What was the main purpose of the cartels and trusts created in the late 1800s?

The main purpose of cartels and trusts created in the late 1800s was to consolidate and control industries, thereby reducing competition and maximizing profits for their members. By coordinating production and pricing, these entities aimed to create monopolistic conditions that allowed them to dictate market terms and stabilize profits. This practice often led to the exploitation of consumers and workers, prompting government intervention and the eventual establishment of antitrust laws to promote fair competition.
