supreme lordship."
