What term is used to refer to a type of business organization created in the 19th century that was meant to eventually produce a monopoly?

A trust

Explanation: In historical times, a trust, also known as a corporate trust, was a large business, or group of business interests with massive market power. They formed corporations and worked together in different ways. During the 19th century, the term 'trust' was used to refer to near - monopolies or monopolies in itself, in USA. During this time large companies relied on trusts as a way to consolidate power, and take as much as they can in an effort to claim significant power and thus massive share, within a market. This often led to businesses becoming monopolies, completing controling an entire market.
